Packaging and Overview
The box has the same design as the other Z390 Phantom Gaming motherboards, and the packaging is well done.
The accessory package includes four SATA6Gb/s cables, SLI HB bridge, M.2 screws, Post Card, Driver DVD, manual, and a case badge.
There are five fan headers on this motherboard. The one circled in red is a 1A PWM header for the CPU cooler fan. The other four headers circled in blue are capable of up to 2A of current and can operate as DC or PWM mode fans. The motherboards color theme includes both the silkscreen on the PCB and the colors on the heat sinks. The rear of the motherboard has some chips, but it's pretty barren otherwise.
The rear IO panel features PS/2 Keyboard and Mouse, four USB 3.0 (5Gb/s) ports, a USB 3.1 (10Gb/s, labeled USB 3.2) type-A port, a USB 3.1 (10Gb/s, labeled USB 3.2) type-C port, DisplayPort, HDMI, 2.5G LAN, two 1G LAN, and gold plated 7.1 audio outputs with S/PDIF.
The PCI-E layout is as follows, x16/x0/x4 or x8/x8/x4. Both M.2 slots operate at x4 PCI-E, and it looks as if they share bandwidth with some of the SATA ports. Both M.2 slots have heat sinks, but the heat sink on the top one can be a bit tough to get off since it has a thermal pad that kind of glues it to the PCH heat sink. It's possible to separate it from the PCH heat sink, but it requires some pressure. There is also a WIFI M.2 card slot.
There are eight SATA6Gb/s ports, two of which come from an ASMedia controller while the rest are from the PCH. There are two USB 3.0 internal headers and a USB 3.0 type-C header.
At the top right of the motherboard, we find a power button and a reset button. In the bottom right corner of the motherboard, we find our front panel headers, a TPM header, and two USB 2.0 internal headers.
We also find an addressable RGB LED header near two RGB LED headers, a Thunderbolt GPIO header, and our HD audio header. The motherboard offers one 8-pin power header and one optional 4-pin power header for CPU power.
The motherboard's heat sinks are all screwed into the motherboard. The motherboard is also the first ASRock motherboard with an integrated IO shield.
