Which GPU do you have? They use more power than CPU so PSU power rating is usually tailored for them. Normally you don't need more MB power than basic one unless overclocking and/or using a lot of PCIe lanes.Hi, Is Corsair HX750 enough for Ryzen 9 7950X? That PSU has only 8pin connector for CPU supply, no additional 4pin, on my board GIGABYTE X870 EAGLE WIFI7 there is 8+4 for CPU.
