ATX 3.0 is a desktop Power Supply Design Guide that Intel updated in 2022, in which new versions of design specifications such as CPU 12V current configuration and Peak Load requirements are included.

If the gaming system is not equipped with a standalone graphics card, it will have no impact.
If it is equipped with the new specification PCIe Gen 5, new optional power needs to be purchased that can provide a new version of PCIe 12VHPWR cable and a design that allows instantaneous power to reach up to 200%.

1. FSP had started laying out and did R&D on PCIe Gen 5 powers since 2020-2021, and is now manufacturing PCIe Gen 5 power supply.
2. FSP has launched its PCIe Gen 5 power supply in Q4 of 2022. All products to comply with Intel PSDG ATX 3.0 and 12VO 2.0 specifications. Power supplies grater than 450W meet Peak Load 200% design. Power supplies less than or equal to 450W meet Peak Load 150% design. New version of PCIe 12VHPWR cable plans to be included as a standard accessory with power supplies with 750W (included) or above. For power supplies less than 750W, it will be configured according to customer’s requirements.
