Form Factor: microATX (The size, arrangement, and physical configuration of the product.)
Processor Socket: Socket AM5 (LGA 1718) (Type of pin configuration that connects a CPU to a computer’s motherboard.)
Wireless Networking Standard: Wi-Fi 6 (The wireless networking standard used by the device. Each iteration of the standard developed by the Wi-Fi Alliance corresponds to an existing IEEE 802.11 protocol; for example, standard 802.11ac (or AC) is termed Wi-Fi 5. Refers specifically to the standard the device is designed to use, but ultimately determines product interoperability and backward compatibility including previous versions.)

Number Of PCI-E x16 Slots: 1
Number Of Memory Slots: 4
Connectivity
Wireless Connectivity: None (The manner in which a device sends data to another device over a short distance without the use of wires or cables.)
Wireless Networking Standard: Wi-Fi 6 (The wireless networking standard used by the device. Each iteration of the standard developed by the Wi-Fi Alliance corresponds to an existing IEEE 802.11 protocol; for example, standard 802.11ac (or AC) is termed Wi-Fi 5. Refers specifically to the standard the device is designed to use, but ultimately determines product interoperability and backward compatibility including previous versions.)
Ports
USB Ports: 4 x USB-A 2.0, 7 x USB-A 3.1 (The number and type of USB ports the product has.)
Number of Audio Channels: 7.1 (The number of discrete channels of sound output. This can be a single number or multiple numbers separated by decimal(s). The first number is the primary, horizontally directed audio channels. The number after the first decimal, if applicable, is the number of subwoofer outputs or channels. The number after the second decimal, if applicable, is the number of height or atmospheric channels designed to immerse the listener by producing overhead sound effects.)
Dimensions
Product Length: 279.40 millimeters (The out of box length of the item. Length is measured as the longest dimension of the item.)
Product Width: 254.00 millimeters (The out of box width of the item. Width is measured as the horizontal distance from one side of the item to the other as it would be primarily used or placed.)
Product Weight: 35.2 ounces (The out of box weight of the item.)
Memory
Maximum Memory Supported: 128 gigabytes
Memory Type Supported: DDR5 SDRAM
Memory Format Supported: UDIMM (Memory module size that will fit with the device.)
Memory Speeds Supported: 2 DIMMs, Dual Channel DDR5 – 8000+ MT/s (OC) (The RAM's bandwidth rating supported by the device. The number refers to transfer speed. For example, 12800 would indicate that the memory has a theoretical bandwidth of 12,800 megabytes per second (MBs). The higher the number, the faster the speed.)
Memory Slot Type: 288-pin DIMM
Features
RAID Support: RAID 0 (A Redundant Array of Independent Disks (RAID) includes a collection of separate disks that your computer recognizes as one disk unit. Each configuration offers a different level of mirroring, striping and read/write speeds.)
