What is 6 pin on motherboard for?

Discovered this on an old X99 board I just purchased. Above the top DDR3 socket is a six-pin connector, matching what you'd see on a graphics card. What might it be used for? Thanks!

Yes, exactly like this.

It's typically used to provide extra power for multiple GPU setups on PCIe power delivery.

This looks like it's compatible with an ATI XFire board. Appreciate the confirmation!

To add extra power to the PCI-E ports, as @Skiiwee29 noted, we need a more consistent supply. The specifications allow up to 75W per port, which should help stabilize the connection.

Usually this provides additional performance when connecting several GPUs together, like in an SLI configuration. Earlier boards also used this method, generally with a four-pin connector. I've included a picture of an EVGA nForce 680i SLI board that uses the same four-pin setup for extra power. It's only needed for special cases.

The Molex power likely handles the same functions for SATA and IDE as well. Fascinating setup, thanks!

The Molex connector in the 680i SLI serves as an alternative method for supplying power to the PCIe GPU slots, especially useful when connecting several GPUs. On my system, I didn’t need it since I was only using one GPU.

Only two 12V cables are available on the ATX 24-pin connector, which could cause overheating and damage if you add more than two high-performance graphics cards.
