The back of the chassis provides the following connections:
The MS-7829 motherboard is a proprietary micro-ATX board manufactured by MSI. It is most commonly found inside pre-built desktop computers, specifically the and Veriton X4630G series. Because it was built as an Original Equipment Manufacturer (OEM) component for Acer, finding an official, standalone retail manual can be difficult.
Because this is an OEM (Original Equipment Manufacturer) board, the front panel headers—responsible for the power button, reset switch, and LEDs—are often unmapped in standard manuals.
(Note: If no jumper cap is present, carefully short the two clear-data pins with a flathead screwdriver for 10 seconds while the system is completely powered down.) Initial Installation and Upgrade Steps ms-7829 motherboard manual
Connects the front headphone and microphone jacks. It complies with the HD Audio standard. Fan Connectors
Located in the upper center. Ensure the triangle marker on your CPU aligns with the pin 1 indicator on the socket corner.

Look at the sticker on the back of your computer. If it says "Pro 24X 8M-040US" or similar, go to the MSI Support page and type that full model number. The manual for that system contains the motherboard layout. | Label | Function | Default Setting |
Understanding the technical boundaries of the MS-7829 ensures component compatibility and prevents hardware damage during upgrades.
Connecting the case cables to the motherboard front panel header (usually labeled ) is the most common challenge during assembly. Use the layout below to wire your power button, reset button, and status LEDs. The header typically features 9 pins arranged in two rows:
Since MSI does not publicly list the MS-7829 on its main consumer site (it’s an OEM/system-integrated model), try these sources:
The MS-7829 is built on the Intel H81 or Q85 chipset (depending on the specific Lenovo revision). It supports 4th-generation Intel processors and uses a compact Micro-ATX form factor. Specification Intel LGA 1150 Supported CPUs | | JUSB1/JUSB2 | USB 2
Plug the power cable back in and power on the system. The BIOS will revert to factory default settings. Common Beep Codes:
Plug the power cord back in, power on the system, and enter the BIOS to reconfigure your settings.
Tech Tip: If you are migrating this board into a standard aftermarket PC case, you will need to manually map your individual case wires to these specific pins, as standard cases use a split header configuration. 4. Audio and USB Headers Front Panel Audio (JAUD1)
It typically features four DDR3 DIMM slots, supporting up to 32GB of dual-channel memory.
