Had a problem with a new build and finally narrowed it down to either the R5870 being dead or the PSU not being powerful enough. Using 8800GT on the system = All ok, 5870 = beep codes.
Arctic 700W PSU
Box says you need 600W PSU so this one should be fine, however this PSU only supplies 1 x 6 pin which can convert to 8 pin but the GPU needs 2 x 8pin for maximum performance. The manual says 1x 6pin or 1x 8 pin should be fine but that's not the case.
Would I be better ordering a 4pin --> 8 pin converter or getting a completely new PSU? If so, could you recommend one which would work with this GPU?
Here's what the manual says:
"600W or greater power supply with one 150W 8-pin PCI Express power connector and one 75W 6-pin PCI Express power connector. (Recommend to use power supply with two 150W 8-pin PCI Express power connectors for best performance.)"
So I guess I'm looking for a PSU with 2x 150W 8-pin PCI E and a few 4pins for the cases 6 fans.

Thanks very much for the quick replies, I hope it is a simple case of the pins.
Yes Xaira, spot on. I was running with 1x 8 pin because the manual says it should work. But after looking over other sites on the R5870, they say, as you have said, that both 8 pin sockets need to be used.
