Solved CPU plug 4 / 8 pin and PSU Tags: Power Supplies CPUs Motherboards Last response: January 9, 2014 10:52 AM in CPUs Share joho5 January 9, 2014 5:47:34 AM I just bought a new power supply and it has an 8 pin cpu plug. My motherboard has an 8 pin receptor, but prior, 4 of them were capped off. Im assuming its ok to just take that cap off and plug the 8 pin to the board right? I almost figured this was common sense, but thought id check first. thanks More about : cpu plug pin psu Reply to joho5 Onus a c 122 ) Power supply a c 135 à CPUs a c 142 V Motherboard January 9, 2014 6:04:40 AM Yes, the uncapped pins are used with a 4-pin CPU power cable, and all of them are used with an 8-pin power cable.

With all 8 pins connected there is a potential for better/more stable overclocking........... (more pins / contact area lowers resistance and reduces voltage drop under heavy current draw...)
