Built for heavy workloads

This desktop combines a 24-core Intel Core i9-14900K with an Nvidia GeForce RTX 5090 32GB GPU and 128GB DDR5 memory. It targets creators and engineers who need strong single-thread speed and massive parallel throughput for rendering modelling and AI learning tasks. The system ships with Windows 11 Pro on a 2TB Samsung 990 PRO NVMe drive. Liquid cooling keeps the CPU stable under sustained load.

Moving up from lesser configurations

Builders who hit memory or GPU VRAM limits on 64GB or 32GB systems will benefit from the 128GB DDR5 capacity and 32GB frame buffer. The jump is worth it when projects exceed 64GB of active data or when GPU compute queues stall on smaller cards. The Z790 TUF motherboard supports up to 192GB total so further expansion is possible without a platform change.

Platform limits to consider

The LGA 1700 socket and Z790 chipset cap memory at 192GB and PCIe at 4.0x4 for the primary M.2 slot. The 1200W 80 PLUS Gold PSU delivers ample headroom for this build but leaves no margin for a second high-end GPU. Wi-Fi 6 and Bluetooth 5.2 provide modern wireless connectivity while the 2.5Gb Ethernet port handles wired traffic.

Questions about this item

Will the 469 mm deep Antec P20 case fit on my desk?

The case measures 469 mm deep, 220 mm wide and 490 mm high; allow a few centimetres extra for rear cables and front-panel access.

How is the 360 mm liquid cooler mounted, and what step do builders often miss?

The 360 mm radiator fits the top of the P20 case with three 120 mm fans; the step often missed is removing the protective film from the cold-plate before seating it on the i9-14900K.

When will the 1200 W 80 PLUS Gold PSU need its fan or capacitors checked?

The Thermaltake Toughpower uses a 140 mm fan and Japanese main capacitors; plan a dust clean every 12 months and a capacitor health check after roughly five years of heavy load.
