The company has published the ATX 3.0 specification, targeting desktop systems with PCIe 5.0 support. The upgrade was the largest in the industry since 2013. In addition, Intel has revised the specifications of the ATX12VO standard for motherboard and power supply manufacturers to improve the energy efficiency of computer hardware.
The main innovation of the specification will be the new 12-pin 12VHPW connector. It will supply up to 600W to PCI-Express 5.0 graphics cards. The plug will also transmit service signals to regulate the DC output voltage. For comparison, existing adapters from a pair of 8-pin connectors to a single 12-pin have a “bandwidth” of 450 watts.
“ATX 3.0 and ATX12VO 2.0-based power supplies ensure that anyone who wants the most stable, cost-optimized performance with maximum energy efficiency from their desktop PCs can do it, now and in the future,” said an Intel spokesperson. Stephen Eastman.
The ATX12VO 2.0 specification also adds the I_PSU% feature for desktops, previously introduced on mobile and server platforms. It provides improved power efficiency for small form factor (SFF) systems that cannot use larger power supplies like classic systems.
It is expected that the first video cards supporting the ATX 3.0 standard will be presented before the end of this year. Previously, the first ATX12VO-based desktop systems were introduced by MSI (Creator P100A and MPG Trident AS models).
