How Much Power Do You Need?
Component     Requirement    Line(s) Used
AGP Video Card     30 – 50W    +3.3V
Average PCI Card 5 – 10W    +5V
10/100 NIC     4W     +3.3V
SCSI Controller PCI Card 20W     +3.3V and +5V
Floppy Drive     5W     +5V
CD-ROM     10 – 25W    +5V and +12V
DVD-ROM     10 – 25W    +5V and +12V
CD-RW     10 – 25W   +5V and +12V
7200rpm IDE Hard Drive     5 – 20W    +5V and +12V
10,000rpm SCSI Drive     10 – 40W    +5V and +12V
Case/CPU Fans     3W (ea.)    +12V
Motherboard (w/o CPU or RAM)    25 – 40W    +3.3V and +5V
RAM     8W per 128MB    +3.3V
Pentium III Processor     38W    +5V
Pentium 4 Processor     70W     +12V
AMD Athlon Processor     70W     +12V
For overall power supply wattage, add the requirement for each device in your system, then multiply by 1.8. (The multiplier takes into account that today’s systems draw disproportionally on the +12V output. Furthermore, power supplies are more efficient and reliable when loaded to 30% - 70% of maximum capacity.)

Adding USB card that needs power supply H520S

Just bought a 4 port USB 3.0 card for my H520S. I plugged it in and nothing. Then I read on the card manufacturer's website that I need to the connect the card to the PSU in order for it to work (there's an internal USB port on the card).
So I opened the PC and looked for an additional power source to connect the card to...but I'm not sure what I'm supposed to be looking for.
Is this doable on this model?
If so, what cables do I need and where do I connect the cable to?
Thanks in advance

hi,
This Device Will need a 4 pin peripheral Power Cable (Molex)
Like the one to the left on this photo
Since the unit is pre configured by Lenovo all Connectors on the PSU may just be enough for all what's preinstalled inside the unit.
Still Check the power Supply of your unit check inside if there is one available This cable is directly from the power supply, so once you open the computer case Look for the power supply and check the cables coming out from it and look for this connector here is a closer look

If you cannot find out you might need to Upgrade the Power Supply.

DA G4 w/GigaDesigns upgrade needs Power Supply... Again... Help!

Hi!
I installed a GigaDesigns Dual 7455B 1.0-1.2(GIG5D1012Q) in my Digital Audio DP G4 533MHz on 6/22/04. The power supply died within 9 months.
I then bought another power supply on 3/8/05 from DV Warehouse(they assured me it was new - far from it... anyway). This one is slowly dying on me. The internal PSU fan has long stopped working, so for a month or two, the G4's case has been open and the PSU sits on top of the case with a room fan cooling it down from 3 feet away. WHAT(in Lil' Jon voice)...
As you can see, my power supplies last for 7-9 months ever since I installed the GigaDesigns upgrade card.
Should I try the MDD PSU mod? Is there maybe a tech that does that in NY?
Or, should I get another Digital Audio PSU that I know will go in 7-9 months?
Is there another way to extent my power supply's life?
What do you guys think I should do? Any advice will be greatly appreciated!
Merry Christmas to all!

Two internal drives should not be a concern for heat, but the DIGI and video cards could be taxing heatwise and also taxing the power supply just a tad..
I don't have any recommendations for a PCI slot cooling fan - they're pretty generic items. When shopping, look for one with the highest CFM airflow and lowest dB (noise) rating you can find. This is a balancing act, as higher CFM ratings usually mean it's going to make more noise. Here's one from Antec at ZipZoomFly to give you an idea. Cracking the case door open isn't a good idea, as it negates the designed airflow characteristics and unless you provide additional airflow to the components, ad may actually make it run hotter than with the door closed.
WRT to dust - the most vulnerable spots for dust accumulation are the intake port at the front-bottom of the case right below the front drive bays, the PSU exhaust area, and the heatsinks on the processor(s). A quick blowout with canned air periodically is always a good idea to keep air flowing and things cooled as they should be.
Also, I do not see my topic in the topics list - I have to search for it. What did I do wrong? I guess there are different ways of posting. I just wanna post and reply without being asked whether my quetion was answered or not everytime.
I haven't posted a question since the changeover to the new Forum software, so I'm not the person to ask on this. I use the quick link to "My Posts" in the right sidebar to see what I've posted and jump back to it..

Help!!! in need of advice power supply is dead

Hey everyone i need some advice, i live in the uk and i have a 2 year old mac book pro and the power supply cable has heated so much that it has melted and stop working, what should i do?? should i just buy a new one or complain to apple and try to and get a replacement ??

This has happened to me before.
Just take the power supply and your laptop to your apple store (make an appointment at the genius bar) and they'll swap it out free of charge as long as ur still under warranty (or apple care)

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.

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.

G4 Dead. Do I need a new power supply?

Recently I tried to start my G4 and nothing happened. NOTHING. The day before I had shut it down using "Shut Down" and it hadn't shown signs of anything being wrong. Yes, it is plugged in.
Does this mean my power supply suddenly died?

I have been messing with my old G4 silver, trying to make it work for the grandchildren. It used to work OK, but the clock had to be reset everytime. Then we didn't use it for about 6 months. Now: Yesterday, I plugged it in and pushed the power button. After some normal-looking gyrations, the screen turned to a black pattern with the message, "You need to restart," which of course did not work. There also was some Chinese (I think) on the screen.
Replaced the battery with one from a friend's computer. Reset the PRAM. Voila, it booted and worked well -- for about 5 minutes. Went black. Would not turn back on.
Took the original battery to the neighborhood Apple shop. It checks out fine.
I put it back in, this time accidentally breaking one of the little plastic side holders. Having now read about the PMU here, I pressed that.
Voila. It booted up, even displaying the correct day and time, and finding the Airport connection. I deleted a few files and was just feeling really good when it went black again. Tried a different outlet. Nothing.
So, is there anything else to try? Is there any hope? I hear power supplies cost $100 or so and must be special ordered (therefore, kids will be home before the computer gets fixed).
I always get the most useful advice in these forums. Hope you can help me this time, too.

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.

HT5219 I have a macbook air (mid 2012) and a thunderbolt display. Do I absolutely need to connect the power supply together with the thunderbolt cable ? I found that the screen won't wake up if only the thunderbolt connection is plugged.

I have a macbook air (mid 2012) and a thunderbolt display (27'').
Do I absolutely need to connect the power supply together with the thunderbolt cable ?
I found that the screen won't wake up if only the thunderbolt connection is plugged. Is this normal ?

I just got my ATD and late 2011 MBP up and running. I've not tried running without the power adapter from the ATD plugged in, but I just tried and didn't have any problems with the display not waking. You may want to take your query to the ATD forum - https://discussions.apple.com/community/peripherals/thunderbolt_display - perhaps someone there has experienced a similar issue.
Good luck,
Clinton

Because the XP597A3 (actually any of these product numbers; XP597AA, XP597A3, XP597AS) is a HP 2011x 20" LCD/LED widescreen monitor. The OP was looking for an A/C adapter power supply for the HP 2711x 27" LCD/LED widescreen monitor, which is product # XP600AA or XP600A3. The adapter power supply I linked to, is the correct part for the 2711x monitor.... that is why not those other parts.
