The ATX 3.0 and Gen 5.0 (12VHPWR) standard is designed to fully support net-generation CPUs and GPUs and tackle the 3x power spikes that the hardware would create. Since the announcement of the RTX 4090, people are really getting interested in the new standard and are looking for ATX 3.0 Gen 5.0 PSUs but Corsairs says they don’t have to.

According to Corsair, the new Nvidia 40 series graphics cards are already compatible with the currently available Corsair PSUs. The RTX 4090 uses the new 12+4 pin 12VHPWR power connector but all cards ship with a PCI-e 8-pin power to 12VHPWR adapter.

The following is what Corsair had to say regarding the ATX 3.0 standard:


There’s no need to wait for future PSUs to support Intel’s new ATX 3.0 standard and CORSAIR’s power supplies already provide the needed reliability and quality components to support the higher power needs of the next generation of PC hardware. Whether it’s an RM1000 that’s seen many builds, or a brand new HX1500i, you can depend on your CORSAIR PSU to power your graphics cards into the future.

Furthermore, customers can also order the official Corsair VHPWR 600W cables compatible with all Corsair type-4 PSUs. These connect directly to the PSU via the existing PSU-side connectors for unfettered power straight for your new graphics card without the need for a PCIe adapter. Sense wires are configured to 600W for 1200W rated Corsair PSUs and higher while they are limited to 450W for 1000W or higher PSUs and 300W for 750W or higher.

The official CORSAIR 12VHPWR 600W PSU cable is available to order immediately from the Corsair store. Orders will ship beginning September 29th.
