That one isn't 10% off as it is not one of the "select" PSUs listed. This one is, though:
Newegg.com - OCZ ZS Series 650W 80PLUS Bronze High Performance Power Supply compatible with Intel Sandy Bridge Core i3 i5 i7 and AMD Phenom
$80 - 10% = $72 w/$20 MIR card, free shipping. It's not modular, though. There's none under it on the list that I would put in my computer.
Never count the rebate off the price when you are figuring costs. It's too easy to miss sending it in, or to do it wrong. That's why I will post the price and then the rebate... full disclosure. So the Corsair would be:
$95 - $10 (w/ promo code EMCJHJG54, ends 12/19) = $85 w/$15 MIR card, free shipping.
