If you need specific drivers for the onboard Realtek audio or Intel networking, visit the Acer Support Page and enter your system's Serial Number

. Because this is an OEM board, drivers are usually listed under the model of the desktop it came in (e.g., Predator G3620). front panel header pinout to help with moving this board into a new case? Download Acer Support Drivers and Manuals

This is the "gotcha" with the IPIMB-AR. While the board features a standard 24-pin ATX Power connector and a 4-pin CPU power connector, Acer power supplies are sometimes built to slightly non-standard efficiency curves.

However, the good news is that the IPIMB-AR Rev 1.02A generally works perfectly fine with standard ATX power supplies from brands like Corsair or EVGA. It does not require proprietary voltage rails like some older Dell boards. If you are transplanting this board into a standard case, a generic 500W PSU will run it without issues.

The IPIMB-AR is an Intel-based motherboard utilizing the LGA 1156 socket. This places it squarely in the era of the first-generation Core i3, i5, and i7 processors (Lynnfield and Clarkdale architectures).
