The ATX12VO power standard is a new specification for desktop power supplies which boasts greatly increased efficiency over regular desktop power supplies. The new standard requires a compatible motherboard with a 10-pin power connector along with a compatible power supply which only features 12 V rails. The standard requires that any voltage conversion above or below 12 V must be performed directly on the motherboard which increases the complexity and cost for motherboard manufacturers. Intel is interested in promoting the standard with their upcoming 600-series motherboards for Alder Lake-S however most enthusiast boards are unlikely to feature the standard. The standard may find higher adoption with entry-level motherboards for system integrators and pre-built suppliers who need to meet strict government power efficiency regulations.
