Got the power supply and have hooked it up and the system is under test. Thankfully, nothing was blown except the power supply.
Here are comparison photos between the old and new power supplies. The 850Watt Focus and the 1000Watt Prime. Same manufacturer and both fully modular so that the cables could just be re-plugged into the new supply. Worked like a charm. Back up in about 30 minutes. No cables to replace or re-route.
