24-Core i9-14900K Workstation

This new business desktop tower pairs a 24-core Intel Core i9-14900K processor with 64GB of DDR5 memory and an NVIDIA RTX A4000 graphics card. A 360mm liquid cooler manages CPU thermals inside an Antec P20 mid-tower case. The system ships with Windows 11 Pro installed and includes Wi-Fi 6 and BLUETOOTH 5 connectivity.

Professionals needing GPU compute and fast storage

The configuration suits engineers running SolidWorks, CAD, CAM or CAE workloads that benefit from the RTX A4000 and dual 4TB NVMe SSDs reaching 7450 MB/s read speeds. A 10TB hard drive adds bulk capacity for project archives. Buyers who need more than 64GB of memory or a second graphics card should look at alternative configurations.

192 GB maximum DDR5 capacity

Four memory slots support up to 192 GB of DDR5, so the installed 64 GB can be expanded without replacing modules. The Z790 motherboard provides four M.2 connectors and six SATA ports for additional drives. A Thermaltake 850W 80 PLUS Bronze power supply delivers power to all components.

Questions about this item

How can I verify the 24-core i9-14900K is running at its 3.2 GHz base and 6.00 GHz boost after assembly?

Open Task Manager’s Performance tab to confirm 24 cores and 32 threads are detected, then run a CPU stress utility and watch the frequency climb toward 6.00 GHz while the 360 mm liquid cooler keeps temperatures in check.

What ships inside the Antec P20 case and which parts must I source myself?

The tower arrives fully assembled with the Z790 AORUS motherboard, 64 GB DDR5, two 4 TB Samsung 990 PRO NVMe drives, a 10 TB HDD, RTX A4000 graphics, 850 W PSU, 360 mm AIO cooler, Wi-Fi 6 and BLUETOOTH 5 — only a display, keyboard and mouse are needed separately.

Which storage tier should I pick if the workload demands sustained 7 450 MB/s reads?

The dual 4 TB Samsung 990 PRO NVMe SSDs deliver up to 7 450 MB/s sequential read and 6 900 MB/s write, so the standard 8 TB NVMe configuration already satisfies that requirement without any upgrade.
