Ready-to-use desktop workstation

This system ships fully assembled with Windows 11 Pro installed, a 20-core Intel Core Ultra 7 265K processor, 32 GB of DDR5 memory and a 4 TB Samsung 990 PRO NVMe drive. Liquid cooling keeps the CPU quiet under sustained workloads. It targets professionals who need a capable machine without building one themselves.

Integrated graphics limit

The PC relies on the processor's integrated graphics with HDMI and DisplayPort outputs, so it handles office suites, video playback and light creative tasks but not modern 3D titles or GPU-accelerated rendering. Buyers who need discrete graphics performance should plan a separate card upgrade.

Upgrade path and wiring

The motherboard provides four DDR5 slots supporting up to 192 GB and four M.2 connectors for additional NVMe storage. A 750 W 80 PLUS Bronze unit powers the build; adding a high-end graphics card will require checking cable clearance and power headroom. Front-panel USB 3.2 Gen 2 Type-C and Thunderbolt 4 on the rear simplify peripheral connections.

Questions about this item

Will the 240 mm liquid cooler fit inside the Antec P20 mid-tower case?

The Antec P20 mid-tower measures 469 x 220 x 490 mm and supports a 240 mm radiator, so the supplied AIO cooler fits without modification.

How do I seat the LGA 1851 CPU into the Z890 TUF motherboard without bending pins?

Align the triangle marker on the Intel Core Ultra 7 265K with the socket corner, lower it straight down, then close the retention lever — forcing it sideways damages the 1851 contacts.

When should I plan to replace the 750 W Thermaltake PSU in this build?

The Thermaltake Smart 750 W 80 PLUS Bronze unit uses a Japanese main capacitor rated for long life; typical replacement is after seven to ten years of continuous use.
