Motherboard Layout

The ECS Z87H3-A3X motherboard features a dark brown colored PCB with gold accents on the capacitors and heat sinks. Because of the board's stripped down feature-set, there is more then sufficient space around all integrated components. ECS does include enhanced heat sinks to maximize the heat sink transfer capabilities without using existing in-case airflow.

The back of the board contains nothing but trace-lines and solder points, minimizing passive from case or CPU cooler install.

ECS designed the Z87H3-A3X with the following ports integrated into its rear panel: a PS/2 keyboard and mouse port, four USB 2.0 ports, four USB 3.0 ports, one eSATA 6 Gb/s port, an Intel GigE NIC port, a VGA video port, a DVI-D video port, an HDMI video port, an optical S/PDIF audio output port, and 5 analogue audio ports.

The Z87H3-A3X motherboard has a total of six device ports – two PCI-Express x16 slots and four PCI-Express x1 slots. For the PCI-Express x16 slots, the board supports full x16 bandwidth with a single card and x8 bandwidth with cards in the primary and secondary slots. Notice that ECS designed the boards PCI-Express slot layout so with a PCI-Express x1 slot to the right of the primary z16 slot so that an x1 slot remain available. Further, the x16 slots support video cards with up to tri-slot coolers without impeded board function or case fitting.

In the upper left corner of the board are the S/PDIF input header, the front panel audio header, the parallel port header, and the serial port header.

Along the lower left of the second PCI-Express x16 slot are the trusted platform module header, the chassis intrussion header, the speaker and front panel headers, the USB 2.0 headers, a system fan header, the CMOS battery, and CMOS reset jumper. If using multiple video cards in the system, you may have a hard time accessing the CMOS battery and/or CMOS reset jumper. The grey colored USB 2.0 header, labeled F_USB1, can be used in conjunction with the EZ Charge technology to fast charge an attached device. Ports attached to this header are rated to provide 3x the normal current output.

The six on board SATA 6 Gb/s ports are located in the lower left corner of the board. The SATA ports are placed so that the cables will sit perpendicular to the plane of the board which could be problematic when using a full length video card with a large cooler in the secondary PCI-Express x16 slot. Note that the grey colored port is disabled when a device is plugged into the eSATA port in the board's rear panel.

The Intel Z87 Express chipset's cooler is a large, low profile aluminum heat sink just in between the PCI-Express x16 slots and the bottom edge of the board. The heat sink is gold colored with the ECS L337 Gaming logo prominently displayed. The heat sink is finned with is fins situated at an angle to increase the surface area for heat dissipation. To the lower right of the chipset is the USB 3.0 header.

The on-board DDR3 memory slots are located just below the CPU socket in the lower right quadrant of the board. Dual Channel memory mode is enabled by seating memory modules in slots 1 and 3 or slots 2 and 4 with slots 2 and 4 being the primary memory slots. The board supports up to 32GB of memory running at a maximum speed of 3000MHz. Note that memory speeds above 1600MHz are considered overclocked speeds and are outside of the official Intel stock memory speed specifications. In between the memory slots and the board edge are the Intel Z87 chipset controlled USB 3.0 header, the 24-pin ATX power connector, and a system fan header.

To the upper right of the DIMM slots are two fan headers that can be used for the CPU cooler fans or a header powered water pump.

The CPU socket is clear of obstructions with the power circuitry and VRM heat sink located above the socket. While the power chokes and upper capacitors look to be close in proximity to the socket, there was no issues encountered mounting any of the test coolers to the board. The included VRM heat sink is a large and solid chunk of aluminum with air channels cut int to it to increase surface area. The heat sink itself appears to spell the work L337 if looked from straight on.

To the upper left of the CPU socket and to the left of the CPU VRM heat sink is a system fan header.

The on-board 8-pin ATX12V power connector is located to the upper right of the CPU socket and to the right of the power chokes and VRM heat sink.
