Key strengths
4 M.2 storage positions and 2 SATA connectors provide several drive-connection options.
1 × Realtek 2.5Gb Ethernet provides a wired network connection.
Before you buy
Using M.2_3 disables PCIEX16(G4)_1 and PCIEX16(G4)_2. M.2_4 is PCIe 3.0 x2 and becomes unavailable when either SATA port is used. Ryzen 8000 changes M.2_1 from PCIe 5.0 to PCIe 4.0.
Check the exact processor, BIOS and memory kit before purchase. The 256 GB ceiling and listed overclocking profiles are configuration limits, not a tested build guarantee.
The inspected specification does not verify an included wireless module; plan around the wired connection unless the exact retail configuration confirms one.

Specifications vary by CPU types. PCIEX16(G4)_1 and PCIEX16(G4)_2 share bandwidth with M.2_3. PCIEX16(G4)_1 and PCIEX16(G4)_2 will be disabled when M.2_3 runs. - To ensure compatibility of the device installed, please refer to https://www.asus.com/support/download-center/ for the list of supported peripherals.
Using M.2_3 disables PCIEX16(G4)_1 and PCIEX16(G4)_2. M.2_4 is PCIe 3.0 x2 and becomes unavailable when either SATA port is used. Ryzen 8000 changes M.2_1 from PCIe 5.0 to PCIe 4.0.
