Packaging and Overview
The motherboard's box uses the same design and color theme as the rest of ASRock's Fatal1ty lineup. Packaging is the same as well; the motherboard sits in a foam bed inside an anti-static bag.
The accessory package includes an IO shield, two SATA6Gb/s cables, M.2 screws, ASRock case badge, driver DVD, postcard, and manuals.
The motherboard only offers three fan headers, which makes sense given the affordable price of the motherboard. All three headers can work in either DC or PWM mode; you can change the mode in the UEFI.
The motherboard offers a red and black color theme and has some hints of red on its PCB silkscreen. I am surprised that at this price point ASRock decided to offer enthusiast aesthetics and to be perfectly honest, I like the physical design of their VRM heat sinks. The VRMs on these motherboards get warm, and I am glad ASRock decided to cool all of them. The back of the motherboard is super clean and smooth.
The rear IO panel features two USB 2.0 ports, PS/2 keyboard/mouse, VGA, DVI, HDMI, USB 3.1 type-A, USB 3.1 type-C, four USB 3.0 ports, a Gbit NIC, and three audio outputs (microphone, headphone, line-in).
The PCI-E layout is simple; the reinforced slot is x16 PCI-E 3.0 wired to the CPU. The second x16 slot is electrically x4 PCI-E 2.0 and shares its bandwidth with the second M.2 slot. There are also four PCI-E x1 PCI-E 2.0 slots. Two RGB LED headers are located in the upper right-hand corner of the motherboard.
There are two M.2 slots; the top one is wired 32Gb/s to the CPU while the bottom one is wired 20Gb/s to the chipset and shares bandwidth with the second x16 slot.
Under the 24-pin connector are a USB 3.0 internal header and two straight angled SATA6Gb/s ports (wired to an ASMedia controller). Four other SATA6Gb/s ports are angled 90-degrees and wired to the chipset.
There are two internal USB 2.0 headers located to the left of the clear CMOS header. The motherboard has heat sinks over all the VRMs and on the chipset. The VRM heat sinks use pushpins rather than screws, but the PCH heat sink uses screws.
