Based on verified specs and successful community builds, here is everything you need to know about compatible processors for the Go to product viewer dialog for this item. The Foundation: Chipset and Socket MS-7869 Ver 1.0
Engineering samples (ES) or Xeon CPUs – they are not verified for this board.
While the LGA 1150 socket physically fits many processors, the MS-7869 motherboard has strict limitations. 1. No Overclocking ("K" Series CPUs)

Intel Pentium/Celeron: G3220, G3258, G1820. Acer Community Technical Specifications Specification LGA 1150 (Socket H3) Intel H81 (Lynx Point) Form Factor Micro-ATX (Proprietary to Acer cases) DDR3 SDRAM (Up to 16GB, 2 slots) 1x PCIe x16, 1x PCIe x1 Important Compatibility Notes BIOS Requirements:
When verifying CPU support on the H81 platform, you must account for chipset bottlenecks that affect CPU performance.
For most users, the represents the best overall upgrade . It offers the highest clock speeds and Hyper-Threading support for the best possible performance. If you are on a tighter budget, the Intel Core i5-4690 provides an excellent balance of price and performance for gaming and everyday use. Based on verified specs and successful community builds,
While some Intel Xeon E3-1200 v3 processors (like the Xeon E3-1241 v3) may physically fit and boot, they are not officially supported
For the best compatibility with (those starting with "4?90", like the i7-4790), you may need a BIOS update. As this Acer Community discussion notes, the TC-605 board has had several updates to improve stability. Always perform a BIOS update before replacing the CPU, and do so with extreme caution. 2. TDP Limits and Cooling
The MS-7869 Ver 1.0 requires a specific BIOS version to recognize "Haswell Refresh" CPUs (such as the i7-4790 or i5-4690). If your BIOS is outdated, installing a newer CPU will result in a black screen with fans spinning at maximum speed. How to Prepare: Keep your old CPU installed to update the BIOS. Go to the official Acer Support website. Search for your desktop model (e.g., ). If you share with third parties, their policies apply
, alongside structural, electrical, and BIOS requirements to ensure a seamless upgrade. Motherboard Overview & Core Specs
: Generally supports CPUs up to 84W (like the i7-4770), though 65W "S" variants are common in small form factor builds Upgrade Recommendations
