NVIDIA GeForce GTX 280 issue.

[Electrohead]

Hello people ,

i have some kind of problem with my GPU i noticed recently.
I downloaded furmark to run benchmark on my pc and check temp, fps, etc.
While performing test i noticed something weird, when GPU temp reaches (exactly) 73°C my fps are dropping and benchmark starts to run very choppy.

I get constant good FPS value during the benchmark but at 73°C it feels like my GPU is slowing down to prevent going over 73°C.
I've read on nvidia forum that gtx 280 cards can go way over 73°C and work fine so i guess temp is not the issue right ?

My PC specs:

Windows 7 Professional 32-bit
Nvidia GeForce Gigabyte GTX 280
AMD Phenom 9500 X4 2.2 GHz
3GB Samsung RAM memory (dual channel)
Motherboard: NVIDIA MCP61
PSU: http://tinypic.com/view.php?pic=29n6vjs&s=6

If there is any additional info i can provide just let me know.

PSU problem. Recommended 40A on the 12V rails while you have 32.

Thank You very much. Could You please give me some hint about what PSU should i look for ?

First, Furmark is putting your card under a stress that no other application will do so I wouldn't use it even for stability tests. If you have no problems in games and are on a tight budget you can still use that PSU but, since overall I don't think it's what you call a reliable PSU (I personally never heard of that brand and I bet it was cheap) and therefore might get you in trouble some time look for a Corsair TX650, SeaSonic S12II 620 or more budget friendly Corsair CX600.
