X570S board with eight SATA ports, dual LAN and 7.1 audio bundled with an 8-core 3.8 GHz 105 W Ryzen 7 5800X CPU
This bundle pairs an ASUS ROG Crosshair VIII Dark Hero motherboard with an AMD Ryzen 7 5800X 8-Core 3.8 GHz 105W processor. The board uses the AMD X570 chipset and AM4 socket, supporting Ryzen 5000, 4000 G-Series, 3000 and 2000 Series desktop CPUs. It is built for enthusiasts who want a high-end platform for gaming or content creation with extensive connectivity options.
The motherboard provides two PCIe 4.0 x16 slots that run at x16 or dual x8 with Ryzen 5000 or 3000 Series processors, plus one PCIe 4.0 x1 slot and one PCI Express 3.0 x16 slot. Eight SATA 6Gb/s ports and one M.2 socket supporting 2242, 2260 and 2280 drives give plenty of room for SSDs and hard drives. Builders needing multiple full-length PCIe 4.0 x16 devices or more than one M.2 slot should consider a different platform.
The board includes a single M.2_1 socket with M Key, accepting Type 2242, 2260 and 2280 drives in PCIe 4.0 x4 or SATA modes. This single high-speed M.2 connection is the limiting factor for fast storage expansion. If the build requires more than one primary M.2 drive, this motherboard will not meet that requirement.

The board uses standard ATX mounting holes and requires a 24-pin ATX plus two 8-pin EPS connectors for the 105W processor.
Update the BIOS to a version that supports Ryzen 5000 series before first boot, otherwise the system will not post with the 3.8 GHz 8-core CPU.
Replace the coin cell when the system loses date and time settings after being unplugged, typically after several years of use.
