Plus you'll save a buck. A buck you'll need to buy new GPUs these days.

You will have the option of connecting a GPU with a 12V-2x6 connector or one with up to 3x PCIe 8-Pin connectors.

Budget PSU for AMD RX 9070: CORSAIR CX750M

Looking for a PSU that is just right and does not come with full modularity? We got you covered. The CORSAIR CX750M with 80 PLUS Bronze efficiency rating will power your system in no time. It does not come with all the bells and whistles of the other units as it sticks to the former ATX 2.4 specifications, but it will still do the job just fine.

You will have the option of connecting a GPU with up to 4x PCIe 8-Pin connectors. For a GPU with 12V-2x6 connector, you will need to purchase an optional cable.
