[SOLVED] Do I need to use 4 pin with 8 pin motherboard power connector?

[Arthur Morgan]

Hello guys! Noob here with noob qestion ;-)

I want to connect my motherboard (Asus ROG STRIX B660-G GAMING WIFI) to fully modular Seasonic GX-750. On motherboard there is in top left one ATX_12V_2 four pin power connector, next to it there is another eight pin ATX_12V_1 power connector. I have connected RE25 8 pin to CPU/PCI-E and to that 8 pin ATX_12V_1. Please tell me do I need to use also that 4 pin ATX_12V_2 ? I use i5-13600KF with RTX 3080Ti OC from Zotac.

Please help me

the motherboard has an 8-pin and 4-pin cpu power connection.

your psu only has an 8-pin cpu connection. so plug in the 8-pin and that's all you can do. pcie connections are not for that and can not be used so don't try.

the labels on the psu are only telling you that you can plug the 8-pin cpu connection into any of those 4 slots, not that you have multiple cpu connectors.

Thank you @Math Geek , tell me please, those additional 4 pins are for overclocking purpose?

yah they are for extra cpu power, not just for overclocking but for the more power hungry higher end cpu's.

from what i have seen the 13600 is not as bad and should be ok with the single connection.

however, i would pay attention to the system first week or so and be sure it is not being power starved. it might be that the 4 pin is needed, but i am not sure since without digging further. but i doubt it for that cpu.

Thanks a lot for clarifying, you're great person.
