Think of the typical US car. If you drive it at 120 MPH it will need repair soon. Not so much at 65. Same idea for PSUs. I can't find PC details so I can't give a nod to this or that.
Hi I was recently playing CSGO and when I was in the middle of playing my computer turned off completely. I waited a few minutes and tried to turn it back on and it did not turn back on, so I unplugged the power waited a little, i hit the power button with it unplugged then I switched which outlet the power unit was plugged into and tried to turn back on my computer and it turned back on. My Psu and cpu is about 3 years old, I cleaned out my cpu and put a new cooler in there that has thermal paste and seems to be working, 22-28c in idle on motherboard. I also put in a new graphics card with a 8 pin connector. So do you think that my Psu died? I have the EVGA supernova NEX 750b. I appreciate any help thanks. it is not just Csgo it's whenever my computer is under a nice amount of load it shuts down, I did a small 3dmark test and walked away and came back and my pc was turned off, i tried to turn it back on and it did not turn back on until i switched the psu off and on, do you think my psu could be causing my pc to shut down during load?
