Before diving into the manual details, it is critical to understand what this board is. The Acer H81H3-AM V10 (sometimes printed as H81H3-AM v1.0) is a micro-ATX motherboard manufactured by Acer Inc., leveraging the Intel H81 chipset. It was designed exclusively for Acer’s mid-range desktop lineup between 2013 and 2015.
This is the most requested section. Below is the data extracted from the official Acer service schematics.
This is not a retail motherboard you would buy in a store. It is a proprietary OEM motherboard made for Acer Predator and Acer Aspire desktop PCs (e.g., Predator G3-605, Aspire T3-715, ATC-705).
You bought an i7-4790K or Xeon E3-1231 v3, but the screen stays black. Solution: The V10 motherboard requires BIOS version P11 or newer for Haswell Refresh CPUs. You must reinstall your old Celeron/Pentium, update the BIOS using the Acer Windows tool, then swap the new CPU.
While a dedicated "H81H3-AM V10" manual is rare, you can find the Acer Aspire TC-603 Service Guide. This document contains the motherboard pinouts, CMOS clear procedure, and BIOS recovery steps.
If you cannot find it, many third-party manual repositories (like ManualsLib or ManualsOnline) host the TC-603 service guide.
Searching for the official "Acer H81H3-AM V10 manual" can feel like a digital scavenger hunt. You are not alone. Thousands of users who own Acer desktops like the Aspire TC-603, Veriton X2630G, or Aspire XC-605 often find themselves on this exact quest. Acer, like many OEMs (Original Equipment Manufacturers), does not always publish a standalone, glossy manual for its proprietary motherboards. Instead, the documentation is often embedded within the full system guide or scattered across support forums.
If you have landed here, you likely need to know how to install RAM, configure BIOS settings for a new SSD, connect the front panel headers, or troubleshoot a boot failure.
This article serves as the complete, crowd-sourced manual for the Acer H81H3-AM V10 motherboard. We have compiled the pinouts, specifications, BIOS recovery steps, and jumper settings that you would typically find in the official PDF.
