Title says it all.

Seasonic X-650
i5-3570k (@ 4.4)
MSI Z77A-GD65
4x4GB DDR3
1TB HDD
256GB SSD
1 PCIe soundcard
5 fans
(currently 1) 7870

Hardware secret is as reliable as Jonnyguru, and Seasnoic PSUs the tops out there. HD 7870 consumes around 140W at full gaming load, 2 of them in CF would consume around 300W, the other components include the CPU overclocked to the max won't reach 200W. You're more than fine.

But there's the power of the case fans and CPU too..... The I5-3570K draws up to 100W at load, and that's without an overclock.

Solution
More aggressive cards at CF , HardOCP test system included i7-2700K @4.8 GHz.
