haru3173 :
My build so far is (these are not yet bought except for the ram and the gpu)
Nzxt phantom case
corsair hx 850w modular
2x 2 ripjaw ram
7870 radeon
(still looking for a motherboard)
(stock cpu fan or Ill probably buy a zalman cooler)
For your PSU, you don't need 850W, your build pulls at at most about 350W. You should change out the PSU for the
Rosewill Capstone 650W Gold-Certified for $60 and you'll still have amp room for CrossFire/SLI in the future.
For your motherboard, get the
Gigabyte Z97X-SLI, the best budget overclocking board that also supports CrossFire/SLI, SataExpress, SataM.2, and a Realtek ALC1150 audio codec only found on higher-end mobos.
Good luck on your build!
