Will this power supply be able to crossfire two HD 5850's?

Specs:
AMD x3 435 overclocked to 3.8ghz
Corsair 4gb 1600mhz ddr3
Samsung Spinpoint F3 500gb (going to add 1,2 more in the future)
MSI NF750-G55 motherboard
Antec 300 Case

Pulled from AMD

http://www.amd.com/us/products/desktop/graphics/ati-rad...

" 500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended (600 Watt and four 6-pin connectors for ATI CrossFireX™ technology in dual mode) "

Here is some actual power usage (note this is total system power usage, not only the cards, on i7/6GB RAM/Velociraptor), pulled from LegitReviews.



You'll be cutting it somewhat close but you should be fine.

Yea it should handle it but you will need adapters for the external power for the second card. Spend a bit more and get a PSU that has all the necessary connectors and does not cut it quite so close. If you have the money to spend on CF'd 5850's, don't cheap out on the PSU. I would recommend the Corsair TX750. Costs a bit more but better quality and has all the necessary connections without using adapters.
