i decided to get the 525W enermax because i am interested in larrabee and want some reserve for it in case i want to get one. the rumors about its power consumption are a bit contradictory. some say it will be power efficient, some say it will take 300W. hopefully not! that would be too much... :p

by the way my previous computer was a very small shuttle barebone with a 220W power supply. it was crammed (gf6600gt, 2 hds, 1 dvd-burner,...) and worked fine.
