Henry Chinaski :
Corsair, Antec, Seasonic and Enermax are the best for me.
I'd say the exact same. Seasonic is the oem that Corsair has contracted and both are really high grade power supplies.
Haven't had any problem with Antec power supplies either, and never tried enermax
Thermaltake's okay, but not 'quality' - they're a bit like coolermaster and ocz - I'd call all these three upper midrange. I would stay away from ocz supplies though as I've had some bad experiences with poor or absent noise management. They've got great tech support though - but so does corsair.
my favorite pick : corsair
Used em in all my builds since 2007 (mostly VX supplies, only two modular ones) and haven't had a single issue yet.
