It depends, I'm using an Enermax 550 watt which is overkill for my system, but the plus side is it has a walk in the park powering all my hardware so never gets more than warm, even under load.
My cooling "radiator" is well up to absorbing any additional heat. My reason for wanting to watercool it is to be able to remove the fans not to gain any more performance.

The larger sink in my Enermax 550 watt is live 240v, but I still can't see why it needs to be, wish I could find a definate answer for this as it's holding the job up now
