Phanteks' highly desirable dual-motherboard case, the Enthoo Mini XL, was displayed with a new PSU power splitter accessory, at Computex. Simply put, this accessory lets you multiply the 24-pin ATX and 8-pin EPS connectors of your PSU, so you can run both the ATX and ITX motherboards with a single PSU, with the added freedom of shutting down and powering up either board without affecting the other. The splitter takes is 'smart' in this way. It takes 24-pin and 8-pin inputs from the real PSU, and to the end user, behaves like two PSUs, so both "systems" (motherboards) can be turned on or off at whim.
