Up To 1200W PSU Recommended For Some RTX 4090s

With the recent release of the RTX 40 series graphics cards, PSU requirements are popping up and some 4090s are wanting a minimum of 1000w up to 1200w.

It is no surprise that the RTX 4090 will require a beefy power supply, following on from the 3090 Ti that recommended a 700w PSU. Some AIBs (add-in board) stick to Nvidia’s recommendation of 850w, yet some of them say that a minimum of 1000w or even 1200w is needed.

GeForce RTX 4090 PSU Wattage Requirements
Models Target Board Power Minimum PSU Wattage
Asus RTX 4090 ROG Strix OC Unknown 1000W
Aorus RTX 4090 Master Unknown 1000W
MSI RTX 4090 Suprim X, Suprim Liquid X Unknown 850W
PNY RTX 4090 Verto Epic-X 450W 850W
Zotac RTX 4090 AMP Extreme, Trinity 450W 1000W
Galax RTX 4090 SG, ST Unknown 850W
All Colorful RTX 4090 Models Unknown Unknown
Inno3D RTX 4090 X3 OC iChill Black Unknown 850W
Palit RTX 4090 GameRock OC 450W 1200W
Gainward RTX 4090 Phantom GS Unknown Unknown

As you can see in the graph above, the outlier is the Palit GameRock OC that is recommending a massive 1200w PSU. That is the biggest PSU requirement that any GPU company has issued so far. The only thing that would beat this is if you were to run the GTX 980 Ti in quad SLI, but then that is four cards compared to just a single one now wanting 1200w.

Palit did not say why they recommended a 1200W PSU, but it could be assumed that their test setup used a power hungry CPU such as an overclocked i9-12900K. So when shopping for your new Nvidia RTX 4090, keep in mind that you’ll need to spend a bit to upgrade your power supply to keep up with the demand.
