Should have told us, cuz there are two things wrong with that build. One, 650W is only needed if you CF that GPU, and that is only for extra extra headroom. You really only need 550W to CF/SLI and a 450W for a single 6670. Could have gotten the XFX 450W or Corsair VX450.
That motherboard is too expensive for your needs. Could have gotten away with a motherboard for half the price.
What The build list doesn't show is the other four storage drives, the efficiency curve of the PS, or the level of OC I'll run. Having plenty of power headroom was planned.
I know I could have stuck with the UD5H or P8Z77-V and met my requirements, but the Deluxe offers me dual LAN, BT 4.0, a better power stage, more room for expansion (more PCIe lanes), and no stupid legacy ports on the IO. I actually struggled for a long time with mobo choice. To the point that I had to make a spreadsheet to help...
