I May Have Slightly Overlooked Something

Hi all

I bought a Gigabyte 787X-OC to go with my new I5. However I just noticed that the motherboard requires a 4 pin and a 8 Pin ATX 12v but my PSU, an generation old Corsair HX 650 Bronze only has one 8 pin connector. Does anyone have any suggestions other than buy a new PSU?

Plug the 4pin cable into the 4pin socket

It doesn't need both.

Are you sure? I'm talking about the two at the top not the PCIE extra power in middle.

Thanks, I was panicking a bit there.

According to the manual, you should have an 8 pin.

• EPS12V CPU cable: 1 x 600mm (23.6”) 8-pin.
Note: The EPS12V power connector has a detachable 4-pin mechanism in order to
support either an 8-pin socket or a 4-pin “P4/12V” socket on the motherboard.

I use the 8pin ATX connector, you don't need both that's for sure.

That what I meant sorry, there is an 8 pin and a 4pin sockets, my PSU only has a 8.

Just plug the 8 pin cable into the 8 pin socket.

I was going to do that, I was thought that it would not boot if I left the 4 pin empty.

Why would a mobo have two power connectors if it'll work OK with only one of them connected?

Usually the 2nd is only required for extreme CPUs and/or when your really pushing overclocking i.e. in the LGA775 days you only needed 2x4 pin in most cases if you were using a power hungry quad core instead of a dual core.
