this Antec Signature SG850 850W is my dream psu, it's expensive, but it's also one of the top psus in it's class, if not the top psu, just read some reviews, and no I don't mean Newegg reviews, I mean jonnyguru and [H]ard|OCP type reviews done by professionals...
That Antec is my dream PSU as well! A bit pricey, but worth it!!!!
