Acer Ironman-sk Motherboard Specs -

When diving into the world of pre-built desktop PCs, especially those from mass-market giants like Acer, enthusiasts often encounter a frustrating reality: proprietary hardware. The Acer Ironman-SK is a perfect example. You won't find this motherboard on Newegg or Amazon. It’s an OEM (Original Equipment Manufacturer) board, typically found inside Acer’s Aspire TC, Aspire T3, and some Predator gaming desktop lines.

If you own a PC with an Ironman-SK board—or are considering buying a used Acer desktop—understanding its specifications is critical for upgrades, troubleshooting, or building a hackintosh. Below, we break down every spec, from chipset details to hidden jumpers.

The Ironman-SK is a decent H170 board for its time but is not recommended for a new build due to proprietary power, form factor, and limited BIOS. It is best kept with its original Acer power supply and case.

What you can do:

If you are the proud owner of an Acer Predator G3-605 desktop (or you found one at a thrift store for a steal), you’ve likely come across a mysterious motherboard label: Ironman-SK.

Unlike retail motherboards from ASUS or MSI, this board is an OEM (Original Equipment Manufacturer) part designed exclusively for Acer. You won’t find “Ironman-SK” printed on a box at Best Buy, but understanding its specs is crucial if you plan to upgrade your CPU, RAM, or troubleshoot drivers.

Here is everything you need to know about the Acer Ironman-SK.

Here is the authoritative spec sheet for the Acer Ironman-SK (most common variant).

Only if: You find a used Predator G3-710 for cheap ($100–150) with a dead GPU but good CPU/RAM. Pull the board, add a new power supply (using a 24-pin adapter), and you've got a sleeper. Acer locks down the Ironman-SK BIOS severely

Avoid if: You want to overclock, need modern I/O (USB-C/3.2), or hate tinkering with non-standard parts.

The "Ironman" codename is Acer's internal designation for a series of micro-ATX motherboards based on Intel’s 100-series and 200-series chipsets. The "-SK" suffix often denotes a specific revision tailored for Acer's chassis and power delivery.

Key Identifier: Look for the board itself. It typically has a matte black or dark brown PCB, four SATA ports, a single PCIe x16 slot, and a proprietary 12-pin power connector (instead of the standard 24-pin).

Common System Matches:

The M.2 slot supports only PCIe x2 (not x4), so high-end NVMe drives get bottlenecked to ~1,500 MB/s. However, it also supports SATA M.2 drives in the same slot—something even some retail boards don't do well. A cheap 512GB SATA M.2 is the perfect speed bump for this board.
