Re: Power supply

@T6DSquadYou're on the edge, but should probably be fine unless you overclock.

You can calculate the power usage here:

I made a simple calculation based on your hardware (and some minor assumptions), which gives me the recommended PSU wattage of 421W.

As for AIO vs Aircooling, I'd suggest AIO just because the easy installation and low noice. But don't be fooled. A high-end aircooler will be better than a low-end watercooler.
