Which PSU and how many Watts?

Hey, so far i have the following:

CPU: Intel i5-3570k

Cooler: Coolermaster Hyper 212 EVO

GPU: HIS HD 7950

Mobo: Asrock Z77 Extreme 4

RAM: 8Gb G.Skill Ares 1600MHz (2x4Gb)

HDD: Seagate Barracuda 1Tb

DVD: Samsung 22x DVD-RW

Case: BitFenix Raider

Currently looking at these PSU's,

Silverstone Strider Plus 600w,

Antec TruePower 650w,

Antec High Current Gamer 620w (modular version),

Seasonic S12II 620w, (i know its not modular, but if it's really good then...)

Suggestions from this site plz thankyou:


Other info: Looking to overclock GPU and Cpu (not massive overclocks). Might Go Crossfire in the future with another 7950. Would prefer Modular/semi-modular.

More about which watts
  1. Antec HCG!

    Heck, anything from there would work! :)
  2. So is the 620w enough even if i go crossfire in the future
  3. You'd want at least 750W for that setup, unfortunately the PSU's you listed don't have enough PCIE connectors for CF 7950.
  4. any recommendations then?
