Thanks - that is great information. I'll build it slowly, adding one card at a time and running it for 24 hrs before adding another one.
If wattage gets tight, I will dedicate the X-1250 for the GPU cards and get an 'average' PSU for the board\CPU\SSD, etc... I'll try using x1 -> x16 extenders w\molex (attached to the X-1250) if I end up using a dedicated PSU configuration.
Topic: Power Requirements for six (6) HD 5850s? (Read 375 times)
According to this article they recommend having 200 Watts per card.
So you would definitely want a least 1,200 watts give or take. You could try it with that power supply.

I'm designing a rig to run six Radeon HD 5850s. I got the GPUs dirt cheap and want to put them to use 
. I have a Seasonic X-1250 PSU and was wondering if that would support the entire rig? I plan on using a low-consumption MB\CPU with SSD drive to minimize outside power consumption. The MB I plan to use is a GIGABYTE GA-990FXA-UD5 (which I have already read on here can be used with six 5850s simultaneously).
Can someone fill me in on what wattage a 5850 card can pull when under heavy load? (and provide suggestions for clock speeds?)
Thanks in advance.
