The CPU is powered by a 6+1+1 phase design with Dr.MOS stages on a 6-layer PCB. The fast PCIe 5.0 M.2 slot suits next-generation SSDs, and the second M.2 slot runs at PCIe 4.0 x4. There are 13 USB connections in total: two USB 3.2 Gen1 Type-C (one rear, one front), five USB 3.2 Gen1 and six USB 2.0. Audio is a Realtek ALC897 with Nahimic.
Anyone building a compact AM5 PC that connects to the network by cable and does not need Wi-Fi. With two memory slots it pays to choose the right capacity up front, up to 128 GB. If wireless is needed later, a separate module can go into the M.2 Key E slot.
