PC restarts under heavy load

[Vencam]

My pc has started restarting itself every time i put it under stress (100% CPU, over 60% RAM used, or when gaiming heavy titles). It works just like a heating issue, if the pc has been off for some minutes, it works for up to 15 minutes before restarting, then it just will nearly ass soon as i lunch a game. But i'm sure it's not. Checking with SpeedFan, all my temperatures never reach 50 C exept for the CPU socket at 126, but i'm sure it's a fake temp, 'couse i checked the motherboard phisiccally and nearly didn't feel ANY heat on the socket. Maybe a virus? I know i could have some. Started 3 days ago, but i'm already desperate! HELP!!!

i5-4670K; GTX 770 OC; CORSAIR 700W bronze PLUS (don't remember the model). Got a CNPS12X by Zalman on the CPU and a HAFX by Cooler Master with 6 fans on it for cooling.

You need to get the power supply brand, model and capacity. We all think thats where your problem is.

Corsair 750 CX
Answering to you, "corndog1836", 1)No, i never overclocked the CPU nor the GPU
2) As i said in the question, it happens at about 75% of averoll max usage, or when i use at full any component (RAM, CPU or GPU).
Still, it's weird that it happens only after some minutes if pc was off for a while. Happens on program launh or resources usage nearly immediatly right after restart or prolonged use.

The CX units are not very good.

I would change the PSU for a proper unit.

No bluescreen right? Just shut off?

how old is the psu? Do you just power off or crash to bsod?

 

[Vencam]

The PSU is 2 years old.
When it crashes, it's just black screen and boot. While the black screen occurs, the audio still gets riproduced for 1-2 seconds, then the boot sequence begins. No fan interruptions, sometimes they even go faster for some seconds.

seasonic is great. I have one.... run virus scan just to be sure tho with kaspesky,Norton,MacAfee etc...

 

[Vencam]

Why would that be? I know Corsair is pretty reliable, and the power should be nearly twice as the needed! In any case, can i get a new one with he warranty? I mean, is this kind of issues covered?

 

[tiny voices]

The CX units are not good. They are made by CWT with junk capacitors. Corsair =/= quality. They have SOME great units and MANY poor ones.

You do not want a new cx750. You want a different PSU as a new cx750 will just do the same thing as it is poor quality.

http://www.hardocp.com/article/2015/01/21/corsair_cx750_750w_power_supply_review/9#.VXUKaYyg2Uk Not a good unit at all.

Thanks to all for your support!! I'm not drowning in doubts anymore.
