ASUS PRIME Z270-K LGA 1151 ATX Motherboard

The ASUS PRIME Z270-K is an ATX motherboard built for Intel LGA 1151 processors from the 6th and 7th generation Core i7, i5, i3, Pentium and Celeron families. It supports DDR4 memory up to 64 GB across four DIMM slots with overclocked speeds reaching 3866 MHz. The board provides integrated graphics outputs via HDMI 1.4b, DVI-D and VGA, plus dual M.2 sockets for SATA or PCIe storage.

Suits 6th-7th Gen Intel builds; avoid for newer CPUs

This motherboard suits builders assembling or repairing systems based on 6th or 7th generation Intel Core processors who need DDR4 memory and M.2 storage options. It is not compatible with 8th generation or later Intel CPUs, so anyone planning a current-platform build should select a board with a newer socket and chipset.

LGA 1151 socket decides CPU compatibility

The single specification that determines whether this board fits your build is the LGA 1151 socket, which only accepts 6th and 7th generation Intel Core, Pentium and Celeron processors. Verify your CPU generation before purchase; a mismatched processor will not install or function on this platform.

Questions about this item

What does the 64GB DDR4 limit mean when I fill all four slots?

You can install up to 64GB total across the four DIMM slots using DDR4 modules. The board runs dual-channel mode and supports overclocked speeds up to 3866 MHz depending on the CPU and memory kit.

How fast is the M.2 socket that takes 22110-length drives?

The first M.2 socket supports both SATA and PCIe 3.0 x4 modes for drives up to 22110 length. The second M.2 socket supports SATA and PCIe 3.0 x4 for drives up to 2280 length.

What clearance does the reinforced PCIe x16 slot need for a heavy graphics card?

The primary PCIe 3.0 x16 slot uses a fortified SafeSlot Core design. It follows standard ATX mounting holes, so any case that accepts ATX boards will fit. The board itself measures standard ATX dimensions.
