I like to have plenty so i wanted to go somewhere near 650W.
Hi again - Yes, that will do. More than you need, but no harm (except to your wallet)in that,the PSU pulls only the power your components need from the wall.
In fact, if you don't mind the xtra cost, having more than you need (up to a point) should cause the PSU to run a little cooler & quieter as it
won't be working as hard, and the fan won't need to run as much.
