View Full Version : Incidental wiring from case to mobo?

I'm putting a used computer into a new case, and am a little befuddled by the wiring that goes between the case front (power, reset, audio jacks and USBs) and the mobo. The computer is an HP Pavilion 9800 (about 3 years old) that I got for free, and haven't tested, other than just plugging it in and noting that the lights came on, the hard drive spun and the fans worked. (The reason I couldn't test it is because its video/graphics card didn't have a VGA jack taht I could connect to my monitor; just some more exotic jacks. I've replaced that card with a 64mb ATI Radeon card.)

Anyway, the mobo is an Intel Desktop Board D850MV, and the new case is a RaidMax X-1. That case has a hatch in the front that closes over the access to the drives, and the portion of the front panel that contains the USB ports, etc. There is a power/reset switch on the outside of the box. The case has a bunch of little wires snaking into the mobo area, some of which are labeled, such as "power sw" and "reset sw". Others are unlabeled. Two bundles have 4-pin connectors that are labeled for the two USBs, but also have one additional connector attached to each, that's unlabeled.

Before I removed the mobo from the old case, I made a diagram of the wires that went between it and the front panel. All of them fit into a little 2-row matrix of 14 pins, with 8 below and 6 above (there are two pins missing from the upper row). Two of the wires attached to that old case were labeled "LED" and "power", but the other two were unlabeled. I know they weren't for USB ports, as it didn't have those in the front.

Right above that pin matrix are a pair of pins, then a row of 4 and a row of 5 pins. That's about all I can find for pins that look likely to be able to have the wires from the front of the case attached to them. I've searched around the web for a diagram for this mobo, but cannot seem to find one. Can anyone tell me which wires should go where? Any advice would be appreciated.

Here's the link for Intel's D850MV manual (ftp://download.intel.com/support/motherboards/desktop/D850MD/MDMV_English.pdf).
