PSU for 7970 crossfire.....

Briggsy · #1 10-04-12, 01:44 AM

Hi All,

I'm just about to buy a second 7970 to run in crossfire, will my PSU (below) be enough to run this and with an overclocked 2700K @ 4.7?

Please could you check my current setup (below) and see if there could be any issues with this new addition?

Thanks

Well the quoted website recommends 877W as standard for an overclocked gaming rig in crossfire, I will be adding a water cooling loop in soon so I guess I should upgrade to a 1000/1200w....

Any recommendations?

Thanks

Yes mate the AX1200 from Corsair will fullfill your needs nicely!

AX850 would be more than enough.

I was gonna say, a quality 850+ watt.

750w I just wouldn't be happy for 24/7 use and overclocking. Testing - I'd probably give it a go if it was a good one.
