Well I wasn't impressed with my Trio 550. Yes before you call me a n00b I know you need a DMM to properly judge but even with software monitoring, a good PSU should be rock solid on vcore and rails. The Trio couldn't even match my old Truepower 480 in that respect. So, i'm now the proud owner of a Silverstone Element 500w, rock solid so far and $20 less.
