Could my PSU be failing?

[Calvinb81]

My monitors randomly go black or any random colour when I start to put my computer under load, it is definatley not temps of anything I have monitored them all so what could it be? After the screens go whatever colour they choose I have to restart the PC and it doesn't properly turn on afterwards. All the fans spin up but the hdds don't, no power goes to my peripherals and the monitors don't turn on either.

I have updated all my bios, drivers, reseated everything, dusted everything idk what else to do. I don't have any spare components to test my PC with but I am thinking it may either be the PSU or GPU? I have only had the PSU for 6-7 months now but I heard the cx weren't the best


SPECS:

I5 2500K @ 4.2
Msi p67-g45
8GB gdd3 ram
7970 xfx DD @ 1000/1500
Corsair cxm 600w
256gb crucial m4
500gb hdd
1tb hdd

Being that Corsair CXM 600 watt power supplies aren't the greatest quality , that would be my first guess.

Hi yes this is my second one, my first one was the same model but that lasted about 2 years.

It literally only happens fast when im in a game that is using my GPU a lot, i have played eu4 for 2-3 hours with no problems.

BUT in the time that it does work i see no other problems with, no artifacts or anything which is making me think that the GPU is in 100% working condition so it must be the PSU.

Could I get your opinion on the Cooler Master RS650?

The only good Cooler Masters are the V series.
