Hey, thank you for the merit @ZimbaCardi

I am not a electronic specialist like many here, but I think is not very good idea to connect conventional Psu to B1.
User NotFuzzyWarm already talked about that
DO pay close attention to the power specs for this! The miner CANNOT use a normal PSU. It requires 2 different voltage inputs, one for the control board and a higher voltage one for the hash boards.
From their site:
3. If the voltage for the miners control board doesnt range from 10.8V to 13.2V and the voltage for the hash boards doesnt range from 14.5V to 15.5V, the miner may fail to work or even breaks.
If you look at their PSU for the miner it is dual voltage out...
It seems it is very difficult to find a replacement for B1's Psu.
Rabinovich also talked about other Asic that uses 14-15v PSU. Innosilicon T2.
Maybe this Psu can work with B1?

I will keep searching.
