Is it possible to change Power Supply unit for Lenovo H420 PC ?

I have 2 questions really as i recently bought this budget system.....I was amazed to see that the PSU was only 280 watts for this systemwhich kind of limits what Graphics card I can upgrade to.
My questions are :
1) is it possible to upgrade the Power Supply unit for the H420 from the default 280 W to say to a 400 W one?
2) If I cannot upgrade the PSU, what is the best performing Graphics Card that I can use in this system? It was pre-installed with a NVIDEA GeForce GT 520, which isn't the best around.
My 6 yr old Dell Dimension 8400 system with Win XP, which i have discarded allowed me to insert NVIDEA GeForce GT 240 card, which i think is a slightly superior card to the above one. Needed a 300 W PSU

Hi RBec and welcome to the community,
Is this your thread over there? If not, it gives a few options concerning the PSU.

Power Mac G4 MDD power supply unit/RAM

Hello,
I just bought a used Power Mac G4 (Mirrored Drive Doors) at a garage sale for $20. The owner said it works, but he took out the RAM, power supply unit and hard drive.
I would like to place an order for the RAM and power supply unit but I am not sure how I differentiate which power supply unit to purchase. When I try to look it up all I find it is that it had gods gift to worst ever power supply unit in the history of power supply units. It was the loudest most obnoxious fan set up or something of the sort.
Well bottom line I need to get a few replacement parts for the old G4 desktop and was hoping that some experienced mac hardware person could point me in the right direction. I am comfortable replacing parts I am just not certain what I need to purchase to install.
Does anybody know of any good 3rd party hardware that they could suggest for a replacement part?
Power Mac G4
Designed by Apple in California
Model No.: M8570 EMC No.:1914
Thank you very much :]
(I am pretty sure I posted this in the right subcategory, sorry if I did not.)
None of these model numbers match, but it everything I research says it was from this generation of G4’s. How can I 100% tell which one is the model I have?

I just finished rebuilding my MDD (FW800). As for finding specific parts for your machine, be sure you have the model number, or are able to differentiate between the models. That being said, most of the case parts are interchangeable. Problems can occur when swapping processors and failing to use the proper heat sink for that processor.
The best place (price wise versus availability) that I've found for MDD power supplies is on eBay. However, be aware that you will probably be getting it used. So either ask the seller if they will guarantee it for a specified period of time, or buy it from a seller that offers a guarantee (normally 30 days). If you get one that lasts for 30 days without any problems you've probably got a good one. Price is normally around $140 + shipping.
Another avenue is to try shopping the web (Google) for what you need. There are a number of great websites that carry what you may need, or maybe are looking for. Some of those to checkout are:
www.applecomponents.com
www.otherworldcomputing.com
xlr8yourmac.com
www.lowendmac.com
Additionally there are a number of case and power supply mods that can be done to quiet down the MDD. Apple doesn't necessarily endorse these mods, as they deal with changing power supply cooling fans, and/or the processor/case cooling fans. However, if your MDD is out of warranty, you practice safe electrical/static work practices as you're working, and you're willing to accept any negative consequences should those mods either not work properly or they happen to result in damage to other components, then do what you feel is appropriate.
As for telling exactly which model you have, and how it was originally configured when it shipped from Apple, research the serial number through this Apple website. Another way is to check the model number of the motherboard. This is located near the PCI slots, by the modem connection. It will have a number something like 820-1453-A, or 820-1500-A. Cross referencing these through Google can help tell which motherboard you have. As for the processor, you'll need to carefully remove the heartsink (5 screws) and look at the chip(s) itself. If there are two chips it's a dual processor, and if only one it's a single (Duh!). Then locate the small white sticker that's stuck to the processor card for the processor's info. It should tell you what you need to know about it. You can also look at the info inscribed on the face of each processor chip.
Important Note: Be very careful, and wear a grounding wristband at all times when when working on the inside, or handling any computer components. This is particularly true when handling the processor card, and here's why. Any static shock from you to the motherboard or to the processor could severely damage or destroy that component.
Here's another link to way of quieting the MDD.

Anyway, I hope these help you find what you need. Be careful!!

Can I install a G3 Blue & White power supply unit in a G4 AGP?

I have a G3 and a G4. The G4s power supply unit (PSU) short circuited a while back and I got a G3 as a replacement. I've tried to find a replacement power supply unit for the G4 and have been using the G3 in its place. Sometimes they appear on ebay but I usually lose the auction. But the G3 has upgrade issues that involve spending money on it. It's a Blue and White 300 MHz Yosemite while the G4 is the Graphite AGP 400MHz Sawtooth. RAM isn't an issue, processing speed is, the G3 is harder to upgrade. Plus I can put up to 3 hard drives in the G4. 2 ATAs and a SCSI. the G3 only holds 1 ATA hard drive. With 2 SCSI bays.
Anyway I'm leaning towrds retiring the G3 and rebuilding the G4 starting with the PSU. And I've seen on auction sites that these units are compatible with both Macs, the Blue and White G3 and the AGP and PCI G4. It is essentially the same 240 watt unit made by Delta Electronics or ATX..
However as I spent part of the yesterday dismantleing and cleaning dust out the Sawtooth's innards, and removing the broken PSU, I also noticed on the G3 that the PSUs cables are slightly different. There is one cable that is connected to the start button. On the G4 this isn't the set up. The start button's cable is linked directly to the motherboard.
To get to the point. Is this cable arrangement a potential problem that I should avoid by not tinkering with it? Or can I ignore this and install the G3 PSU in my G4? I'm preceding with caution and will check back here later in the day.
Thanks.

Thanks, Grant
Interesting opinion.. and funny too.
On close inpsection of the fron panel you're right the cable is a hard drive cable, and without a number. Whereas the connector for the DVD and Zip drive are numbered P7 and P6.
And in the G4 there is a slot for where this old connector went, but there's nothing to connect, no pins. It's as if this slot was evolutionary rump on its spine end where the tail ended, that the G4 designers left in or else they used left over parts from the G3 to save money.. This early G4, introduced in 1999-2000 is one evolutionary step above the G3 which was discontinued in early 1999. The G4 front panel has a slim grey ribbon cable leading under the chassis directly to the motherboard, along witha thin wire and small pin connector leading from the speaker.
There's nothing like a beakdown to learn how to rebuild your PowerMac. And I think most of the repairs are DIY doable. It just takes a few good screwdrivers, a little know how, some patience and a lot of spare time. All that and the correct replacement parts, if you can find them.
So I've finished installing the G3 PSU in the G4. It fits perfectly in and amazingly all the cables were long enough, including the cable to the ATA hard drive bay P2 and P3. Hard drive is connected, RAM installed, ready to go. All I have to do is plug the power cable into a power strip socket and hope for the familiar whirr and chime and breatha sigh of relief. If nothing happens then it prolly means the motherboard is kaputt. Or that it isn't compatible with the G4 architecture and it's back in the G3. I'll let the board know what's happened tomorrow. I'm off to Slumberland. ZZZZZzzzzz. rob

IPod HiFi A1121 power supply unit

Hi there,
I have an iPod HiFi A1121 and am aware it is discontinued. My power supply unit is the problem with mine, but due to the fact it seems quite complex and there are 3 different output wattages on it, it doesn't seem to be something I can just find a similar one of. Does anyone have a broken HiFi that they are prepared to part with, or does anyone know of anywhere I might be able to find a power supply unit from that would enable me to use my HiFi? It works on battery power and my friend has an adapter, that allows mains usage, but it means it will only play music to the same level as with batteries. Pleeeeeaassee could someone help me with any information? Thanks very much

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.

Installed new Power Supply unit.

For the past few months I have had the Sleep/Wake, Start-up problems wih my 1.8Ghz 20" G5 iMac, no iSight, no ALS, that so many G5 iMac owners have been experiencing, until it would not start up at all. No visibly bad caps on the logicboard but at least 4 bad caps in the Power Supply. I cleaned all the dust out of everywhere & I have finally gotten a new Power Supply unit, & installed it today, also changed the CR2032 lithium battery. I am ready to start up and I wonder what procedures should I perform to make sure I have covered all the bases to be back to normal conditions. Do I need to reset the SMU, reset the PRAM, Repair Permissions, run Apple Hardware Test on the Install Disc, etc.?
As usual, all suggestions are greatly appreciated.
Thank you,
John

hi Ralph,
Well, i started up & everything seemed to work OK, put it to sleep for about 20 minutes & woke it with the mouse, which I haven't been able to do for quite a while. I ran Apple Hardware Test from the Install Disc & everything Passed, hooray. Then I opened Disk Utility , chose "Macintosh HD" & ran Verify Permissions. A long list of "Permissions differ on ..." came up, starting with a "User differs on...".
User differs on ./Developer/Examples/WebKit/DiskCacheInspector/DiskCacheInspector.xcode/project .pbxproj, should be, owner is
Permissions differ on./Library/Application Support/Macromedia/Shockwave 10/Shockwave 10 Preferences, should be , they are
Permissions differ on ./Library/Internet Plug-Ins/Flash Player.plugin/Contents/Info.plist, should be , they are
Permissions differ on ./Library/Internet Plug-Ins/Flash Player.plugin/Contents/MacOS/Flash Player, should be , they are
Permissions differ on ./Library/Internet Plug-Ins/flashplayer.xpt, should be , they are
Permissions differ on ./Library/Preferences, should be , they are
Permissions differ on ./Library, should be , they are
Permissions differ on ./private/var/log/secure.log, should be , they are
What thet should be & what they are are a lot of r's, w's & x's. I didn't type here what it said they are or what they should be because I don't know if there might be a security risk or not. Probably concerned over nothing.
Anyway, should I Repair Permissions or are they supposed to differ.
Thanks again for your help.

Looking for a Power Supply

Hi!
I am looking for a power supply for my sound blaster speakers.
The model is SBS 380. The power supply works on a 4.0 volt.
Anyone who would have a spare one to sell or to inform me where
to buy one would be most appreciated. ( I'm in Canada )
I have be been to several stores but no ones carries 4 volts power supply.
The one I have is no lomger functional and the sound is excellent from those speakers.
BTW, Craetive no longer support them and have none in stock.
Thanks,
Gerry

Jason, I think he would have some trouble getting them shipped to Australia from one of those stores. Beside that it would be less from newegg, look at the additional 20% off promo and free shipping. For me it's 3 days from order to delivery from ZZf and newegg.
Yes, one of the Corsairs but not HX but as mentioned TX or VX, also PC P&C 610. Ignore watts, go by +12V amps and as FP mentioned consider future need for more power when choosing. Nowdays the VX450W (+12V~33A) would be considered minimum to get and also would be considered weak for many current systems.

Do I need to replace video graphic card or power supply unit on hp compaq presario sr2180nx

hello all
i saw a similar post over 4 years ago, however it doesn't address my issue.
my pc started stalling when i attempt to turn it on. It wouldn't come on. Then after several tries every now and then it would come on. I was told through searching that it could be the video graphic card or the power supply. Therefore once i had the computer back on. I never shut it off. However, i could reboot and it would come on.
Now it won't come on again. So i don't know what to replace. The video graphic card or the power supply. If it is the graphic card, do i replace the one previously installed or add a new one. And if adding a new one, what is recommended to be compatible with my 300 watt supply unit? I'm lost as what route to take and how.Below are the details of my unit.
HP/Compaq Presario SR2180NX desktop PC with a P5LP-LE motherboard with an Integrated graphics using Intel GMA 950.
*Integrated video is not available if a graphics card is installed.
Also supports PCI Express x16 graphics cards
300 watt supply.
thank you in advance for any help you can give me.

Is there an add-in video card in the slot? If so, remove it and try to turn on. If the problem is the video card it will turn on. If not it is the power supply.

My Time Capsule has just failed, 2 months after the end of 12m warranty. same old known power supply issue, "just unlucky" says my local Apple service center. ***?

i bought a 2TB Time Capsule in Sep 2010. its just failed last week, less than 2 months after the expiry of the 12month warranty.
and 3 months after the end of Apple's offer to replace all the many Time Capsules that have failed previously due to this same fault.
nice timing guys.
"yeah, its dead. same old known power supply issue", says my local Apple service center, "just unlucky".
huh? "unlucky"? you sell products with known defects, and when it fails i'm "unlucky". nice.
"OK, anyway, how much to fix it ?", i ask.
"you can't fix them, its closed", is the reply, "you have to buy another one".
"hmpf. OK, how do I get my backed-up data off it ?"
"you can't. we could try break it open and recover the hard disk i guess, but no guarantees we'd get it, and you'd have to pay for us to do that, whether it works or not of course".
"er.... is there a hidden camera in here? are we on TV? you can't be serious ? ..and this piece of garbage is what i've been using for a secure backup of my precious, irreplaceable, priceless personal data ???"

ceeb28744. Welcome to the Apple Users Support Community. Sorry to hear your TC died! You said it was a 2TB so I would guess it be the model A1355/MB997LL/A or MC344LL/A. Believe it or not all users of these time capsules will eventually experience this problem like you have. There is a 99.5% (or better) chance that the only thing that is wrong with it is the internal power supply. If you will go to this site.... https://sites.google.com/site/lapastenague/a-deconstruction-of-routers-and-modem s/apple-time-capsule-repair and once there look over at the left side and you will find:
Apple Time Capsule Repairers and from that list you will be able to choose from a list of individuals that could repair your TC and have it returned to you fully operational again. The individuals on the list are hardware technicians and they can save you a lot of money and time.

Need a piece for my power supply cable

So my mag safe power supply for my Macbook Pro has the two little "hooks" that pop out and allow you to wrap the cable around them for travel. One of the hooks broke and during the process of trying to get it fixed through Apple, by replacing the hook, I was advised you have to replace the whole thing.
I was wondering if anyone knew any place to get these little guys or had an extra one lying around that they would be willing to sell via a Paypal payment.
Thanks!

Alternative suggestion I gave to one of my clients: buy another power adapter, then use the "broken" one permanently at your desk. So rather than rushing out of the house, forgetting to pack your charger, instead leave one of the chargers in your bag. When you get home, you plug in to the "permanent" desk charger. The one on the desk would never be coiled up, or coiled up in a different way with wire ties or something. And if the charger is under your desk, well, out-of-sight, out-of-mind.
I've done this for years, ever since that first time I forgot my charger and blew my school assignment because no one on campus had a compatible charger I could borrow. While it is an additional expense, it's also a comfort that when I break the charger, I have an immediate spare, or have a second charger for troubleshooting.

Picolit Power Supply Unit

I have the following PSU in my Envy 750xt: IPS,ATX,Picolit,500W,EStarBronze,5Vsb/4A - 746177-002
My question is will this PSU work with an uninterruptable power supply that outputs a stepped sine wave (only when on battery power)? I am also curious if this PSU uses Active PFC.
Thank you.

The P/S requirements are overstated.
The card draws a max of 29 Watts and is a favorite to install in the HP business desktops with the 240 W P/S.
It is also the optional graphics card on the HP Elite 8200 SFF with the 240 W P/S.
