would this psu be OverKill?

Haha that's what I was talking about too. If he's looking at a 1kW PSU, he probably doesn't care too much about saving the environment.

This logic is flawed.

A 500W 80% efficiency PSU and a 1000W 80% efficiency PSU will be equally as environmentally friendly. A PSU does not constantly draw it's maximum load. And almost all PSU's reach their rated efficiency at a very low power draw as well.

PSUs are most efficient when supplying ~75% of their rated power.
