LGA 1151 Z270 ATX board

The ASUS PRIME Z270-A is an ATX motherboard built around the Intel Z270 chipset for 6th and 7th generation Core i7, i5, i3, Pentium and Celeron processors in the LGA 1151 socket. It provides four DDR4 memory slots supporting up to 64 GB in dual-channel mode with overclocked speeds listed up to 3866 MT/s. Onboard video outputs include DisplayPort 1.2, HDMI 1.4b and DVI-D for integrated graphics use.

Ideal for 6th and 7th Gen Intel builders

This board suits builders assembling a new system with a 6th or 7th generation Intel Core processor who need multiple expansion slots and dual M.2 sockets. It is not compatible with Intel 8th generation CPUs, so anyone planning to use an 8th generation chip should select a 300-series chipset motherboard instead.

Two full PCIe 3.0 x16 slots

The deciding specification is the PCI Express layout: two slots wired for PCIe 3.0 x16 that can run at x16 or dual x8, plus a third x16 slot limited to x4 mode. This arrangement determines whether the board can support a dual-graphics configuration at full bandwidth or only at reduced speeds.

Questions about this item

What case and power connectors does the ATX board require to fit and mount?

The board uses the standard ATX form factor with a 24-pin main power connector and an 8-pin CPU power connector, and it mounts via nine ATX screw holes in any compatible chassis.

How do I install DDR4 memory in the four 288-pin slots, and what step do builders often miss?

Align the notch on each module with the slot key, press down firmly until both side clips click, and then enable the XMP or DOCP profile in BIOS so the memory runs at its rated speed instead of the default 2133 MT/s.

Which M.2 SSD lengths does the board accept, and when will a drive need replacement?

The M.2_1 socket supports 2242, 2260, 2280 and 22110 lengths in both SATA and PCIe modes, while M.2_2 supports 2242, 2260 and 2280 in PCIe mode only; replace a drive when its health monitoring tools report worn-out NAND or when you need more capacity.
