MSI Z170-A PRO Motherboard

The MSI Z170-A PRO is an ATX motherboard built on the Intel Z170 chipset for LGA 1151 processors. It supports 6th generation Intel Core i3, i5 and i7 CPUs as well as Pentium and Celeron models. Dual-channel DDR4 memory runs up to 3200 MHz when overclocked with a maximum capacity of 64 GB.

Expansion Slots and Connectivity

The board provides two PCIe 3.0 x16 slots operating in x16 or x16/x4 modes, three PCIe 3.0 x1 slots and two legacy PCI slots. Storage options include one M.2 interface, one SATA Express interface and six SATA III ports. Rear I/O supplies two USB 3.1 Gen2 ports at 10 Gbps and four USB 3.1 Gen1 ports, with two additional Gen1 headers onboard. Gigabit LAN and 7.1-channel audio complete the feature set.

Target Builder and Limitations

This motherboard suits builders assembling a 6th generation Intel system who need multiple expansion slots and high-speed USB on a standard ATX form factor. It is not for buyers who require a newer socket or chipset, those who need integrated Wi-Fi or Bluetooth, or anyone looking for a smaller micro-ATX board. The refurbished unit ships with an I/O shield and one SATA cable only.

Questions about this item

Will the CMOS battery on the MSI Z170-A PRO need replacing later?

The board ships with a metal battery installed; it powers the real-time clock and BIOS settings and will need replacement when the system loses time or settings after power-off.

What limits sustained performance on the MSI Z170-A PRO?

The Intel Z170 chipset and VRM design set the thermal and power ceiling; prolonged heavy loads will hit those limits before the PCIe 3.0 x16 slots or memory bandwidth saturate.

How much fan noise and heat should I expect from the MSI Z170-A PRO running all day?

The Realtek ALC887 audio, RTL8111H LAN and ASMedia ASM1142 USB controllers run cool; total board power stays modest so case airflow normally keeps temperatures and noise low.
