ATX 3.0 and ATX 3.1 are PSU design standards developed by Intel to improve compatibility with modern hardware.
ATX 3.0: Introduced support for PCIe 5.0 graphics cards and the 12VHPWR connector, designed for high transient power loads.
ATX 3.1: Updated the power specification with improved transient response requirements and introduced the newer 12V-2x6 connector, which provides better connection reliability and safety.
ATX 3.1 builds on the ATX 3.0 standard with improved connector design and updated power delivery requirements, providing better compatibility with the latest graphics cards.
