if you have a dead PSU, please PM this account with your Bitmaintech.com OrderID and what happened to the PSU, please take some photos with your username on it.

Questions regarding using a different PSU while the original PSU is dead. Yes as long as it is a strong enough PSU, you can do so with your own risk.

S4 is designed specific with this PSU, so if you use any other PSU, please consider how much watt each line would pull and power cord gauge) If you modify PSU to fit with the connectors on S4, it could be hazardous to splice the wire without a proper process and it may create a fire hazard or electrical shock hazard.
