Power Supply Module
The Source D'Energie is a power supply module designed to power up to a 6U case with +/-12v and 5v rails. Wall wart plugs can be used for a 3U case with few modules, but for anything more than that we recommend a 4A power supply. The Source D'Energie has two 16 pin headers, perfect for powering two rows of your system. LED's on the panel indicate the health of each rail at a glance

These merchants probably sell this module. Huh?
