Intel releases the ATX 3.0 power supply spec

Intel has published the final ATX 3.0 power supply specification, and it’s the biggest PSU spec change in almost 20 years. PC hardware has changed a lot since then, particularly the power requirements of GPUs. ATX 3.0 PSUs will come to market throughout 2022.

The new standard formally introduces PCIe 5.0 graphics card support with a new 12-pin 12VHPWR connector that can deliver up to 600W. We’ve seen Nvidia release Founders Edition cards with 12-pin connectors, but they aren’t the same as an official PCIe 5.0 connector which include four additional sideband signals. The new connector is set to debut with Nvidia RTX-40 and AMD RDNA 3 cards.
