The motherboard is an OEM (Original Equipment Manufacturer) board produced by MSI specifically for Acer. It is most commonly found in the Acer Aspire TC-605 , TC-705, and XC-605 series desktop computers.
The board is built on the and uses the LGA 1150 (Socket H3) architecture. This means it primarily supports 4th Generation Intel Core (Haswell) processors. Compatible CPUs
The first major limitation is the BIOS (Basic Input/Output System). Unlike retail motherboards from ASUS or Gigabyte, which receive regular microcode updates for a wide range of CPUs, the MS-7869 is locked to a vendor-specific BIOS. Manufacturers often disable support for certain processors—even those physically compatible with the socket (LGA 1150)—to differentiate product tiers. For instance, while the chipset may support Xeon E3-1200 v3 series CPUs, the BIOS on the MS-7869 almost universally blocks them. This software-level gatekeeping ensures that a budget office PC cannot be easily transformed into a workstation.
