No thats not enough, I blew my cp-850 with i7 950 and gtx 470's. Hmmm well check this one, this is what I would really get:

NCIX.com - Buy Corsair Professional HX1000W 1000W ATX 12V 80A 24PIN ATX Modular Power Supply Active PFC 140MM Fan - Corsair - CMPSU-1000HX - in Canada

And if you wanna save some money and go with quad rails, instead of a single 12v rail then try this:

NCIX.com - Buy Enermax ERV1020EWT REVOLUTION85+ 1020W ATX12V 24PIN & PCI-E Power Supply - ENERMAX - ERV1020EWT - in Canada

If you don't care about you hardware and you really wish they die fast then you got yourself a 1000 watt powersupply under a 100:

NCIX.com - Buy OCZ B-Stock Refurb Elitexstream 1000W ATX12V 24PIN ATX SLI Ready Power Supply 120MM Fan Black - OCZ Technology - OCZ1000EXS-B - in Canada
