PSU for 3570k and HD7950 (OCed)


Looking to build a new rig, but I'm still unsure about which PSU to get. I will be overclocking the CPU and GPU sometime in the future and will not be using a second GPU.

System specs:
CPU - Intel Core i5 3570k
GPU - MSI R7950 Twin Frozr 3GD5/OC
RAM - Corsair Vengeance 8GB
HDD - Samsung 1TB 7200 RPM
SDD - Samsung 830 256GB

I've been reading a lot of good things about the XFX Pro 550Watt. Will this provide enough power when overclocking both CPU and GPU or would the Antec HCG-620W be the better choice?

  1. That XFX would be enough power, it usually good practice to try and buy more power than you'll need. For one it'll put less stress on the PSU, and you can still have room to add another card, or upgrade to something else later on. Those XFX units have 5 year warranty's too which is another reason I bought a huge one.
  2. Id suggest looking for a xfx Pro Core 650 W .

    7950 CF draw max 359W so 650W is enough !
  3. I recommend this one from Seasonic, I own it and its a great psu for the money.
