Question about XFX NVIDIA GeForce 8800 GT 512MB DDR3 PCI Express Graphics Card

2 Answers

I have a XFX Geforce 8800GTS that instantly shuts off the computer when I plug in the power connector into the card (even when the card isn't installed in the M Board). Tried another power connector and its the same thing, tried the card in another computer its the same thing, tried another card in my computer... it worked. So I took a look on the card and I noticed 1 of the capacitors (I think its the smd type that doesn't show the lined ventilation on the top) had a little bulging on the top of it, so I am suspecting that is the problem. So all excited I got my soldering kit and got all ready to remove it and get it replaced, only to look on the other side of the card to see that there's not really anything there to solder off. Now that leads to my question which is how to remove and replace a capacitor on the XFX Geforece 8800GTS

    Well the thing is that the computer won't turn on when its inside, so I was just merely diagnosing the problem. When I plugged out the power connector while the card is still installed and turn on the pc, it would give some very loud beeps, and when it power connector is plugged in the card and I try to turn the pc on, nothing happens, its as if I switched off the PSU. So that is why I took out the card, connected the power to it, turned on the pc... nothing, plugged out the card, turn on the pc, got video error beeps, and the moment I plug the power in, the system just shuts off and won't turn on until I plug the power out of the card, so I'm led to believe that its a power related problem... plus the damaged looking capacitor

Well, you're right about the vented cap shutting down the video card power, and no you didn't break anything and the rest is still good but I suspect this reply is too late for you... for anyone else who reads this, you can safely unsolder those SMT caps with a pair of low wattage controlled temp soldering irons. Heat both sides of the cap at the same time and use the irons like chopsticks to lift the cap. Its being tossed so heat the capacitor rather than the pwb pads. Be sure to use only enough heat to melt the solder and avoid softening the pwb so much you lift the pads. Its also possible to use one iron and alternate ends rocking the cap slightly until its loose, but its takes some practice with junk boards to do that without damaging the pwb pads. A professional rework station would direct hot air to preheat the area and then both sides of the component and lift it using a suction tip. Preheating isn't required in this instance, the component is isolated and not being reused, and without a fixture you'd have trouble handling a hot board.

This may be because your graphics card is not compatible with your motherboard, If you are using a newer Intel motherboard for example with Intel HD Graphics, there may be issues with using an older GeForce card with the board.

You can but a molex splitter so that you can plug the single molex you have into it and then have two, like a "Y". You will probably have to go online to a company like,, or who sell power supplys. I realize that means waiting a few days but the alternative is to either modify your PSU which voids the warranty or buy a different one. The splitter is inexpensive.

Gtx+ shorts out powersupply

1.Power supply doesn't have enough Amps for the 12 volt voltage rail.

2.Power supply doesn't have the required power cables/connectors required.
You NEED TWO 6-pin PCI Express power cables.
If you use just one, you will burn up the connectors down in the PCI Express x16 slot, and the power cable connection on the GTX card, and/or fry the power supply.

3.Cheap power supply that came in a deal when buying a computer case. Cheap case? Cheap power supply.

I installed the card on my motherboard, and it burns?

There seems to be some electrical problem with the card, or the way you connected it.

First of all, is your power supply a brand one (like Thermaltake) or a generic one? Generic power supplies do not work well with the better range of graphics cards since they don't provide a stable current.

However, if you say you smell burning plastic, the first thing I would look at is the way it's connected to the motherboard and the PSU. Did you attach all the extra connectors from the PSU to the graphics card? The card would have an extra power slot on the top (A 6-pin I think, I had two on my XFX 8800). Is it connected directly to the PSU, or did you use some sort of adapter to be able to plug it in? If you used some sort of 4-pin to 6-pin converter, this could very well be the cause of your problem. If your PSU does not have a 6-pin connector, it might just not be strong enough to handle this card.

If you couldn't find anything wrong with your power connectors, I would try installing the card on another computer and see if it fails there as well. Again, my guess is that your PSU is just not fit to handle that card, cause I haven't seen many 400W *good* PSUs in my life.

I just installed a geforce 6200 with heatsink, no fan, in my computer. Fry's is having a sale and for $20 after rebate, how could I go wrong? Upon first installation, the computer failed to boot.


Discovered modern computers will not even atempt to boot if the power supply is below the minimum requirement for the video card's recommended wattage. More proof that over-powered supplies are not an absolute necessity. I upgraded to 250w from the onboard 180w and it fired up. The rest was disabling the integrated video which i found out was compatible with geforce 5200 level of operations.

My system:
Dell Opti-plex GX260, cut to bare minimum since it was from a commercial business with 1G RAM after upgrade.

New Installation P5N32-E SLI

There is also a 4 pin power connector cable for the processor to connect onto the motherboard. Make sure that is plugged in. IF that still doesn't help, disconnect hard drive, video card, cd rom drive and floppy drive and any other pci cards in the system. Try booting it again at least to the bios. See if that helps.
