Best ATX v3.0 & PCIe 5.0 Ready PSUs Picks 2023 – Hardware Busters

I had to wait for today’s article till I had data on enough ATX v3.0 PSUs equipped with 12VHPWR connectors. Although none of today’s graphics cards has high enough power spikes to justify the tough ATX v3.0 requirements for power excursions, as it calls them, no one knows what the future GPUs will bring. You can read more on the ATX v3.0 specification in this article. We also have an English section in our discord server if you have any questions.

UPDATED 20 March 2023


There are two essential things that PSUs need to be added to our best picks to be available on the market and excel in terms of performance and reliability. Given their price tag, their build quality should also be the best possible.

As crazy as it sounds, because it is the highest capacity SFX unit, the Cooler Master V1100 SFX Platinum achieves the lowest noise output, followed by the SilverStone Extreme 850R Platinum. On the other hand, both Corsair units are noisy, especially the 1000W unit. Overall performance, the SF850L has a notable lead over the Thermaltake, Cooler Master, and SilverStone units. That said, it is not so fair to compare SFX and SFX-L units, but we do not live in a fair world! Lastly, in ATX v3.0 transient response, the SF1000L leads the pack on all tests.
