Try running some stress tests on your cpu and gpu (you can download them for free) This way you can watch the temps and wattage as the test is running. Also if it shuts down during one of the tests it will narrow down where the problem is. If it doesn't shut down ¯_(ツ)_/¯ sorry I tried. I have nothing after that. I'm sure you've googled the error code?
Yes, thank you for the support. It turned out to be the PSU. I'm going to give it a friend with a multi-meter and give it a test if its faulty, but i put an 850 in this sucker and its screaming now. No issues and i can start to OC now. I'm a happy camper.
