Compact LGA 1151 motherboard

The ASUS Q170S1 is a Mini STX board built around the Intel Q170 chipset for LGA 1151 processors. It fits small-form-factor chassis while providing a full desktop feature set. The platform supports DDR4 memory up to 32 GB across two slots. It targets embedded systems, thin clients and space-constrained workstations.

System builders needing a tiny Q170 platform

This board suits integrators assembling compact commercial PCs that require vPro manageability and multiple display outputs. The single PCIe x16 slot allows a low-profile add-in card such as a capture or I/O adapter. Builds needing more than one expansion slot or a standard ATX power connector should consider a larger form factor.

One PCIe 3.0 x16 slot and one M.2 slot

Expansion is limited to a single PCI Express 3.0 x16 slot and one M.2 socket for storage or wireless modules. The rear I/O provides one DisplayPort and one USB 3.1 Gen 2 Type-A port alongside a single RJ-45 Ethernet jack. Verify that your case and power supply match the Mini STX layout before ordering.

Questions about this item

Will this board fit inside a standard Mini STX chassis?

The form factor is Mini STX so it matches any chassis built for that size; verify the mounting hole pattern of your case before ordering.

Which DDR4 modules can I install and how much total memory is supported?

Two SO-DIMM slots accept DDR4 up to 32 GB total; use matching sticks for dual-channel operation.

What expansion cards can I add through the PCIe x16 slot?

The single PCI Express 3.0 x16 slot takes full-height graphics cards or other x16 add-in boards; a legacy PCI slot is also present for older cards.
