24-Core i9-14900K Workstation

This Adamant Custom tower pairs a 24-core Intel Core i9-14900K with 192GB DDR5 and an Nvidia GeForce RTX 5090 32GB GPU. The configuration targets creators and engineers who need sustained multi-thread throughput for rendering, modelling and AI learning workloads alongside high-frame-rate gaming. Windows 11 Pro 64-bit is pre-installed.

Z790 Platform With 360mm Liquid Cooling

The Z790 PRIME motherboard provides four DDR5 slots fully populated at the 192GB maximum, three M.2 connectors and 2.5Gb Ethernet plus Wi-Fi 6 and BLUETOOTH 5.2. A 360mm Quiet Edition AIO cooler handles the CPU thermal load, while the Thermaltake Toughpower 1200W 80 PLUS Gold PSU with Japanese main capacitors delivers stable power to the GPU and all peripherals.

Sustained Load Behaviour

Under continuous compute or render tasks the liquid cooler maintains lower CPU temperatures than air alternatives, allowing the 24 cores to hold higher boost frequencies for longer periods. The 1TB Samsung 990 PRO PCIe 4.0x4 SSD sustains sequential reads up to 7450 MB/sec and writes up to 6900 MB/sec, keeping large asset streams fed to the RTX 5090 without throttling.

Questions about this item

At what clock speed does the i9-14900K hit its thermal ceiling under a continuous all-core load?

The 24-core i9-14900K is rated to boost up to 6.00 GHz, and the 360 mm quiet-edition liquid cooler is sized to keep it there during sustained workloads.

How loud does the 360 mm AIO and the 1200 W Gold PSU get when the system runs flat-out for hours?

The AIO uses a quiet-edition pump and radiator fans, while the Thermaltake Toughpower 1200 W unit has a 140 mm fan designed for low-noise operation at high load.

Which display cables and monitor inputs are needed to use the RTX 5090 32 GB right out of the box?

The RTX 5090 provides standard DisplayPort and HDMI outputs, so a monitor with a matching DisplayPort or HDMI input and the corresponding cable are all that is required.
