Custom Workstation Build

This liquid-cooled business desktop ships with a 24-core Intel Core i9-14900K processor and 192GB of DDR5 memory. It combines an 8TB NVMe array with a 10TB hard drive for high-capacity storage. The Nvidia RTX A400 GPU provides four Mini DisplayPort outputs for multi-monitor productivity setups. Windows 11 Pro is pre-installed on the tower chassis.

Quiet Liquid Cooling & 850W Bronze PSU

A 360mm quiet-edition AIO cooler handles the CPU thermal load while the Antec P10 FLUX case uses sound-dampening panels and multiple 120mm fans for airflow. The Thermaltake Smart 850W 80 PLUS Bronze unit supplies power with a 140mm low-noise fan and Japanese main capacitors. Integrated 2.5Gbps LAN, Wi-Fi 6 and Bluetooth 5.2 manage connectivity without adding acoustic noise.

Sustained Load Stability

The 24-core CPU reaches up to 6.00 GHz across 32 threads with 36MB L3 cache for prolonged compute tasks. Dual Samsung 990 PRO SSDs deliver sequential reads up to 7450 MB/sec and writes up to 6900 MB/sec over PCIe 4.0x4. The Z790 PRIME motherboard offers three M.2 slots and four SATA ports for storage expansion. Realtek 7.1 surround audio supports monitoring during long rendering sessions.

Questions about this item

How is the 360 mm liquid cooler installed and what step is often missed?

The cooler mounts on the LGA 1700 socket using the supplied bracket; the step often missed is removing the protective film from the cold-plate before seating it on the CPU.

What maintenance will the 360 mm liquid cooler and 850 W power supply need later?

Check the radiator fins for dust every six months and verify the 140 mm PSU fan spins freely; the sealed AIO loop requires no fluid top-up.

What limit appears first when the i9-14900K runs sustained loads at up to 6.00 GHz?

The 360 mm radiator reaches its heat-dissipation ceiling before the CPU hits its thermal throttle point, so coolant temperature becomes the limiting factor.
