Unboxing the ASUS ROG Crosshair VIII Impact

ROG Crosshair VIII Impact is a motherboard released by ASUS under their premium gaming brand Republic of Gamers. As such, its packaging is premium too. It comes in a medium-sized box made of hardened cardboard, and it features the ROG red and black colors with Mayan-inspired lines.

On the back of the box, there are a lot of details about the specifications and features of the motherboard, plus more than a few images of it and its main components. When you open the box, you get to see everything that you've paid for: the motherboard, the user manual, 4 SATA 6Gb/s cables, one DVD with drivers and software, one ROG big sticker, two M.2 screw kits with short screws and mounts, one Wi-Fi antenna, one extension cable for RGB strips with a length of 80 cm, one extension cable for Addressable LED, one panel cable, one ROG coaster, a ROG "Thank you!" card, one ROG SO-DIMM.2 with heatsinks, and one 2-in-1 rubber pad.

Unboxing the ASUS ROG Crosshair VIII Impact is a delight worthy of a premium device. The motherboard looks exquisite from the first encounter, and the bundle of accessories is generous.

Hardware specifications and design

The form factor for ASUS ROG Crosshair VIII Impact is mini-DTX, which is a format that's somewhat unconventional. It is a bit larger than mini-ITX, which is the most common form factor for small computer cases. What does that mean for you as a user? Well, it means that, before you buy this motherboard, you should check whether it fits your small PC case. ASUS ROG Crosshair VIII Impact is 8 inches long and 6.7 inches wide or 20.3 x 17 cm.

A view of the ASUS ROG Crosshair VIII Impact

The motherboard is based on AMD's newest X570 chipset and supports AMD Ryzen processors from the 3rd and 2nd generations, and AMD Ryzen with Radeon Vega Graphics processors from the 2nd and 1st generations. Evidently, the motherboard uses the Socket AM4 specification. If you want to check the full list of officially supported processors, you can do so here: ASUS ROG Crosshair VIII Impact - CPU Support.

The ASUS ROG Crosshair VIII Impact can also accommodate 2 DIMM RAM modules with a total capacity of 64GB and a maximum frequency of 4800 MHz in overclocking mode, together with a 3rd Gen Ryzen CPU. With a 2nd Gen Ryzen CPU, the maximum RAM speed is 3600 MHz.

ASUS ROG Crosshair VIII Impact: There are 2 DIMM slots

Because the Mini-DTX form factor is bigger, it offers more space than mini-ITX. ASUS ROG Crosshair VIII Impact takes advantage of this specification by offering enough space for you to mount a two-slot external PCIe 4.0 x16 graphics card. One small aspect that we couldn't help but notice is the fact that ASUS's designers were inspired and chose to reinforce the GPU slot with a metal frame, to accommodate even the heaviest graphics cards.

Right underneath the graphics card slot, there is also another PCIe 4.0 x4 M.2 slot, but this one is already used by the hardware audio codec built-in on the motherboard. The audio chipset is one of ASUS' top-range choices: a SupremeFX S1220A HD audio codec with ESS ES9023P DAC.

Above the graphics card slot, ASUS chose to do a rather interesting thing: it mounted a dual M.2 riser module, otherwise known as a SO-DIMM.2 slot. If you are wondering what this is, you should know that it's a small card that can fit two PCIe 4.0 x4 M.2 solid-state drives and which you mount in its slot vertically, thus saving quite a lot of space on the motherboard.

Another interesting design choice is how ASUS chose to create the cooling system. On top of the input/output panel, there are two fans that take the heat from the processor's VRMs and from the X570 chipset and blow it out of the case. The cooling system not only looks good, but it is also efficient at its job.

To help with heat dissipation, the motherboard also has a large metal backplate. Besides its utility factor, it comes with a cool design, as you can see in the picture below.

And, as we reached the input-output panel, we should also check the ports and connectivity options available on this motherboard. You can't be anything but satisfied when you get so many options on such a small motherboard: Intel 802.11ax Wi-Fi 6, Bluetooth 5.0, Gigabit Ethernet, six USB 3.2 Gen 2 ports (one of them is Type-C), four SATA 6 Gbps ports, and two M.2 SSD slots that we've already mentioned (on their special vertical mount).

On its IO panel, the motherboard also comes with a BIOS POST code display, a button for clearing CMOS, one for USB BIOS Flashback, and one for reset. Additionally, directly on the motherboard plate, you also get buttons for power, retry POST, and load failsafe BIOS settings.
