hi, lately my custom build desktop, about 3 years old, parts bought from hardware versand in germany, has started randomly powering off, as in like the power plug has been removed, not shutting down.

I've never had any major problems with it but now its happening with this problem. Its completely random when it happens, sometimes its within a few minutes of boot, and some times it never happens in a few hours usage.

Does anyone here have any idea what might be wrong? Could it be the PSU dying? Its a corsair psu and Im pretty sure its nowhere near being overloaded.

Quick specs are:

Win 10
Corsair CX430 PSU
MSI Motherboard
XFX AMD GFX Card
AMD 6300 cpu

Also when it powers off, the power LED starts flashing if it helps. And also, the power LED on the back fan now seems to stay on all the time, even when the pc is powered off and switched off at the back. I dont remember it doing that before.

Thanks!
 
Solution
Definitely a faulty power supply. I recommend you replace it with one of the following brands: Antec, Seasonic, XFX, or a higher quality EVGA or Corsair.
