ATX 3.0 Power Supply New Specification

Since the previous generation of NVIDIA RTX 30 series Founders Edition graphics cards started using the 12VHPWR power supply interface, various power supply brands have been introducing products that comply with the Intel ATX 3.0 specification. But what exactly is ATX 3.0? And can you just use an adapter with 12VHPWR? Let’s find out.

The most significant aspect of ATX 3.0 is its emphasis on improving the requirements for power excursion, which refers to the instantaneous peak power consumption or power spike/peak power that is frequently discussed in the community. The issue of instantaneous peak power consumption has been a topic of discussion for a long time, beginning with the era of AMD VEGA graphics cards. Taiwanese players have been particularly concerned about this issue, with attention further intensifying with the launch of the previous generation of NVIDIA RTX 30 series graphics cards (as evidenced by related memes and jokes).

The PCIE CEM organization has indicated that the new generation of graphics cards in the future could experience POWER EXCURSION (100 microseconds) that achieves three times the continuous power level (1 second). However, Intel ultimately decided to mandate ATX 3.0 power supplies (for models that provide 12VHPWR connectors), with a requirement to provide twice the overall rated power in a very short period of time (100μs). According to STEPHEN EASTMAN, this decision was made after extensive discussions with various power supply manufacturers, which revealed that twice the overall rated power is a more cost-effective option.

In summary, if a power supply features 12VHPWR power supply wires, it must comply with the ATX 3.0 specification. Power supply models with ratings less than or equal to 450W must deliver 1.5 times the overall rated power within 100μs (microseconds), while models with ratings greater than 450W must deliver 2 times the overall rated power within the same timeframe to be certified as ATX 3.0 compliant.

The ATX 3.0 Design Guide stipulates that power supplies with ratings exceeding 450W and featuring 12VHPWR cables must meet the 100μs 200% requirement for instantaneous peak power consumption.
