Built for AI workloads and high-refresh gaming

This desktop pairs a 20-core Intel Core Ultra 7 265K with an Nvidia GeForce RTX 5090 32GB GPU and 64GB DDR5 memory. The platform targets creators running local inference, 3D rendering or simulation alongside competitive gaming at 4K. Windows 11 Pro ships pre-installed on a 4TB Samsung 990 PRO NVMe drive.

Liquid cooling sustains clocks during long renders

A 240mm quiet-edition AIO keeps the CPU near its 5.50 GHz boost across extended compile or training sessions. The Thermaltake Toughpower 1000W 80 PLUS Gold unit delivers stable power with Japanese capacitors and a 140mm low-noise fan. Front-panel 120mm intake fans and full dust filtration maintain airflow inside the Antec P20 mid-tower.

Replaces a workstation-plus-gaming rig combo

Consolidating a 30 MB L3 cache CPU, 32GB VRAM GPU and 7450 MB/s storage into one chassis removes the need for separate machines. The Z890 TUF motherboard adds Thunderbolt 4, Wi-Fi 7 and four M.2 slots for future expansion. Buyers needing more than 192 GB RAM or dual-GPU scaling should look elsewhere.

Questions about this item

How loud does the 240mm liquid cooler and 140mm PSU fan get under sustained load?

The 240mm Quiet Edition AIO cooler and 140mm PSU fan are both specified for low noise operation, keeping acoustic output minimal during extended gaming or rendering sessions.

Does the Z890 motherboard include Wi-Fi 7 and Bluetooth 5.4 so I do not need separate adapters?

Yes, the board integrates Wi-Fi 7 2x2 (802.11be) and Bluetooth 5.4, providing high-speed wireless and peripheral connectivity out of the box.

Can I keep my existing SATA SSDs or HDDs and connect them to this build?

The motherboard provides four SATA 6Gb/s ports and the case includes two 3.5"/2.5" internal bays, so current SATA drives install directly.
