ASUS déploie l'impact du ROG Crosshair VIII - pas strictement Mini-ITX



ASUS over the past week rolled out its flagship socket AM4 motherboard for SFF gaming PC builds, the ROG Crosshair VIII Impact. Based on the AMD X570 chipset and supporting the latest 3rd generation Ryzen processors, this board is slightly longer than the Mini-ITX specification, while retaining its mount-hole layout. The logic here is that most ITX gaming PC cases have two expansion slots to accommodate dual-slot graphics cards, and so it would make sense to extend the motherboard's PCB up until there, reclaiming precious PCB real-estate. Technically this board would qualify as mini-DTX, but ASUS believes it should fit in most ITX cases that have two expansion slots. The board's dimensions are 203 mm x 170 mm.

Le ROG Crosshair VIII Impact tire son énergie d'une combinaison de connecteurs ATX 24 broches et EPS 8 broches, conditionnant l'alimentation du SoC AM4 à l'aide d'un VRM massif à 8 phases. Le socket AM4 est câblé à une paire d'emplacements DDR4 DIMM, au seul emplacement d'extension de la carte, à un PCI-Express 4.0 x16 et à l'emplacement SO-DIMM.2, qui porte un nom intéressant. Physiquement, il s'agit d'un emplacement SO-DIMM qui a été recâblé avec PCIe gen 4.0 menant à une carte fille SO-DIMM propriétaire qui contient deux emplacements M.2-2280 avec un câblage PCIe 4.0 x4 et SATA 6 Gbps, chacun. Quatre ports SATA 6 Gbit / s constituent le reste de la connectivité de stockage. La zone de la carte mère juste en dessous du slot PCIe x16 a un autre slot propriétaire qui contient la deuxième carte fille, celle-ci avec la solution audio intégrée SupremeFX Impact IV, qui a été physiquement isolée du PCB principal, et possède un Realtek ALC1220 blindé EMI. CODEC principal, DAC ESS Sabre ES9023P pour le canal stéréo principal, un circuit de décompression et des condensateurs de qualité audio. The chipset and VRM are cooled by an elaborate compound heatsink arrangement similar to the one on the ROG Strix X570-I Gaming, which is located near the rear I/O area, and uses a pair of fans for active cooling. The board uses a metal back-plate for additional heat dissipation. Networking options include 802.11ax Wi-Fi 6 WLAN, Bluetooth 5.0, and gigabit Ethernet, all driven by Intel-made controllers. USB connectivity includes a staggering six 10 Gbps USB 3.1 ports, one of which is type-C, and four 5 Gbps ports, two of which are located at the rear panel, four by headers. The rear I/O features the board's POST code display, and buttons for clear-CMOS, USB BIOS Flashback, and reset. There are power, POST retry, and failsafe boot buttons on the board. ASUS is pricing the ROG Crosshair VIII Impact around the USD $450-mark.
