PSU 850w PSU enough for Crossfire?

Hi,

Simple question really. At the moment I have an Enermax Revolution 850w, is this enough to run 2x 5870 in crossfire or would I need to upgrade to do that?

Thanks

 

Would be enough matey.

Obviousy need 4x 6 pins though or 2x 6 2x 8 (that aso work as 6 ike on aot of psu)

 

850W would do the job fine.

 

Thanks, good to know my lack of planning ahead won't cost me

 

even my Hx620w is not breaking a sweat doing 5870 + gtx260. (both rated at around 180w) so your 850 will be more than perfectly fine.

 

Quick question wuyanxu - I have the same PSU, but it only has 2x PCI-E connectors. Do you just use the molex to PCI-E adaptors to power the additional card?

 

That's what I do on my 2 * 8800GT's one from the PSU the other via Molex adapter. Works fine!

 

does this answer your question?




not ideal, but good enough for a few days to test out hybrid PhysX

 

Yes I do get the idea
