My PSU is black. It says 850.. I thought it was supposed to be 1kw for these.. Im wondering if its adequate for overclocking to 325..

Splirow are you mining at 325mhz? Also what are your temps? My unit is in a 60deg F. room and im at 27/60/59

There is no reading for FAN 2, it just says zero, is that the case with yours as well?
