ATX12VO is a new power standard from Intel, which only provides 12V power input to the motherboard, and removes 5V and 3V3 power inputs, also shrinking the motherboard power connector to 10 pins from the previous 24. This simplifies the power supply designs, reduces wire losses and makes them more efficient. Given Z180's power consumption, a two-phase switching regulator design would be more than enough.
