HD 5850 crossfire on 650wats

post #1 of 43
Thread Starter 
Hello OCN.

I just bought a second HD 5850 to crossfire with my current one. But I want to be sure if an Antec true Power 650wats can run them? I have 4HDDs 5 fans (One led) DVD burner and Some Leds. Everything else its on the sig rig.

Will my PSU be able to handle it ok?

Thanks

Easily. A good 500-550W could handle them.

Its possible but you'l be near maxing the unit out with a high CPU clock. I'd try running your i7 at stock if you try.

Yes. I was thinking to run stock while I get a newer one if its near the limit of the PSU. Anyways... Do you know how to check how much voltage is it comsuming? To be sure how much it comsumes and know if I really need a new PSU or not.

Easily.

Even with CPU and GPU's overclocked.

I think you should be fine. I doubt your system will use more than 600W under full load.

It will be very easy. The 650W TruePower New is a great unit.

AMD recommends a 600W peak-rated power supply to power a system that has two 5850s in it (proof). The 650W TruePower New is a continuous-rated unit which means it has a significantly larger capacity than any 600W peak-rated unit.

So yeah, you have tons of headroom.
It's a computer!
