I have an MSI P965 Platinum.

It has the standard 24-pin power and 8-pin power plugs like I'd expect. But just below the 8-pin is a 4-pin molex plug too. (The kind used for CR-ROM, HD, peripherals.)

MSI's manual is less than helpful is describing what this is used for.

Any idea why the mobo needs 3 power connectors?
 
Just built one for a friend with the same mobo. The manual mentions it is for supplying power to stable the operation of the video card. I put a 7950 GT in his system, so i hooked up the connection just in case. I've seen a few boards that have that (on the AMD side, the Asus A8N SLI Deluxe for example). I'd say hook it up just to be safe.
 
thanks for the info, when my roommate built his machine with an MSI P4N Diamond in October of last year, we saw a molex connector on the mobo called "JPOWER" but the manual never explained it....we figured it may have been for SLI since at the time he only had a single 7800GTX in there.
