PSU for Gigabyte RTX 4090 OC

[OverDrive]

Hi everyone,

I am considering the Gigabyte RTX 4090 OC. Gigabyte recommended a 1000w PSU for this card: https://www.gigabyte.com/Graphics-Card/GV-N4090GAMING-OC-24GD/sp#sp

However, only 850w is recommended for the FE and also the MSI Gaming Trio, although I know other AIBs also recommend 1000w. Given the very mild OC on this card and that I would only run it at stock, would my Seasonic Focus GX 850 (Gold) be sufficient? My current CPU is a 5800X3D.

Will happily upgrade the PSU if required, just wanted to get peoples thoughts/advice first though.

Thank you

I would just give it a go and see how it runs. The 5800X3D during gaming especially with the -30 offset is pretty low compared to other high end alternatives, so I would imagine there's enough headroom for the 4090.

sounds like it would be fine, can always undervolt/overclock the card yourself to get better power perf and not lose much fps

I've ordered a 4090 and I'm expecting it to be fine with a 125w cpu and a similar PSU. Might find out tomorrow if it turns up. My complete system power draw with a 3090 tops out at 550w while gaming with the GPU doing 350w.

Seasonic will provide their 12 pin cables for PSUs 850 and up (Focus new revision), so they seem to think it can handle it
