ATX 3.1 PSU List in 2024 [PCIe 5.1 Compliant with 12V-2×6 Connector]

Last Updated: Hardware No Comments

ATX 3.1 is the latest standard or specification for PC Power Supplies. It comes with various improvements in the power delivery department and addresses the issues that were causing the melting of the 12VHPWR 16-pin connector, particularly at the graphics card’s end. In the latest ATX 3.1 PSU specifications, the 12VHPWR 16-pin is replaced by the new 12V-2×6 16-pin connector. The newer 12V-2×6 16-pin connector has slightly shorter sideband signal or sense pins and slightly longer power pins. Also, if the two sideband signal pins SENSE0/SENSE1 are not plugged in properly and remain open, power will not flow to the graphics card from the PSU through the 12V-2×6 16-pin connector. These provisions have been made to ensure that the 12V-2×6 16-pin connector is plugged in properly into the graphics card (and PSU) to prevent melting of the 16-pin connector from causing damage to the graphics card.

Whether you need an ATX 3.0 or ATX 3.1 compliant PSU depends on the graphics card you have and also on your budget and personal choice. However, if you have an Nvidia GeForce RTX 40 series graphics card with a 12VHPWR connector or want to future-proof your PC for upcoming PCIe 5.0 or PCIe 5.1 graphics cards then you can get an ATX 3.0 or ATX 3.1 Ready PSU. Here also, if you have no budget issues and want to get your hands on the latest tech then I would suggest getting an ATX 3.1 PSU because the 12VHPWR connector is now depreciated and from now on, all new power supplies and graphics cards should use the new 12V-2×6 connector only. Right now, you can find a decent number of ATX 3.0-ready PSUs in the market from different manufacturers but there are only a few ATX 3.1 PSU models available, and that too with limited availability. So, to help you with this, I am listing some of the good ATX 3.1 power supplies from top manufacturers or brands.

Note: 12V-2×6 Connector is backward compatible with ATX 3.0 power supplies having 12VHPWR connector/cable. It means if your graphics card has the new 12V-2×6 connector but your power supply has the older 12VHPWR connector/cable, your graphics card should run fine without any issues. Also, the 12VHPWR connector should work fine with ATX 3.1 power supplies with a 12V-2×6 connector/cable.
