What this system is

This is a new mid-tower gaming desktop built around a 24-core Intel Core Ultra 9 285K processor and 64GB of DDR5 memory. It ships with Windows 11 Pro installed and uses a 360mm liquid cooler on the CPU. The graphics card is an Nvidia GeForce RTX 5070 with 12GB of video memory. A 4TB Samsung 990 PRO NVMe drive provides primary storage.

Who it suits and who it does not

The 24-core CPU and 64GB of DDR5 suit creators who edit video, compile large codebases or run local AI workloads. The RTX 5070 handles 1440p gaming and GPU-accelerated rendering. Buyers who need more than 4TB of fast internal storage or who require a second graphics card for multi-GPU compute should look elsewhere. The motherboard offers four M.2 slots total, so additional NVMe drives can be added later.

Deciding specification

The CPU uses the LGA 1851 socket and the Z890 chipset, which together define the upgrade ceiling for both processor and memory. Maximum supported memory is 192GB across four DDR5 slots. The 850W 80 PLUS Bronze power supply delivers enough headroom for the current parts and a future GPU step-up within the same power envelope.

Questions about this item

Does the box include a monitor, keyboard and mouse, or must they be purchased separately?

The system ships with Windows 11 Pro installed but no monitor, keyboard or mouse are included; those peripherals must be bought separately.

The spec lists 64 GB DDR5 with four slots — should I choose the 64 GB configuration or add more later?

The board has four DDR5 slots supporting up to 192 GB total, so the 64 GB kit leaves three slots free for future expansion if workloads demand more memory.

What does the 12 GB RTX 5070 actually deliver for 4K gaming once the PC is assembled?

The RTX 5070 with 12 GB VRAM targets high-refresh 1440p and entry 4K gaming; actual frame rates depend on title settings and driver optimisation.
