Could this be an overloaded PSU issue?

Alright, here's what happened. About 30 minutes ago i was playing IL2 1946 when suddenly for no reason my PC decided to shut down. No warnings, no blue screens, just shut completely off.

My current system is:
Athlon 64 x2 4800+ S939
2 gigs PC2700 ram
Geforce GTX 260 @620/2160 (factory overclocked)
one 400GB hard drive(had to move it into CD-drive bay and remove the hard drive to fit the GTX 260 into the case, doubt that is the problem)

Alright, before i had a X1900XT 512mb card, non OC'd. When i had it, I didn't get those random shut downs, except in Company of Heroes: Opposing Fronts, but that was the only game that happened in. On Tuesday night i was watching youtube videos when suddenly the X1900XT started artifacting on the screen, i dunno what happened but when i uninstalled the ATI drivers there was 4 green pillars going down the screen(http://img117.imageshack.us/my...?image=desktoprp2.png). Since it happened while i was on youtube i suspect the PSU might have killed the 1900XT, but i'm not for sure.

So i get the GTX 260 and replace the 1900, and the green lines are clear. I play games on it well. Today i play IL2 1946 for like 10 minutes or so and the forementioned shutdown occured. I am suspecting that the PSU is either overloaded or is going bad.

This is my PSU:

Should i get a new power supply?


 
Those PCP&C PSUs are pretty stout.
I'd suspect overheating of the CPU , but more likely the video card.
Have you looked at temps?
 
I just took a look and the GPU idles at 67C and i did like 2 one-minutes missions on IL2-1946 and it only went up to 73C.

Also i checked with Everest Home Edition, HW monitor, and Speedfan and they all indicated my 12v rail was at a 11.43-11.49V... same as with a previous PSU i had...

Would an Antec Earthwatts 650W PSU be a good replacement?
