Anyone know what OCP (Open Compute) power voltage is used by this servers ?, and it is likely I can use usual 12v or 48v power supply and screw it to its power wire inside ?, is that a good idea ?, by number two picture seems I can just screw a wire connector instead, and maybe can use standard HP server power supply through mining power breakout, what do you think ?, its Gigabyte T181-G20 GPU server, and its likely using 12v DC input, also Gigabyte manual doesn't specify whether its 12v version or 48v version, also what if I just guest using 12v battery then if not turn up goes to 24v battery before then goes to 48v battery if still not turn up ?
