Wired networking reaches 2.5Gbps while wireless uses Wi-Fi 7 (802.11be) with Bluetooth 5.4. Rear I/O includes one USB4 Type-C, one USB 3.2 Gen 2, four USB 3.2 Gen 1 and four USB 2.0 ports.

Compatibility checks before ordering

Verify that your workspace fits the 447 x 215 x 469 mm case dimensions and that your monitor inputs match the RTX 5090 video outputs. The 1200W 80 PLUS Gold power supply requires a suitable mains circuit. Ensure any extra memory you add is DDR5 and that replacement drives match the available M.2 or 3.5-inch bays.
