This shot shows the Power Supply Unit (PSU) firmly seated in the chassis, alongside the installed motherboard and CPUs. The PSU is a SeaSonic M12D SS-750 which supports the ATX-offshoot specification called EPS12V (defined in the Server System Infrastructure specification) which is required to power the motherboard with three separate connectors as shown in the image: a 24-pin main connector, an 8-pin secondary connector, and a 4-pin tertiary connector. The PSU can support up to 750 Watts of maximum power, and combined with the chassis backplane, all twenty potential hard drive slots supported by Shinra's maximum physical capacity.
