Title: Trying to run 2 PSU for Mining Rig Post by: dog2bert on March 17, 2013, 03:03:44 AM I have a 640Watt Corsair PSU and was getting low hash rates with my 7970 (around 300mh/s)
I have two other 7950's plugged into PCI-e x16 slots. The 7970 is on a x1 to x16. This worked with on PSU, but the 7970 got low hash rates. So I tried using another PSU to just power the 7970, but now it doesn't show up. The second PSU is jumped to run all the time |
