Help : Simple Power Supply Filter

First , thanks to everyone who answered my question on "time step too small".
I am in the filter stage of a very simple power supply. However, when I connect a capacitor to the output of my rectified signal, the output signal of the load is not what I expect to see.
I expect it to be fairly constant, and located at the peak of the input voltage.
Any help will be deeply appreciated.
I have attached the circuit to it.
Thank you.

O.K. Here's a picture of your circuit with the PI Filter attached to it. I just arbitrarily selected the components to use. I used low value caps so you can still see a slight ripple on it. A larger capacitor at the end of the bridge will filter this ripple almost completely out. Most circuits I have seen usually have this cap set somewhere in the 100uF-300uF range and the output capcitor in the range of 10uf-50uf range.
I can't remember the formylas for designing a PI Filter, but I am sure if you search the internet there are resources that can help you with that. I think I may refreshen my memeory on this subject as well.
Here's the picture and I hope this works for you.

Need help with power supply & graphics card upgrades

I have a HP Pavilion p6320y that I bought 8 months ago. AMD Phenom II x4820 Quad Core processor. I play WoW and since the last big patch, have been suffering with low fps. I updated drivers and followed all the advice given to me by Blizz and finally figured out that my Nvidia GeForce 9100 (integrated graphics) isn't good enough anymore.
I checked my computer and discovered that I have a 300w power supply (12V) and read on another post here that something stronger than 300w is needed to run a decent graphics card.
Now for my questions:
How much of a power supply can I upgrade to without hurting my computer, but will be enough to run a good card?
What would be a good graphics card for this computer?
I've been looking at the Nvidia GeForce GTX 460 1GB GDDR5 PCI Express graphics card and wonder if that will work on my computer. Most of the nicer cards seem to be the PCI Express and I'm not sure if that will work.
Any advice will be most helpful. I have some experience with the inner workings of my PC and would like to fix this myself instead of running to the closest computer shop and paying someone else to. Thanks!
This question was solved.

Well, you are starting out from a fairly low baseline with the integrated graphics. It will not cost much to have a substantial increase if all you want to do is run WoW without error messages. Yes, the 300w power supply is an issue and rules out any card that will require its own power (i.e. needs its own power cord like a hard drive) but there are several mid-grade cards that can run off bus power alone (i.e. just from the pci-e slot itself). Just taking a quick look at newegg.com I see the following:
GeForce 9400 under $50
Radeon HD 4650 under $50
GeForce 9500GT a little over $50
Any of these should get you where you want to be and not require a PS upgrade. The slot you have available is a PCI Express x16 slot so don't look at AGP cards; they will not work. If you want to install the card you mention you need to get a better PSU.

Need Help with power supply reccomendations for my graphics card

hi
i have a MSI GeForce GTX 780 Graphics card... i built my own system, i also got a rosewill rx750 power supply in it which i think is causing me problems, the computer works great until i get into games like titan fall and try and get into a game then it restarts the computer on its own.. has done this with a few games, but it works fine when surfing the net and so forth, i have read its to do with the power supply being week and also read my chosen power supply isnt that good... anyone got any recommendations for me that i should look at or am i looking in the wrong direction with whats wrong with my pc... any help would be great thanks

yes the PSU is the most important choice out there and corsair and seasonic are the best out there! (never buy cheap PSU's as like abvolt said a cheap one can easily kill your more expensive parts)
Cheap PSU = made of the most cheap parts they could get "think cheap shanghai parts are used that may be of any quality good or awful as its just what they could get for the lowest price" (ever bought anything that was super cheap they break very easily)
Quality PSU = the use of good quality well made parts and will have very good testing done on them to make sure they are stable and pass very tight regulations and conform to specs for 10-30 different factors each.
a cheap low quality PSU I class as a paper weight as it will never go near a computer (maybe i would use one as a basic bench PSU for things i do not care if they die or just for testing a fan or something that rubbish dirty power is not really a major problem but silicon is not tolerant to dirty power and will kill parts)

I think i saw new PSUs in the US offered for about $140. Here in Europe they are twice as expensive...
however, temperature problems might indicate a different source for the problems. Are the venting channels clean and the fans running? The G5 processor is quite hot - since short i have an Intel, and it's much less heating up! - especially if you have graphics or many windows open. (It depends also n which model you have)
There are also DVM's (Digital Voltmeters) with which one can measure a capacitor, but my attempt to do this with the capacitors on the PSU was not successful, probably due to the residual capacity of the surround print parts.
If you have access to a decent fast oscilloscope, you can check the PS voltages. If they are stable and without spikes, then the PSU is fine. If they are spikey, then a new capacitor can help.
Hope this helps

D10 power help -- psu power supply 10-pin power adapter

i have a d10 motherboard, and i've fit it into an intel server chassis.
the PSU installed has an aux-power adapter, but it is a 4-pin used for intel server boards.
i need to convert some of the extra cables from the PSU in my chassis to work with the 10-pin connector on the motherboard (next to the 24-pin connector).
if someone could help me out and maybe provide me with adapter information, voltage information, any information.....that would be a great help. a diagram of sorts would be greatly appreciated. or maybe even a picture of the actual 10-pin cable going from the PSU to the motherboard??
thank you!!

Hi
Yeah take the MB out of case and plug in only: CPU, PSU, 1 Memory stick (to secend slot from CPU) and monitor to MB back.
If it dont boot up after that and show error for not finding KB, then what code it has on debug led?
Hope this helps Cheers Mummy
Disconnected everything from motherboard except CPU + cooler & second RAM DIMM, set it on a cardboard box, plugged in 20+4 main power connector and the 8 and 4+4 CPU power connectors, then tried powering up again. Couldn't connect a display because I don't have an HDMI display handy - but I figure that doesn't matter much if power isn't even on long enough for BIOS to begin loading anyway. Nothing new happened. Unfortunately, a debug code never comes up.

Help spec power supply

I am building an AMD 64 machine with the following specs:
MSI K8N NEO FSR
AMD 64 3000
1 Gig O' Ram
SATA HDD
1 floppy
Dunno about video yet
a couple of case fans + the CPU fan
DVD R/W
Heres the problem:
I read somewhere on here that I should have at least 24A on the 12v line for the CPU from the PSU. I got the datasheet for the CPU and found that it should use 89W peak @ 1.5v. That comes too 59.333A @ 1.5v. Assuming 75% efficiency for the conversion I get 6.18A for the 12v line (59.333A/12=4.944, 4.944*1.25=6.180A). What am I missing here? Did I screw up the math? Will all of te other bits actually pull 17.8A?
What should my PSU specs be?
Thanks in advance

so much choice and info around people will recomend thier own personal fav`s but a single rail (12v) with as much in the amp department as you can go for is where it all seems to point. 450+ watts
pc power and cooling
enermax
tagen
etc all got good reviews . but the $£¬ is also an option of course.
i just got my pc p and c 510 deluxe from a tt 560 and my 12v ams gone up by 10 a
for slightly less but more reliable wattage
ok some may say overkill but better to be able to drive at 100 and only use 70
than limit yourself to 70 and drive at 70 all the time i guess.

Help for beginner: Need labview signal to power on =2 actuators of 8 with one power supply

I am a beginner in using labview. I need to use labview signal to turn on >=2 ac 8 actuators with one power supply. The 24VDC, 0-3A power supply is enough to drive all 8 actuators which need 24VDC and 0.1A current. So the main function is like turning on 2 or more than 2 switches in series with the 8 actuators with one power supply. Any suggestion of some simple module for this purpose? Thanks.

Maybe I didn't say the question clear. I have one power supply (24VDC, 0-3A) and 8 solenoid valves (24VDC and 0.1A). Two valves (or more than two in future) have to be activated each time. I would like to find something that can work like switches installed in series with the valves. Then I can wire the valves (with the switches) in parallel with the power supply. As I turn the switches on and off with signals from Labview board, power to that specific valve will be turned on and off.
Any advice for this kind of switches or any module that can be controlled by Labview signal? Please help! Thanks.

Power supply fan dead - help? (400mhz AGP G4)

Hello!
Unfortunately, my PowerMac G4, a 400mhz, AGP Sawtooth model, has a dead fan.
Over the last few weeks, I've noticed that my G4 has been running quite hot. I figured it was due to the hot dorm room that it's being used in. Then, I noticed that when it booted up, it would occasionally make a vibrating, or rattling noise - I figured the fan was wobbling. Since air was comming out of the fan opening at the top, I didn't worry about it.
Today, I used the "Temperature Monitor" widget to check the temperature of my SMART Hard drive (the G4 itself is not sensed). It was 133 degrees!!! This is the bay on the back-right, just under the CPU fan. I looked at the fan again - not much airflow. I pulled out a flashlight and pointed it in, and the Fan that's inside the power supply unit is dead.
So, how can I fix it? It's far far too hot, so it's not usable until I can cool it off. The first idea I had was to take a particularly powerful desk fan, and make a paper "tube" that connects both to the G4 and back of the fan - so it'll pull the hot air out. Needless to say, this is not a good log-term plan as it's easy to fall apart and will have leaks, but it works for now. I realize you can buy power supplies, but for ~$100, it's far too much for the old G4.
Second idea: The fan is inside the "non-user servicable" power supply, but it's also next to the back of the G4 - right inside what appears to be a panel that holds the power supply in. At the very least, I'd like to make sure that the cable is attached and not loose, but I have to open the back. Is that possible or safe? If so, can I replace the fan?
My third idea was to attach an extra fan to the inside of the G4, on the outside of the power supply - pushing in. Unfortunately, the IDE cable from the DVD drive is in the way, and there's not much room for a fan. Plus, there's no fan power supply. Is it possible to convert an ATA power plug (there are 7!) to a fan-power supply? I'd require a small circuit and a lot of resistors, obviously! If so, what would I need to do to convert it?
Thanks a bunch,
-Dan
15" 1.67 Powerbook G4 (Jan 2005), 400 mhz AGP Sawtooth G4 Mac OS X (10.4.8) 4G Clickwheel and 5G Vid iPods, 2G iPod shuffle

Thanks!
Interesting, this "Piggy back power adapter" will allow me to plug the fan into one of the ATA/IDE cables? Or do you mean the extra port on the power supply? (it has one plug for the outlet>G4, then another to support something like a monitor or similar) The G4 has a DVD burner, but no ZIP drive, so this is quite do-able if it uses the ATA power.
When you say "lower rear", do you mean at the bottom? Below the power supply, to the right of the PCI slots? If so, this is the inflow for the CPU fan! I can understand mounting it outside the current outflow-vent for the dead power supply fan, although I'm not sure the best way to proceed with attaching the fan.
Another question: what tools and supplies will I need? I may need to remove the plastic cover on the back of the G4 - the one that is outside the power supply - as there's a gap between the gray plastic and metal chassis that lets air from outside the machine come in. The screws for this cover use a funky, hexagonal screwdriver. If I need to take this cover off, what kind of screwdriver will I need? Also, should the fan not include screws/etc, what's the best method to attach it? Glue?
Secondly, to cut a hole in the G4, will I need some variety of drill? I don't have one, so i'll have to borrow one... Since there's nothing in the ZIP slot, I can run a cable out through here (assuming it's long enough), and make a new bezel to keep the airflow inside intact.
Ah! One other (somewhat related) question: my USB 2 card includes a power adapter, for use when several un-powered devices (flash drives) are attached. It works just fine with a flash drive and a small media reader, but it's slow to sense the drives - I think it's low on power. Unfortunately, this power plug uses the same variety of plug as the floppy disk drives found on many win-boxes - of which the G4 possesses none. Is there an adapter/cable for this purpose?
Thanks, this is a HUGE help, I appreciate it.

Help with using itunes with 4s library after i upgraded to iPhone 5 and computer power supply went

long story hopefully an easy fix....
on wensday my power supply went and had to ship computer across country to Puget Computer Systems as we weren't sure if it was power supply or mobo...luckily it was power supply.
i daily backed up iphone 4s with itunes (10.7) as i do all music manually, playlists, etc. have like 3,000 plus songs, videos, audiobooks, mail aaccts and about 48 apps.
so next day (sept 19th) apple comes out with iOS 6 which i update my 4s to with no problem. I wanted a day to play with it to learn my way around.
next day i wait in line for 8 hours overnite and was #2 in line at apple store for my ATT 32gb white iPhone 5. while at apple store I get my icloud backup which gets all paid music,apps, etc since itunes version 10.3 (i always did both backups so as not to lose my contacts more than anything.
I have other paid stuff that is in library on computer along with audiobooks and about 2700 more songs.
my icloud backup put the playlists on iPhone but not most of the music for them as lots were ripped from my cd's.as i double them up making a copy on iPhone and a copy on itunes.
So I have been using iPhone 5 with no problems just don't have all of itunes library on it. My computer is coming back this week how do I plug in iPhone 5 via USB (which will be seen as new phone even though it has same name) and use my existing iTunes 10.7 library which the backups in iTunes still has iOS 5.1.1 on it?
There must be an easy way of doing it as i don't want to wipe off iphone 5 again as i don't see any purpose my library is all organized perfectly. I know my way around windows 7 pro 64 bit pretty well just don't know what itunes is going to say once it sees "joe's iPhone" again and installs the usb drivers and icon for it. what will it ask in regards to library and how do i use it with previous iOS on it?
Thank you very much for the help as I am going to need it.
yes i broke the cardinal rule of cross posting and apoligize for it just amazed i couldn't find answer via google nor any apple store genius knew it either.

Hi All,
Any help?
No one has any answers here amoungst all this apple knowledge?
Thank you

Help I think my power supply is going bad! Where can I buy parts?

I am getting random reboots and it doesn't seem to be the OS... My first guess is the power supply but I can't seem to find one to buy... Does anyone know where I can buy one at? Is there a good place for parts for the MEGA 180?
Thanks
Mobile Bob

you need to post more information about the problem you're having, before we start pointing the finger at the PSU, which is the one part that is difficult to obtain now
>> Getting help with random restarts and blue-screens <<
Post more info on the hardware in your Mega PC, refer to >> Moan Guide <<
Download Speedfan and use it to measure CPU temps both at idle and under load and post them here. >> How to use Speedfan <<
Test your memory using >> Memtest86 <<
The thing is that windows never leaves an error... I get nothing in the event viewer except windows was shutdown error no other errors are listed so I don't think it's windows... I ran a CPU Burn in test for over 24 hours and never had a problem so I don't think it's heat either... And the reboots are quite random I will go two weeks without one and then get them two and three times a day... To me the power supply seems to be the easiest answer but since there hard to get I guess it's not so easy to check eh...
I have done the fan mod (Turning it so it sucks in cool air) and I have a slot fan dumping tons of air out the back so I don't think it's a heat problem... I started to have the problem running Windows XP SP2 so I did a complete reload from scratch to Windows Vista (I know not completely supported but it works fine) and am still having the same problem... I have a Haugpauge 150 pci card, Haugpauge USB2, A usbuirt pluged into usb and thats about it... 2 gigs of ram 2x1gig sticks from Crucial, yes I have already run a memory check and it passed...
Is there not anywhere to get a power supply? Or is there another model that fits the mega 180 case?

Help! I need to upgrade my Dell Optiplex GX260 (tower) power supply!

Hi,
I plan on taking a trip to Best Buy today to purchase a video card and power supply for my Dell Optiplex GX260 (tower). I am looking to get at least a 500W power supply. Can you tell me the BEST power supply that will work/fit that Best Buy sells? Thanks very much.

I see that you posted back in March of 2009 so I hope that you haven't already fried a motherboard or PSU while learning the hardway, as I feel that I almost did. We have a Dell GX260 that my daughter wants to play some games on but I found out that the Graphic Card (ATI Radeon 7500 series) was not good enough for the games that she wants to play so I decided to upgrade the graphic card, unfortunately I found out that a lot of newer cards have PCI-Express connectors and not the PCI I need. As well, I found out that most of the PCI cards above what I have need more than the 250Watt power supply that I have. So I thought, why not just upgrade my my PSU and then I found out that Dell actually rewires their PSU differently than the industry standard ATX connectors but I see a lot of post and recommendations from people that say that you can use any store bought PSU to upgrade your Optiplex GX260 but BEWARE that if you bought your system after late 1998 then you have a Dell system that has their own proprietary wiring configuaration and even though you can buy a standard ATX PSU at bestbuy and it will seem to fit properly, it will either fry your new PSU or worse yet, it will fry your motherboard as well. In fact, I went to bestbuy three days ago and bought a graphic card and the salesman told me that if my PSU was not at least 300Watt, which is what the card required, that I can come back and buy a standard PSU from them and that would fix the problem. The salesman even knew that I had a Dell System so I wonder if BestBuy would be willing to replace my motherboard if I had fried it based on what the bestbuy salesman told me to do???? Anyway, read this link http://www.informit.com/articles/article.aspx?p=339053 and see what you think!! I am glad I stumbled across the information and plan on upgrading my PSU with a compatible Dell PSU or look for a Dell Converter (if there is such a cable) or just replace both my PSU and Motherboard as directed. I also think I might actually build my next PC from scratch with all industry standard parts, as I was very ignorant up until now that Dell was doing this to their products and I have 3 of their systems in my house....but no more!!! I did find a Dell compatible PSU 500 Watt on PCPower.com but it comes with SATA drive connectors and my Optiplex GX260 has IDE connectors so I don't know if I can get a SATA to IDE conversion or not but as you can see I am still researching my options. I might actually find it will be cheaper to just buy a new system or build the one of my dreams!!
I know I wrote a lot but I hope that this information is helpful to someone else out there who is in the same boat as me.

I need help to replace my power supply for the hp pavilion elite m9510f

This computer has given me many problems since I bought it in '09. From graphic card fan issues, a hard drive crash, and now the power supply has failed.
I did the blow dryer trick but it still ends up breaking a week later. I want to know what new power supply should I buy. One that will be able to fit in the hp pavilion elite m9510f and is an upgrade to the 350w that it has. Maybe somthing under 60-70 dollars if possible. Thanks for any help.

It appears to be a normal case and motherboard. A normal ATX supply should work: http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=50001333&IsNodeId=1&Description=Computer...
Just an example of what is availble, but most any should work as long the physical dimensions match the one installed now.

Problem with NEW H520 when installed new power supply & graphic card. Please help!

My H520 was working perfectly and was running FAST..especially when rebooting. ( It was AWESOME! )Then I installed a new power supply (Coolmax 400w) and a new graphic card (Sapphire Radeon HD6450) and then everything changed. Now my computer is booting very SLOWLY and all the programs are taking a long time to load too. I was getting a black screen for almost a full 2 minutes before the windows 8.0 screen would finally load up and then it hangs there for a few seconds and finally goes to the start screen in windows. But BEFORE I installed this new hardware, when I would reboot, I would see the Lenovo splash screen come up for a few short seconds and then it instantly went to the windows welcome screen. And even then I would barely have enough time to see the welcome screen before it instantly loaded into the windows start screen. Everything would load up fast on the desktop too and we'd be good to go. It all took about 30 SECONDS.
But now? It takes MINUTES to get everything going. After it FINALLY loads up (it takes almost 2 full minutes now!), everything hangs up. When you first click on the desktop, it takes a few seconds for all of the icons to pop up. Before I loaded the new hardware, everything loaded up instantly. I didn't even see the icons load because they were already there. But now I have to wait for them to load up before I can even see them. And it's like that with every program and web browser I try to use now. Everything hangs up at first and then finally loads. The programs work but they are sluggish.
So I uninstalled the new power supply and put back in the original 280w power supply and I took out the graphic card but it did no change. The machine is STILL running slow on everything it does and booting very slowly.
I have seen this problem mentioned elsewhere about Lenovo computers but there is never a solution. Please help! It took me a long time to save up for this computer and I have been babying it ever since. I will never be able to afford a new one or pay for tech repair. I need to fix this! I was so thrilled with this computer before the hardware upgrade. This is devastating to me that it is working so poorly now when all I was trying to do was upgrade it a little bit.    Now it's performing horribly and it's only 6 months old.
I ran a four hour test on the hard drive and it is fine. I ran all the system clean ups, optimizations, registry cleanups, windows disk cleaner, defragger and virus scans. Nothing is showing up as not working but there is CLEARLY a problem. It was never this slow.   And why is it STILL acting this slow even after I uninstalled all of the new hardware that made it start acting this way and went back to the original setup?
I'm trying to run a memory test on it now but the BIOS will NOT allow me to select another drive to boot from so I can't boot from the flash drive or CD drive to run the memory test. I have NO IDEA what to do next and I am starting to pull my hair out in frustration.
Please, is there anything that can be done to make it better again?
Any help would be HUGELY appreciated. Thank you!
Sincerely,
Jennifer

I totally give up!! I restored everything to the ORIGINAL state with drivers AND hardware and STILL everything is not working properly like it was BEFORE the upgrade.
So this has been the WORST experience with Tech support EVER!! I have spent DAYS on the phone for HOURS with these technicians and nobody seems to know what they are doing. They put me on hold every 10 minutes and are gone for 10 to 15 minutes and when they come back, they seem all set on a new solution but when you ask them questions about it, they have NO CLUE how to answer and then they put you on hold again. Nothing gets solved and after HOURS on the phone, I just tell them to stop because we are getting no where but running around in circles that make no sense. THIS A NIGHTMARE!!
So I totally gave up on being able to upgrade this machine. To any future buyers, I STRONGLY recommend you do all upgrading BEFORE you get it home for the first time. Make sure you have your power supply and graphic card INCLUDED before you bring it home or you're mostly likely going to have a NIGHTMARE upgrading it later.    Technical support is a HORROR STORY and expect to be WAITING for LOOOOONNNNG periods of time both ON THE PHONE and ONLINE and probably ending up with NO SOLUTION in the end.
I've VERY upset with how this turned out!! I'm just gonna have to deal with the fact that my computer is permenantly messed up and NOBODY AT LENOVO knows how to fix it. So I'm stuck.
I decided to send back the new power supply and the new graphic card because of this nightmare with tech support. I put everything back to the way it was when I bought the computer and it is STILL acting up!! I just want to revert it back to factory settings .. INCLUDING THE BIOS... but Lenovo said I have to send the WHOLE computer back to them to do that. All I can do from home is restore from a point in the hard drive and that's not enough. I need a TOTAL CLEAN INSTALL. Everything needs to be wiped out and reset, not just restored to a previous restore point. I've done this multiple times and all it does is erase all the programs and stuff I put on the computer. The drivers and other codes are still the same. And then bugs come up and things get all wonky. I NEVER HAD THIS PROBLEM BEFORE I TRIED TO UPGRADE IT!!
I am NOT comfortable with Lenovo's "solution". I do NOT want to send my computer back to them for them to reset it with factory disks ESPECIALLY when they stated that they are NOT responsible for any damage in transport or otherwise. I have to buy extra packaging to make sure it gets there safely. They told me to use the original box and packaging, that is the only way they can be sure it will get there safe. Who has the original stuffing SIX MONTHS LATER?!?! I don't want to be sending my computer across the country to get jostled all over the place and have that add to the slowness of the hardware because it was jostled.
Can't I reset it from home? Can they not send ME the disks instead of me sending my whole computer to them?
I'm so incredibly frustrated with this. I hope somebody answers quickly and that I don't have to wait DAYS to get a response again.
I absolutely LOVED my Lenovo computer! And then I tried to upgrade it. BIG MISTAKE!! Now everything is totally messed up and Lenovo's customer support for technical problems is HORRID!!
Somebody please help. This is driving me crazy with frustration and totally breaking my heart. It took me a VERY long time to save up for this computer and it was my most loved possession. It was a reward for a lot of hard times and now it's all broken and acting slow. And it's only 6 months old.
Is there a solution to this very frustrating problem?
I just want it to go back to the way it was before.
And is there a very low cost KNOWN TO WORK WITH THIS MACHINE upgraded graphic card and power supply? Is there a very specific brand and make? If so, could you let me know what it is in case I try to upgrade it again someday?
Thank you for your time and for reading this!
Please have a FANTASTIC day today!!
