So my GPU died and I RMA'd it with BFG. I got the new one, which is a refurbished 8800GTXOC, and hooked it up.
As soon as I powered on the computer I got the Nvidia Power Warning message saying that my card was under powered and I needed to connect the extra cables to it and that it's performance had been scaled back so as not to damage my system blah blah blah.
Well, I didn't have this problem with the old card (reason for RMA was artifacting), so I'm a little curious about what's going on. I called BFG and they suggested I test the PSU to determine if it's underpowering the card or if the card is defective.
I'm using an FSP Epsilon 700W, 4 x 12v rails, 15A each, so I'm hesitant thinking that the problem lies there, but then again I don't have much experience with PSUs so it could just be old (it's 3 years old) and busted now.
Does anybody know of a good way to test the PSU? Are there any apps out that that can give me readings or do I just have to go into the BIOS and see what it says in there? That said, I'm not sure what voltages I should be looking at so if anyone has a tip, that would be great!
You did remember to plug the PCI-e power connector onto the video card correct ?? - without that plugged in the card will still get power from the PCI-e slot on the MOBO but not enough to run the card in 3d mode !! (if you did plug it in be sure that it is connected completly)
If you have an extra molex-6pin adapter try using one of the molex connectors instead of one of the 2 6 pins from your PSU (they might connect to a different +12V rail) - If that still doesn't work it could be a defective plug on the Refurbed video card that they didn't fix. Do you have access to another system you could try the card on ?
