Are you referring to the 8-pin CPU power connector? You need that plugged in to start the computer.

Does the connector from the PSU look like this? 8-pin CPU connector

The 4-pin connector could be the PCI power cable but can you tell us what the PSU is?

PCIe power connectors are either 6-pin for 75W or 6+2 for 150W.

If your computer runs on 4 out of the 8 pins then just leave it alone and have a working computer. I remember that I had this weird problem too but after waiting a few months the motherboard decided that I could then plug in the rest of the 8-pin connector.

When you use 4 pins does your computer work fine or are there problems?

Are you 100% certain you are using the 8-pin EPS12V connector? It looks very similar to a 8-pin PCIe power connector but on the PCIe power connector, 12V and GND pins are on opposite side from EPS12V. If you used the wrong connector, the 12V lines are being shorted to ground on the motherboard.

Your computer works with the 4-pin ATX12V cable. I would simply plug that in and call it a day.
