Is this a PSU problem?

[fb20]

Hi Guys!
Sometimes my pc restarts without any foreshadow and before it could boot up, it restarts again, and so on. I have to shut it down with the PSU on/off switch and wait about for an hour to turn it on. It happens when im gaming, or wathcing hd things, so if my pc is stressed, but my cpu temp seems to be good. My GTX275 vga runs at 80-95°C. When this restart happens i cant even touch the top of my computer at the PSU, its so hot. I'm wondering if that is my psu or my vga which causes the restart. My PSU is a Chieftec GPS-550ab-a, bought it about 2 years ago.

Thanks in advance

you have any other vga card to test with? those temps are a bit too high for the gtx card

You can't physically touch the computer case in the area where the PSU is... and you have to ask if that's the problem?

Yes, yes the PSU is toast... it fact it is probably hot enough to make toast.

I'm actually surprised a Chieftec PSU lasted as long as 2 years.

yes thats the strange thing for me too, because im looking forward to buy a whole new pc, except the psu which would be good for my new gear. but it looks like i have to buy a new one then

Cheap power supplies cause a variety of problems. I do think this is the cause of the issue, can you test with another power supply?
