ATX12VO V3 standard shrinks the connector and maximizes power efficiency — new 8-pin connector also brings smarter power supply monitoring

Intel is set to release the ATX12VO V3 standard, enhancing power efficiency and introducing a smaller 8-pin connector for improved power supply monitoring. This revision aims to simplify power supply design, increase efficiency during low-power states, and offer new Low Power and High Power modes. The new standard will reduce connector sizes by up to 83%, making system layouts more compact and cost-effective. Additionally, support for PMBus communication and real-time power utilization data will enhance system monitoring and prevent power supply overload. Intel may announce the launch at the upcoming Computex 2026 expo.
