user3029: I'm trying to repair a Bitmain Antminer S19 Hashing board. But how much voltage do I need to power this thing up for testing using a benchtop power supply?

user13866: Apparently the Antminer APW12 Power Supply for S19 provides 300 amps at 12-15 volts.

Note that just the Stand-By output (12 VSB) alone provides 20 amps.
I had a look to see how much a 300 amp benchtop power supply would cost - it seems to be starting around $5000. That's a lot more expensive than an APW12
Maybe a single board needs much less power but I suspect you need to consult the documentation for the S19.
