PC constantly shuts off and attempts reboot

At this point in your troubleshooting, I have to agree with poorguy. Don't know if you're savvy on schematics and test-meters.

A common cause of motherboard issues or failure is bulged or blown capacitors. Check the top of each capacitor to see if it is bulging, even slightly, or if the capacitor is leaking, which is an indication the capacitor is blown. If you find any bulging or blown capacitors, that is very likely the cause of any motherboard issues in your computer. A decent large magnifying glass works wonders here! I have a stand version with illumination I use for inspection, removal & replacing components.

Alright thanks, I'll inspect the capacitors but it's going to take some time as my CPU cooler has to be removed in order to take the plastic shield that covers most of the motherboard.

Can you explain what plastic shield you're referring?

On ASUS's TUF brand of motherboards there is a plastic shield covering most of the surface of the board. I can't see all of the capacitors unless I remove the plastic shield.

Thanks.
As it's a quite new MB, don't think you have a bad capacitor.

You didn't answer: I see a i7-4770k. Did you overclock?

Being new or quite new doesn't mean it couldn't have a failed capacitor or any other component.

We have brand new motherboards that come with capacitor kits because the manufacturer used cheap crappy capacitors.

Theoretically one would think being new or quite new that it wouldn't have bad capacitors or any failing component.

I see brand new motherboards and brand new power supplies right out of the box that don't work.

The MB is a fist line ASUS that has fist line components.
I have also seen brand new motherboards right out of the box that don't work. But as I wrote, don't think you have a bad capacitor, although it can (remotely) be possible.

Agreed.
