PC Crashing. Faulty PSU or underpowered UPS?

[TRNQUL]

Hey guys. So my PC crashes randomly on it's own. Sometimes its once in two weeks, sometimes 5 times a day. It just turns off as if a power cut and turns back on.

My PSU is a Cooler Master 650W and I've also attached my full specs. I have my PC plugged into a brand new 1000VA/600W UPS. Even with just the PC on it, it shouldn't be more than 450 watts. If I plug the CPU directly into the wall, the crashes reduce a bit. Is it a faulty PSU or the UPS is not able to take the load? (Even though the PC should be pulling around 400 watts while the UPS is 600)

Plenty of power , just a poor quality PSU.

Some PSUs and UPSes just don't go along but since you're saying that you're still experiencing crashes with PC plugged into the outlet directly that's probably not the only issue here. This PSU isn't very bad but it's old so it might be a good idea to replace it anyway. Other than that it may be CPU/RAM/GPU instability. Try to revert any OC to stock settings.

Actually 99% of the time the PC doesn't crash when plugged I to the wall. Even with my old UPS, it was working fine for 2 years. Then it started crashing so I bought a new (current) UPS. But it still crashes on the UPS and almost never on the wall 

I don't have any OC at the moment, only XMP. But that too was enabled after all these crashes started. All my Temps are safe as well.

Disable it 

It could be unstable 

If you want run memtest86 and OCCT to make sure that at least xmp is not the cause of this

I have an I7-6700, 16Gb fury Hyperx 2133Mhz, xfx Vega64(FE) and same issue, pc crashes on load.
I also tried to put inside an other card(R7-240, kept the vega64 inside for load test) when the GPU crash happens, I saw almost no difference, except it was crashed way faster, and the screen was intact, but the system was frozen, in the other way the pc signal was lost.
