Mg43m Motherboard Manual New: Acer
This is the most common information requested for "new" setups (when transferring the motherboard to a new case). The header is usually located on the bottom right of the board.
Typical Pin Configuration (Standard Intel/Acer layout):
Tip: If the power button does not work, try reversing the connector direction on the pins; polarity matters for LEDs (+ and -), but usually not for switches.
The manual says "SATA Mode: IDE." To enable AHCI for an SSD, you must flash to BIOS P01.A4 or later. Without AHCI, a SATA SSD (like a Kingston A400) will work but will not support TRIM, significantly reducing lifespan. acer mg43m motherboard manual new

⚠️ Proprietary Alerts: Front panel header pinouts, fan connectors, and power switch/LED layouts may differ from standard ATX. Using a non-Acer power supply or case may require adapter cables.
If you are reinstalling Windows, you will need the following drivers:
Where to download: Since Acer does not host a dedicated "MG43M" page easily, search the Acer Support Site for your specific Computer Model (e.g., "Aspire TC-120 Support"). The motherboard drivers are listed under the computer model's name.
The MG43M is a micro-ATX or mini-ITX form factor motherboard designed by Acer for AMD processor-based desktop systems. It is primarily found in the Aspire series.
