Newegg has a promo for the the new EVGA 650w p2 platinum psu. Great deal at $69 after a $10 promo code (EMCAXNK26) and a $20 rebate card. Even at $89 if you never get the rebate, this is still a pretty good deal for a full modular platinum psu with a 10 year warranty.
EVGA 650 p2$10 promo code expires 9/22 @ 11:59pm pst.
