Intel ATX 3.0 PC Power Supply Specification
19 years after publishing ATX2 power supply standard (a.k.a ATX12V2), Intel has released new ATX 3.0 Multi Rail Desktop Platform Power Supply specification. The main innovation in ATX 3.0 is new auxiliary 12VHPWR connector intended for next generation hardware, such as PCIe 5.0 desktop graphics cards. This connector can provide up to 600W on 12V bus directly to a graphic card. In addition, auxiliary "sideband" pins can communicate to the card the available power of PSU, and can also provide some communication back from the card to the PSU.
For the details of the new spec, pinout of 12VHPWR connector and designation of the sideband control signals, see our review of ATX 3.0 Connectors and Pinout.
