As mentioned, the menu system could do with a running total, or a least a +X / -X so you could assess how much it would cost to move a component up a notch.
There are plenty of worse choices than FSP, or are there?
MADSHRIMPS - Hardware Reviews ,Crazy Projects, Modding Tutorials and Overclocking - reading this review, FSP Epsilon 900 vs Silverstone DA750.
OOh, those heatsinks look rather small for a 900W
I think they misinterpreted the ratings, counting the FSP900 as being only 700W combined 12V (875 - 175), when it appears to actually be 840W (combined 70A) with an 875W combined +V rail rating.
Not a great test though, I'd like to see it given a 100% pounding, those heatsinks look mighty small, even given 80-plus efficiency
