Aw came late to this thread lol.
Great choice on the 400cx, I have one myself. I honestly don't really like the basiq 430w, I won one from the antec contest a while ago and some guy is buying it for $25 tomorrow afternoon. I don't see why Antec is so expensive, it's kinda like sony lol just a brand name nothing special. The 400cx beats it at everything:
-more connectors
-sleeved cables
-all black
-looks better
-cheaper
-it's corsair instead of antec
-it's smaller
-no ugly 80mm fan in back, just a big 120mm on top
-400cx is
powering my gtx260
-it's not from antec
-it's made by corsair
-yea that's right, corsair > antec X100
-did I mention that it's made by corsair?
There you have it, my nice list of why 400cx completely tramples over the basiq 430, backs up over it, and runs it over again
