[SOLVED] Computer randomly shuts off

[MrZuzu]

Computer shuts off nearly immediately after turning on. It gets past the boot stage and up to the login to windows. If not immediately it happens within 2 mins of boot. If it gets past that 2 min mark of being on it’ll run fine for hours of hard gaming without any issues.
When this does happen. Ram and motherboard leds stay on. Although, gpu and case fans shut off. Power button does not shut off computer so have to turn off power point or back of tower.

Any advice or ideas would be appreciated.

Not a great PSU, but not a terrible one either. Could still be the issue but I wouldn't just say off hand that it is like I would if it was a known doorstop of a power supply.

I'd bench the whole thing and see what shakes out.

Update. Changed the PSU to a thermaltake 750. Issue has been resolved.

Right. That's about what I figured would happen, but always want to take you through the right steps first. Glad you got it sorted. Good luck.
