Pc resets itself help.

So I wondered if someone could help, for some reason my PC has started resetting for no reason, the PC will be on and then out of nowhere it will turn off and then come back on, or even some days I will press the power button and it will just cycle like the video.

Specs are
i5 4670k on a Msi z97 gaming 7 motherboard, Corsair Vengeance 32 GB DDR3
1080ti ran by a P850GM Gigabyte CPU.

i have tried using another PSU Corsair CX650 and at first it seemed to work fine but then the issues started again, but I don't know if that was because it wasn't as powerful as the 850.

Yeah that sounds like psu
Make sure all the power cables
Are totally inserted
In motherboard and gpu
Had it in the past with 24 pin connector
The motherboard was flexing downward
As I put it in
So it didn't fully latch home
650w should be enough

Will retry the corsair 650 tomorrow to see if its that.
