I am running (3) 7950's @1050/1450 @ 1.125 V on a 750w Rosewill 80plus Gold and no problems so far, I am aware of the risks of pushing the limits of a PSU. I am getting 608kh from each card, cgminer 3.1.0, -I 20 -w 256 -v 1 --thread-concurrency 21712
This has been a very stable 1.8Mh system. Open air system, small house fans on cards, 71c temps.
ha, that's good to know.
Now I can switch my 3*7950s to the HX850 and leave the 1000w for 3*7970s
BTW, is Antec 1000 Platinum enough to run 3*7970? (not GHz edition)
