Ok I have another issue with another rig. This one has 6 290's. 4 being powered by a lepa 1600w, working perfectly. The other 2 is plugged into 850w PSU. But when the two that are plugged into the 850w psu starting mining it freezes the rig and eventually crash when i start cgminer with either of them. 1 by 1 or both together or all 6. It's weird really not sure. both PSU are hooked up by add2psu.
