Packaging and Overview


The box and packaging will do a good job of protecting the motherboard.


The accessory package includes four SATA6Gb/s cables, SLI HB bridge, IO shield, postcard, M.2 screws, driver DVD, manual, and software manual.


ASRock has five fan headers on this motherboard. The CPU fan header is circled in red and supports PWM fans. The other four circled in blue work with either 3-pin DC fans or 4-pin PWM fans. The headers circled in blue also offer up to 2A of current.

The motherboard has some high-end aesthetics with a gray and black color theme. The IO panel cover is a nice touch, as is the merging of the silkscreen on the PCB and design of the heat sinks. The back of the motherboard is bare of most components.


The rear IO panel features PS/2 keyboard/mouse, four USB 3.0 ports, DisplayPort, HDMI, VGA, USB 3.1 type-A, USB 3.1 type-C, Gbit LAN, WIFI antenna bracket, and 7.1 audio outputs with S/PDIF out.


The PCI-E layout is as follows, x16/x0/x4 or x8/x8/x4 as the last PCI-E slot is routed to the PCH. While one of the M.2 slots has a heat sink, both of them run at x4 PCI-E 3.0 and offer SATA support, but they both also share bandwidth with two SATA6Gb/s ports. The M.2 WIFI card slot only supports WIFI cards, but it also supports Intel's new CVNI standard.


Six of the eight SATA6Gb/s ports are wired to the PCH, the other two come from an ASMedia adapter. There are two internal USB 3.0 headers and one internal USB 3.0 type-C header.


At the bottom of the motherboard, we find two USB 2.0 internal headers near a COM port. At the top of the motherboard, we find an 8-pin CPU power connector as well as a 4-pin CPU power connector.


At the bottom we find two RGB LED headers, a Thunderbolt GPIO header, and an addressable RGB LED header. Heatsinks make solid contacts with the components they cool.
