Topic: Required PSU for a 5850 and a 6870 combined (Read 647 times)
Aint you able to try without the riser?
still cant get er going, second card just refuses to boot, i guess the last option is the riser doesnt work but i bought it brand new so i am thinking it has to be something else
because both cards work on idividual boots, both fans run when booted together but only my primary, 6870, will boot with both and i cant switch the setup cause the riser wont fix under the 5850, guess my options would be try a new riser or get a new mobo?

Okay well i think im going to shut er down and try to get the dual card setup going again and ill post back with any issues
750 is more than enough! I'd say you would be fine with 500-600W if you let the CPU "idle" (aka. not mining).
I'm running a Dual CPU Quad core (mining FTC = total 7 active cores), 1x5870 (mining LTC) and 1x6450 (also mining LTC). This under a 600W PSU without any problems.

I have a seasonic gold 750w psu and from what i understand the 500W is good ennough for a 5850 and the 6870 only needs 150w so my 750 should be good?
I can get both cards to run individually but when I try to boot the secondary card on a powered 1:16 riser nothing happens ans it wont boot and the only conclusion that I cna come to is psu issues
