Hey guys, I have a S17+ miner thats been giving me grief for a few months now. The power supply started acting up a while back so I ordered a replacement but am seeing a new error where it only shows a value around .5 for voltage (needs to be closer to 21). This a brand new APW9 from bitmain directly, and the APW9 was the recommended PSU for the S17+. The old PSU I had would pass the voltage checks but then had problems detecting all the chains. Here's an example of the output:

Has anyone seen this before? Since it's a brand new PSU I'm not sure what I could do to fix this (and like I said I know my electricity setup works fine because this test would pass on the old PSU). Any suggestions on how to debug this issue?
