I'm setting up a PC with a Corsair HX1000i and an RM850 power supply to run three GPUs: one RTX 4090 and two RTX 3090s. I'm considering this power distribution: the HX1000i for the motherboard, a Ryzen 7600, and the RTX 4090, which should use around 600W, and the RM850 for the two undervolted RTX 3090s, which would total around 650W. I'm planning on using this system for local AI tasks and gaming with the RTX 4090. Does this setup sound good to you? I'm also using a dual PSU adapter to help manage the power distribution.

Using a dual PSU adapter is a good call! Keeping the RTX 4090 and the main components on the HX1000i is solid since it can handle the load. The RM850 should handle the undervolted RTX 3090s without an issue. Just ensure both PSUs are properly connected with the adapter, and you'll be all set!
Your proposed distribution looks logical. Just keep an eye on the total wattage—especially under load. As long as you're monitoring temperatures and voltages, you should have a stable system. Enjoy your build!
Thanks for the reassurance! I'll definitely keep an eye on those metrics.
Yeah, I agree! That setup seems efficient, and as long as your adapter is good, you shouldn't run into any power issues.
