which psu is best for my setup?

post #1 of 12
Thread Starter 

Hey guys, I was wondering which psu would be better for a system that has two radeon hd6950's (unlocked shaders and overclocked to 6970) in crossfire setup and a i5-2500k cpu with a moderate overclock.

I would personally go with the Corsair PSU. XFX isn't a bad company, but Corsair is pretty solid in just about everything. Plus their warranty/replacement service is amazing.

I would pick the Corsair for the same reasons mentioned above: solid products and excellent customer service. From a technical point of view the PSUs are very similar.

Do you think a 650w is enough? JW cause im running a single 6950 on a 650w and not having to get a new PSU sounds awsome!

650w is enough! But you could go 750 for headroom, but you should be fine with a quality 650w!

I'd get either of the XFX units over the Corsair. They're slightly better, they're modular, and they're cheaper.

Oh i just noticed something. The xfx units have 4 pci-e connectors whereas the corsair units only have 2??

If I'm not mistaken a 6950 CF setup would take 4 connectors right?

Can anyone confirm this as I could be wrong about the corsair unit.

Those XFX XXX units are great..just did a rebuild with the 850 unit, and it wow'ed me big time.

Highly recommended.

Edit: Yes you will need 4 PCI-E connectors.
