So I bought a GPU that required 300w, But my PSU that came with my computer only supplied 240w. I ended up buying a power supply unit that supplies 320w because I couldn't find a 300w specifically made for the stupid Intel motherboard that doesn't have 20+4 pin slots. So after installing the New PSU correctly. (Made sure all wires are connected. Only one stick of RAM. All USB ports are empty. Plugged into the wall socket.) My motherboard doesn't light up. Nor will my computer do ANYTHING. No sounds other than the clicking of the power button. No fan movements. No beeps. Nothing.

SO! After scrounging the internet only to find people who had different conditions to these similar situations than what I have. I decided to snap pictures and let you guys figure out what is wrong because Quite bluntly. I. Don't. Know.

You may notice the OBVIOUS discrepancy of my new power supply unit not being inside my PC. Well, It's too FAT so, I'm just going to cover up the giant hole with something after I get this b*tch to work.

I don't know what's wrong since the labels say it should work just fine, But for some reason; It doesn't make my computer do anything. But with my standard 240w Power supply that comes with the computer, It works without a hitch. Even when THAT is outside of the case.

I would REALLY like to install the new GPU so I can run my games that use 3D graphics at more than 20 FPS.

 

NOTE: Attached is a 64-bit Dxdiag .txt file. If you can't tell, I REALLY want this to work, Since I have never messed with the (Physical) insides of a computer before.

I'd suggest checking your connections.  I can't see the pictures right now, so I'm guessing.  The most commonly missed power connector would be the four wire plug that goes near the CPU.

These seem to be proprietary PSU's which don't resemble ATX standard power supply wiring.  I guess there are two main possibilities (assuming all connectors that should be plugged in are).  First is that the 320w PSU is dead on arrival, and it doesn't do anything because it's broken.  The second is that it's wired differently from the 240w PSU, perhaps intended for a different PC, and to (possibly) make it work could involve re-wiring the connectors.  To find this out you would need to access the wiring schematic from the manufacturers service manuals (maybe something is available online).  You may take a guess at whether this is likely to be the case by comparing the colour of the wires going into each position on the connectors on the different PSU's, but I caution against doing anything without wiring diagrams.  Get it wrong and.. bang.

 

My personal view is that this is a small form factor PC, which will only take half height (low power) graphics cards.  They were never intended to have upgradeable power supplies.  The "minimum power supply wattage" recommendations given by GPU manufacturers are at best loose guidelines.  For example, Nvidia recommend a 300w PSU for a GT 720 GPU.  The maximum amount of power this GPU draws through the PCIe slot?  19 watts.  HP offered these PC's from outset with optional GPU's (Quadro NVS 295, Quadro NVS 290, Geforce GT 310, Radeon HD 4550).

 

The power consumption rating for each of these are as follows:

 

GT 310 - 30.5w

NVS 295 - 23w

NVS 290 - 21w

HD 4550 - 25w

 

I think you could fit a graphics card (single slot, half height) with a power requirement similar to one of these cards with the original PSU.  For anything more, you might be better off with a different computer.

Damn. Well thanks for the info on GPU's that can work. I guess my problem is solved. Now another problem has risen, To pay for the shipping and handling for the GPU and PSU that I bought.

 

Mark this as solved I guess.

A GeForce 710 which needs 300w. Had no make it low profile by moving the VGA cord to another PCI Slot.

The 710 should work fine.  According to the specs it draws about 19w. http://www.geforce.com/hardware/desktop-gpus/geforce-gt-710/specifications

So... It will work fine on a 240w? I tried running Minecraft with it and I hit a smooth 100 FPS on pretty decent settings, Then I launched a more expensive game like StoneHearth, Then after a few minutes in game, My computer just shut down calmly, No damage to anything, It just... Stopped.

It should do yes - on the basis that the Geforce GT 710 doesn't draw any more power than the optional cards the PC was sold with when new (the NVS 295 etc.). It really doesn't.

 

Did it just switch off suddenly? No Windows shutdown? That is possibly a PSU issue, certainly they can do that when overloaded. I guess excessive heat could potentially cause that too, as could a power outage.

It shut down just instantly. And I dont recall any optional cards coming with the computer I got. I DID put my laptop's harddrive IN the case and formatted it so I can have more space as some sort of internal external drive.

I think what happened is that my PSU overloaded since while I was running it, The side panel was taken off so I can see if anything bad happens while it runs. So it couldn't have been overheating. Any suggestions to avoid the overloading when I have the GPU installed?

 

Edit: I DO have a Chipset that came with the computer, But I know for sure that it wasnt optional since I didnt need to manually put it in because it was already installed in the computer.

Sorry, I meant those cards were available as a paid for optional extra.  They have an HP part number and are shown in the parts map document below.  The basic system uses Intel integrated graphics (model GMA4500). 

 

Where a cooling system has been designed to, for example, draw cool air in through the front, and exhaust hot air through the back, removing the side panel could actually negatively affect the cooling of some components.

 

Here's some documents I found that may be helpful.

 

HP Enterprise Power Supply Architecture (information about proprietary HP power supplies) - http://h10032.www1.hp.com/ctg/Manual/c02076124

HP Elite 8000 Series Technical Reference Guide - http://h10032.www1.hp.com/ctg/Manual/c01960471

HP Elite 8000 SFF Parts Map (parts diagram and part numbers) - http://h10032.www1.hp.com/ctg/Manual/c01944842

 

The second document includes a pin diagram for the power supplies for the Elite 8000 SFF (small form factor) & CMT (convertible mini tower) model on page 7-2.  This is interesting because the wiring for the two models is shown to be the same. The CMT version came with a 320w PSU...

 

The 320w power supply part number for the CMT version is 508154-001. The part number for the SFF power supply is 508151-001.  Your pictures show therefore that the 320w PSU you bought, is the CMT version, and at least according to the wiring diagram it should work, although obviously not fit in the case...  My suspicion then is that the PSU may be defective...

Oh? Well thanks for the heads up! Here I go thinking theres something wrong with my COMPUTER. So I should get a refund and get a fresh PSU if my retailer gave me a faulty one. Thanks man :)
