14-core liquid-cooled workstation

This business desktop pairs a 14-core Intel Core Ultra 5 245K processor with 64GB of DDR5 memory and an Nvidia RTX A400 graphics card driving four Mini DisplayPort outputs. It targets professionals who need stable multi-display output for media work, CAD review or AI-assisted workflows in a quiet chassis.

240mm AIO and 750W Bronze PSU

A 240mm quiet-edition liquid cooler handles the CPU while the case uses three 120mm front fans, one 120mm rear fan and a 120mm PSU shroud fan alongside a 140mm power-supply fan. The Thermaltake Smart 750W 80 PLUS Bronze unit supplies power with over-voltage, under-voltage, over-power and short-circuit protection.

Antec P10 FLUX with sound dampening

The mid-tower case includes a sound-dampening panel, front I/O with two USB 3.0 ports and a fan-control button, plus internal bays for three 3.5-inch and three 2.5-inch drives. The Z890-PLUS TUF motherboard adds Thunderbolt 4, USB 20Gbps and 10Gbps ports, four SATA and four M.2 connectors, 2.5G Ethernet, Wi-Fi 7 and Bluetooth 5.4.

Questions about this item

How do I install the 240 mm AIO liquid cooler and what step do builders often miss?

Mount the radiator with tubes at the bottom or side so the pump stays below the highest coolant point; the step most people miss is removing the protective film from the cold-plate before seating it on the LGA 1851 CPU.

Which components in this workstation will need replacement first under heavy daily use?

The 10 TB HDD with 256 MB cache and the 750 W 80 PLUS Bronze PSU are the mechanical and electrolytic parts most likely to wear out before the solid-state CPU, GPU or DDR5 memory.

What thermal limit appears first when the 14-core Core Ultra 5 245K runs sustained all-core loads?

The 240 mm Quiet Edition AIO reaches its heat-rejection capacity before the processor hits its 5.20 GHz turbo ceiling, so coolant temperature becomes the limiting factor.
