Well the Cooler Master makes a Silent series, corsairs are well built as well. I have been using a Corsair TX 750 and the only fans i heart are case fans and GPU fans, thats it. Corsair makes some pretty steady products, except for their cases. Not a fan of their cases
... and for that matter, XFX power supplies are also made by Seasonic, so go figure. I'd seriously just send this one back. For the $80-$100 it'd cost to buy a new 750W PSU of any quality, I'd be willing to live without my computer for a couple weeks or find another one I could use in the meantime.
