PCIe Slots: 3 × PCIe x16

PCI_E1: PCIe 5.0 ×16 (Ryzen 9000/7000), PCIe 4.0 ×8 (Ryzen 8700/8600/8400), PCIe 4.0 ×4 (Ryzen 8500/8300)

PCI_E2: PCIe 3.0 ×1 (Chipset)

PCI_E3: PCIe 4.0 ×4 (Chipset)

Audio: Realtek® ALC4080, 7.1‑channel USB high‑performance audio, up to 32‑bit/384 kHz (front), S/PDIF output

Storage: 4 × M.2 • M.2_1 (CPU): PCIe 5.0 ×4 (Ryzen 9000/7000), PCIe 4.0 ×4 (Ryzen 8000) • M.2_2 (CPU): PCIe 5.0 ×4 (Ryzen 9000/7000), PCIe 4.0 ×4 (Ryzen 8700/8600/8400) *Unavailable with Ryzen 8500/8300 • M.2_4 (Chipset): PCIe 4.0 ×4 (2280/2260) 4 × SATA 6G

Bandwidth Notes: USB 40Gbps Type‑C ports and M.2_2 share PCIe 5.0 ×4 bandwidth. Both operate at PCIe 5.0 ×2 when M.2_2 is populated. BIOS can switch M.2_2 to PCIe 5.0 ×4 (disables USB 40Gbps Type‑C). USB4 host controller supports PCIe 4.0 ×4.
