Built for professional modelling

This 2026 business desktop pairs a 24-core Intel Core i9-14900K with an Nvidia RTX PRO 4000 Blackwell graphics card carrying 24GB of memory. The combination targets engineers and designers who run SolidWorks, CAD, CAM and CAE workloads that demand both high single-thread frequency and certified professional drivers. Windows 11 Pro is pre-installed and the system is described as AI Ready.

Liquid-cooled Z790 platform with expandable storage

A 360mm AIO liquid cooler handles the CPU while the Antec P10 FLUX mid-tower case supplies three front 120mm fans, a rear 120mm fan and a PSU-shroud 120mm fan behind sound-dampening panels. The Z790 PRIME motherboard adds Wi-Fi 6 and BLUETOOTH 5.2, four SATA 6Gb/s ports and three M.2 connectors, of which one holds a 2TB Samsung 990 PRO NVMe drive and a 10TB HDD with 256MB cache occupies a 3.5-inch bay. Three further 2.5-inch bays and two additional M.2 slots remain open for future upgrades.

Sustained throughput for long compute runs

The CPU can reach 6.00 GHz with 36MB of L3 cache across 24 cores and 32 threads, while the 64GB of DDR5 memory — expandable to 192GB across four slots — feeds data to the GPU without throttling. An 850W 80 PLUS Bronze power supply with a 140mm fan and Japanese main capacitors delivers stable power under continuous load, and the liquid cooler keeps temperatures controlled during extended rendering or simulation sessions.

Questions about this item

How long can the 360 mm liquid cooler keep the Core i9-14900K at its 6.00 GHz boost before it has to throttle?

The 360 mm quiet-edition AIO is designed to absorb the sustained heat load of the 24-core CPU so it can hold higher clocks longer than an air cooler, but the exact time before thermal throttling begins depends on ambient temperature and case airflow.

What is the typical noise level of the 140 mm PSU fan and the three 120 mm front fans when the system runs a full-day render job?

The Thermaltake Smart 850 W PSU uses a 140 mm ultra-quiet fan and the Antec P10 FLUX case includes sound-dampening panels plus a fan-control button, so noise stays low even under continuous load.

Does the Z790 PRIME motherboard include Wi-Fi 6 and BLUETOOTH 5.2 so I can connect wireless peripherals without an extra card?

Yes, the board has built-in Wi-Fi 6 (802.11ax) and BLUETOOTH 5.2, plus Intel 2.5 Gb Ethernet for wired networking.
