Packaging and Overview
The white and black box uses the same color theme as the motherboard. Packaging is well done and will protect your motherboard just fine.
The accessory package includes IO shield, two SATA6Gb/s cables, M.2 screws, case badge, driver DVD, and manual.
We find four fan headers on the motherboard, all of them are 4-pin PWM/DC mode headers, and we believe they support up to 1A of current. Fan control is done through the UEFI or through ASRock's Windows application. The motherboard features a mostly black PCB and color theme, but with silver heat sinks and a large white portion in the middle. The back of the motherboard is bare of most components.
The rear IO panel features two USB 2.0 ports, PS/2 keyboard/mouse, DVI, VGA (D-SUB), HDMI, five USB 3.0 ports, one USB 3.0 type-C port, 1Gbit LAN, headphone out, line in, and microphone ports.
The first x16 slot is wired x16 and the second x16 slot is wired x4. Both of these x16 slots are PCI-E 3.0 slots and do not share bandwidth with each other. The second x4 PCI-E slot gets its bandwidth from the CPU because it shares all its bandwidth with the M.2 M2_1 slot. All four PCI-E x1 slots are x1 PCI-E 2.0 from the PCH.
The second M.2 slot is a SATA M.2 slot, so PCI-E based M.2 drives won't work. SATA6Gb/s ports at a 90degree angle are from the FCH (chipset).
Two more SATA6Gb/s ports get their bandwidth from an ASMedia controller. We also get a USB 3.0 internal header on the motherboard. Two RGB LED headers are located at the top of the motherboard.
The motherboard also features an HD audio header, TPM header, and COM header. We also fine two USB 2.0 internal headers, a clear CMOS jumper, and front panel headers in the lower right corner of the motherboard.
Heatsinks make solid contact with the motherboard and the components they cool.
