2x Amd 6950 crossfirex power supply requirements

I was thinking of getting a second GPU identical to my 1st one for a triple monitor setup, would my current PSU fit the bill?

Also, would that second GPU generate too much heat? (Currently running at around 70 degrees C on BF3 Ultra) Should I invest in a better CPU Cooler or something?

Here is my rig:

Current GPU: MSI Twin Frozor III Radeon HD 6950 2gb

PSU: Corsair TX850 (850W)

CPU: Intel Core i7-2600k OC'd to 4GHz w/ stock cooler

Motherboard: GIGABYTE GA-Z68A-D3H-B3

RAM: CORSAIR Vengeance 16GB (4 x 4GB)

HDD: Seagate Barracuda 1TB 7200 RPM

SSD: Corsair Force 3 60 GB

DVD Burner: Lite-On 24x

Case: Corsair Graphite 600T W/ 2 additional 120mm fans (room for 2 more)

  1. Yes
  2. your PSU is plenty. it would be wise to get a case fan or two to exhaust the added heat.


  3. From what I have seen in Crossfire with everything tweaked, the cards didn't hit 450w.

    And you will probably never hit FurMark loads, anyway.
  4. using HWmonitor and my ups to check,I'm drawing close to 700W with my setup.(BF3 ultra)

    I would also do more for case airflow,fans etc,my cards never get anywhere near 70'
