Has anyone experienced problems running 650 mhz and up on the standard bitmain provided awp3 psu? The 1370 watt drawn at 650 mhz seems disturbingly close to the 1600w max on the psu since 1600 x 0,8 = 1280.
zeric, perhaps others will provide some input. I tested on APW7 and APW3s, both at 240V. I also considered the "80 percent" rule -- in fact, higher overclocks, if possible, may require the APW7 as you have pointed out. In my particular environment I monitored equipment with a thermal imaging camera and never found the APW3 to be outside of what I would have been worried about.
Are you experiencing problems, or just a question of concern? Regardless, I think this is an excellent question.
