Do i need to use both cpu power connector. Usually the 8 pin is only needed.

• Do i need to use both cpu power connector. So 8 pin + an addition 4 pin. I was looking to upgrade my computer and looking at some motherboards and saw that some motherboards have two 8 pin connectors for the cpu however my power supply only Hi, I am planning to buy MSI Z690 Tomahawk DDR4 motherboard with 12700K CPU. The problem im having currently is that my old PSU For the CPU to get powered, only one 8-pin EPS connector plugged into CPU_PWR1 is necessary. You don't even need it for the 7950X. The question is in the title. A reviewer I saw yesterday was measuring the CPU EPS 12V rails connector for CPU power draw before VRM losses. One eps 8 pin is more than enough and provides 300w+ while a 7800x3d only needs 65-80w while gaming. Put simply, electricity The motherboard I purchased has two 8-pin CPU power connectors, but my power supply unit only came with one 8-pin CPU power cable. The second connector is there to spread the total power distribution over two plugs and two cables, in So, at least for Ryzen 3000, I think you need to connect both CPU connectors to avoid Windows 10 freeze. The power supply comes with 2x (4+4 pins). Maybe an issue if you plan to heavily overclock and unlock power limits and such. The second header CPU_PWR2 is there to spread the total power You actually don’t need both connectors. I see the motherboard has (2) 8 pin CPU power inputs. The I upgraded to MSI Z690-A mobo and i9-12900K. Unless you're using a very low quality psu you should have at least two 4 pin cpu power cables that can be connected to make one 8 pin connector.
