Everytime I push a little bit for my graphics card, my pc simply crashes. Sometimes it wiil reeboot, other times it just turns off and on video output and i get the messes "Catalyst as found an error" and it "reloads" the video driver.
I've tried multiple driver versions, and tried in Windows 7 and Windows 10. Same results allways. Just 2 ou 3 seconds on furmark and it goes like that. Reading about this I found out that the problem could be on PSU, but i don't now how to "read" the values. The GPU is a MSI R7870 Twin Frozr III, and it run on full load (games like GTA ou Watch Dogs) @77º to 80º C, and idle @27º to 35º, so I don't think the problem would be overheating.

Here is the HWMonitor report of my System.
Can someone tell me if the problem could be PSU? Is the PSU faulty??
My PSU is a Nox Urano 600W
CPU: Phenom II 965BE (TDP 125W)
 
Solution
it sounds typical of PSU failing but that said it could be the age of the devices so not really sure you would be the only one to know really the age of all of it
