I have a 7970 and a 5870 in the same rig powered by a 600 Watt Corsair PSU.

The 5870 when in a separate rig get nearly 400 kh/s but when alongside the 7970 it on gets 230 and I cannot push the aggression past 12, even if the 7970 is not mining either.

Is this due to lack of power to the card, a driver problem or something else?

Thanks to all those that can help me.
