Socket LGA 1150 Z87 ATX Motherboard

This ASUS Z87-K board fits the Intel LGA 1150 socket and supports 4th-Generation Core i7, Core i5, Core i3, Pentium and Celeron processors. The Intel Z87 chipset provides native SATA 6Gb/s and USB 3.0 connectivity on a standard ATX layout.

System builders using 4th-Generation Intel CPUs

The four DDR3 slots accept dual-channel kits up to 32 GB with overclocked speeds reaching 2933 MT/s. Builders needing newer CPU sockets, different memory types or integrated wireless should look at alternative platforms.

One PCI Express 3.0 x16 slot

A single full-length PCI Express 3.0 x16 slot handles the primary graphics card while a second x16 slot runs at x4 and two x1 slots plus three legacy PCI slots provide extra expansion.

Questions about this item

Will the four DDR3 slots hit the 32GB ceiling before the CPU throttles under sustained load?

The board supports up to 32GB of DDR3 across four slots; sustained CPU throttling depends on the processor and cooler you install, not the motherboard itself.

How loud and hot does the VRM area get when the system runs all day with Fan Xpert 2 active?

Fan Xpert 2 lets you tune chassis and CPU fan curves for a quiet, cool balance; actual VRM temperature and noise vary with your CPU, case airflow and chosen fan profile.

Which 4th-generation LGA 1150 processor do I need to have already for this board to POST?

Any 4th-generation Core i7, i5, i3, Pentium or Celeron in the LGA 1150 package will work; the board also requires DDR3 memory, a PSU with 24-pin and 8-pin CPU power, and a graphics source if the CPU lacks integrated graphics.
