A Closer Look
Gigabyte’s Z370Xp SLI is considered an ATX form-factor board but doesn’t quite extend to the further column of screws to the right. Other than that, it follows a pretty traditional layout. The board is matte black mostly but has a white pattern splashed across it.
The rear of the board really doesn’t have anything to see, there are almost no components short of some LEDs along the audio line in the board.
Rear I/O covers the bases without any extra fluff. You get dedicated PS/2 keyboard and mouse ports, six USB 3.0 ports, two USB 3.1 ports, HDMI, gigabit ethernet and 8 channel analog audio.
The top half of the board is taken up by the VRM heatsink and rear I/O cover. The CPU socket sits near the middle with a quartet of DDR4 DIMM slots to the right. An M.2 slot sits just under the CPU socket.
The bottom of the board has two PCIe x16 reinforced slots, three PCIe x1 slots and a PCIe x16 regular slot. Another M.2 slot sits between the lower PCIe x16 slots. A thunderbolt expansion header hides between the lowest two PCIe slots.
Along the bottom of the board, you get front panel audio, a Serial UART header, an LPT parallel/printer header, RGB header, TPM Connector, and a pair of USB 2.0 headers. Towards the front, you have a 4-pin fan header that can handle water pumps or high-powered fans, and the front panel I/O connectors.
Going up the front, we have six USB 6.0 SATA ports, another fan header, a pair of front panel USB 3.0 headers and the main 24-pin power connection.
The top edge of the board has 2 fan headers and the CPU’s 8-pin power connection.
