My build will be asus p6t deluxe v2, i7 920 with noctua u12p se, 2 sli 285s, hauppauge 1800 tv tuner, x-fi titanium sound card, 6 gb ocz 1600 plats, and 2 wd caviar black 1 tb in a cooler master cosmos 1000 with 5 scythe slipstreams controlled by a NZXT Sentry LX Aluminum fan controller. Monitor is a samsung toc t240 in addition to a z-5500 setup if that matters. So is a Corsair 850 enough power for this rig? Thanks.
