I recently purchased an ECS GF6100-M754 motherboard and as I was in the process of installing it I noticed that there was an additional 4-pin power connector next to the 754 cpu socket. Most of my technical experience is with much older mb's and cpu's so this is the first time I've encountered that connector. I've read through the mb manual which doesn't give any description as to what the connector is used for. The only thing the manual says about the connector is this:

Connect the auxiliary case power supply connector to PWR2

The link below contains an image of the motherboard. The 4-pin connector can be seen at the bottom left corner of the cpu socket.


What is the connector for? Do I need to connect my power supply to it for the cpu to receive power? And what is a auxiliary case power supply?

The 4 pin connector (also known as the 12v connector) is required to provider power to the CPU. It is compulsory to plug it in, otherwise the board will not POST. All boards with this connector or later revisions of a similar connector require it to be connected in order to do anything. Early revisions provided it, but didn't need it connected.

Auxiliary power supply is your power supply, the big grey box that you plug the mains into :) Otherwise known as external input aka electricity :) Unfortunately computers don't run on fresh air (yet).
