Sounds like a PSU issue, would suggest testing with another PSU.

Other issues would be that a sector on the RAM is faulty. Would recommend running memtest to just make sure RAM is fine. Create a bootable drive with memtest on it and have a look what it says, make sure 2 tests passes before stopping the test. Sometimes when RAM heats up it can bomb out.

Testing the ram now will update you in a few minutes

Said no errors found so I'm guessing its the PSU

it's like just turns off like a power cut then restarts like normal

Well while in Memtest RAM wont shut your PC off...so this indicates a overheating issue maybe on CPU or PSU is faulty.

the cpu is always under 50c

Then all points towards PSU.
