8 pin power connector, 4 pins on motherboard? Help!

Hello! I am putting together a new build and I am at a stop now because of some trouble. This is my system:

CPU: AMD FX 8120
MOBO: ASUS M5A97 LE R2.0
PSU: Corsair CX500
*I left out components not necessary for my question*

On my motherboard all I see is a 4 pin power input for CPU power. My CX500 doesn't have a 4 pin CPU power plug. The CPU plug on the CX500 has 8 pins. How do I connect this? Should I use my PCI 4 pin power? Is there any way around this?

Thanks for your help!

  1. Hi, I guess that it's a 4+4 pin power supply connector. Try separating them.

    Your 8 PIN CPU connector should SPLIT in half into 2 FOUR pin connectors. Try doing that.

    DO NOT try using a four pin PCI
  3. It might be an 8pin, it should be labeled EPS or CPU power. just plug in the four that fit.


  4. Your 8 PIN CPU connector should SPLIT in half into 2 FOUR pin connectors. Try doing that.

    DO NOT try using a four pin PCI

    Ya.. +3.3V@25A on +5V@20A
  5. I have the exact same supply, the 8 pin splits in half.

    You are my fucking hero! I was so pissed and have been searching to for an adapter for hours with no luck and no forums were helping. I would buy you a beer if i could.
  7. My seasonic 430 bronze cant be split. Should I cut it manually using a blade?
  8. You should be able to split it. Check https://seasonic.com/product/s12ii-430/ the Cables tab
