It is based on the AMD B850 chipset and suits everyday PCs, work systems and gaming builds. The board has four DDR5 slots for up to 256GB of memory, a PCIe 5.0 x16 graphics slot, three M.2 slots (one of them PCIe 5.0) and four SATA ports. It also brings 2.5 Gigabit LAN, Wi-Fi 6E and Bluetooth 5.2, plus HDMI and DisplayPort outputs for the processor's integrated graphics. 
Key features- 8+2+1 phase power - Dr.MOS stages for VCore, SOC and MISC and a 6-layer PCB deliver stable power to the processor and memory.
- DDR5 up to 8000+ (OC) - Four dual-channel DDR5 slots for up to 256GB with XMP and EXPO profile support. The board also supports unbuffered ECC memory.
- PCIe 5.0 for graphics and storage - A PCIe 5.0 x16 slot with 15μ gold contacts and a Blazing M.2 PCIe Gen5x4 slot at up to 128Gb/s. Two Hyper M.2 PCIe Gen4x4 slots and four SATA3 ports with RAID complete the storage.
- Wired and wireless networking - Dragon 2.5G LAN based on Realtek RTL8125BG, a 2x2 Wi-Fi 6E module and Bluetooth 5.2. Two antennas are included.
- Plenty of USB - The rear panel has USB 3.2 Gen2 Type-C and Type-A, two USB 3.2 Gen1 and four USB 2.0 ports. Internal headers add a front USB-C port and more USB ports for the case.
