Intel NUC 11 Extreme Gaming Desktop

This Intel NUC 11 Extreme system ships as a complete gaming desktop with an 8-core Core i9-11900KB processor, a Radeon RX 580 8G graphics card and 32GB of DDR4 3200MHz memory. A 1TB PCIe 4.0 NVMe SSD and Windows 11 Home are pre-installed in an 8-litre ITX chassis powered by a 650W 80 Plus Gold supply.

Check PSU headroom and case clearance before

The 650W 80 Plus Gold unit feeds the CPU, the discrete Radeon RX 580 and all onboard devices, so confirm your planned upgrades stay within that budget. The 357 x 189 x 120 mm ITX enclosure limits graphics-card length and cooler height, and the board uses DDR4 slots only, so memory must match that generation.

Bundled Wi-Fi 6E and Bluetooth adaptors

An Intel Wi-Fi 6E AX210 module provides wireless networking and Bluetooth without occupying a separate slot. Windows 11 Home 64-bit is already activated, so the machine is ready to use once power and a display are connected.

Questions about this item

Does the NUC11BTMi9 ship with the Aigo RX580 8G graphics card and Windows 11 Home already installed?

Yes, the system arrives fully assembled with the Aigo RX580 8G GPU installed and Windows 11 Home 64-bit pre-loaded, so no separate GPU purchase or OS installation is required.

Should I choose the 32 GB DDR4 3200 MHz kit or look for a larger capacity?

The board is populated with 2×16 GB modules for 32 GB total at 3200 MHz; this fills both SO-DIMM slots, so any increase would require replacing the existing pair.

What does the 4.9 GHz turbo figure mean for everyday gaming on the Core i9-11900KB?

The 8-core i9-11900KB can boost up to 4.90 GHz on light-threaded loads, giving strong single-thread frame rates, while the 650 W 80 Plus Gold PSU and 8-litre ITX chassis keep sustained clocks stable during extended sessions.
