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.
