The purple wire on a standard 24-pin ATX connector provides a standby +5V power supply, rated in the spec for up to 50mA but in reality today often supporting close to 1A. This is more than enough to run the motherboard standby power as well as a Raspberry Pi. This has the added bennefit of working just like a real BMC: when the system is unplugged, the BMC also turns off, and turns back on as soon as power is reapplied. With that in mind, I made a simple "adapter" out of a piece of solid-core CAT5 cable, which is inserted directly into the ATX motherboard connector, with the other end attached to a standard MicroUSB cable. The result is consistent, reliable, in-case power for the BMC without any trickery.
