Questions about this item

What comes in the box and do I need to buy a monitor, keyboard or mouse separately?

The tower ships with Windows 11 Pro installed, a 1200 W 80 PLUS Gold PSU, 360 mm liquid CPU cooler, Wi-Fi 6E and Bluetooth5.3 antennas, and a UK power cable. Monitor, keyboard and mouse are not included.

Should I choose the 32 GB DDR5 configuration or upgrade to the 192 GB maximum?

32 GB DDR5 handles current games and creative workloads well; the Z890 board supports up to 192 GB across four slots if you later need more capacity for heavy rendering or virtualization.

What does the RTX 5090 32 GB GPU mean for 4K gaming frame rates?

The RTX 5090 with 32 GB VRAM drives high frame rates at 4K ultra settings in modern titles and provides headroom for AI‑accelerated workflows and future game engines.
