Alright, where to start with this one.
I recently picked up a BFG Geforce GTX 260 Maxcore OCX video card from newegg, and have had nothing but issues with it after putting it in, and have since fallen back to my Geforce 7950 GT. The symptoms of what was happening changed from Day 1 (yesterday) to Day 2 (today).
Yesterday I installed the new card and tried opening Warhammer Online to test it out only to find that the game stuttered on and off every minute or so (framerates were very smooth in between these hickups) and there was noticable artifacting that i could see when rotating my camera slowly near a body of water. I restarted and tried different drivers and now whenever the game gets to anything 3D that isn't pre-rendered it restarts my computer completely. No error, no bsod, no nothing. I reverted back to the old drivers and got the same issue. It was getting late so I went to bed and tried some more today.
I have read multiple forum posts with similar issues and tried most of what they suggested that I could do. I started with Memtest on my Ram, came back fine, so i swapped each stick out and put them in different slots. I looked at temps and the card idles at around 42 C and 55 C under load so i'm fairly certain that isn't the issue (as a note the card runs fine until I try to go into a game).
Lastly, I noticed power supply. I'm using an Ultra X3 1000-W Moodular power supply so I tried different PCI-E cables and tried all the available PCI-E slots in the PSU, but that didn't help either. One of the things that I couldn't try was voltage monitoring. I checked the readings in the bios and the 12V rail was coming in at 12.26v, which i'm really not sure if that's good or bad but since it's above 12 I assumed it's ok.
After all this i'm still left with the same problem. My 7950 GT works fine; however, the GTX 260 restarts my computer when put under load. This is when amp requirements caught my eye, which is leading me to believe that it may be my power supply. Prior to getting the GTX 260 I used a 9800 GX2 that would run fairly well but would occasional restart with no warning, similar to what happens now every time. That card requires 26a on the 12v rail. I sold that card to a friend and put in the GTX 260 which now restarts my computer every time I try to play Warhammer (it also happened in Bioshock although i was able to play for a few minutes). The required Amps on that card is a staggering 38a. Rewind to the 7950 GT which requires 18a and works just fine. I find this too be too much of a coincidence that as the required amperage on a card goes up, the problem seems to get more severe. Unfortunately, I don't have another power supply that can pump out 38a to test the card on.
According to my PSU it can put out up to 70a accross it's one 12v rail. This shouldn't be an issue, but im not too familiar with PSUs, so my main question is does this sound like a reasonable conclusion to come to? I'd read a little bit abot rippling and whatnot but i'm not sure what that really is or what it refers to. Is there anything else it might be that i'm just not thinking of? Any insight would be great because I don't want to pick up a different card only to find out I get the exact same problems as i'm getting now. Thanks in advance and sorry for the long-winded post!
