What PSU do I need? [Crossfire + OC Setup]

post #1 of 22
Thread Starter 
Hello!

I'm having a question about my power supply, because I have ordered my second HD 7950 3GB OC card to make a crossfire setup.
I think I need to upgrade my psu too, but I'm not sure what psu. Can you guys help me out?

My Setup:

AMD FX-8150 overclocked to 4.4 GHz, but planning to make that 4.6/4.8 GHz soon,
2x AMD HD Radeon 7950 3GB OC Edition (Sapphire) -> CrossFire setup.
Corsair H100i Watercooler
2x 4GB 1866 MHz clocked to 1600 MHz
2x 8GB 1600 MHz clocked to 1600 MHz
Sabertooth 990FX Rev 1.0

I'm currently using a 600W Corsair 80 Bronze PSU.
Please tell me if i'm missing some information,

Thanks thumb.gif

EVGA G2 750w is about as good as they come, cheap too thumb.gif

You could maybe pull off a 650w psu unless you plan on overclocking smile.gif

Edit: Is the power supply you have a Corsiar CX by chance?

because CX series isn't the best choice in terms of quality PSU. Zambezi uses a ton of power also so I'd definitely grab that 750W G2.

Agree 100%, it's a very good option and could see you through a few builds!

Do you guys think it's possible to use the 600 watt for like a week until I order the other PSU?

Or can this cause damage to components?
