I have not received a response from BITMAIN support in over 48 hours.
Will be answered soon, and / or Tim will expedite it.
In my email, I apologized for getting so upset
Thats not a problem, won't affect anything.
you're going to need to do an RMA to replace the PSU for the second time
From what you suggested before, it didn't sound like a PSU issue as your non Bitmain PSU was also not able to power the miner, correct? If you're in the US then BitmainWarranty can do a unit swap for you.
