Built for AI workstation workloads

This desktop pairs a 12-core Ryzen 9 9900X3D with 128GB DDR5 and an RTX 5090 32GB GPU. The 8TB NVMe array uses two Samsung 990 PRO drives in a Cooler Master HAF 500 tower. Windows 11 Pro ships pre-installed for immediate deployment.

Liquid cooling and high-wattage power

A 240mm Quiet Edition AIO handles the CPU while a Thermaltake Toughpower 1200W 80 PLUS Gold PSU feeds the GPU and motherboard. Front 200mm ARGB fans and a rear 120mm fan move air through the tempered-glass chassis. Rear I/O includes USB4 40Gbps and Wi-Fi 7.

128GB DDR5 defines multitasking ceiling

Four slots hold the current 128GB kit with headroom to 192GB maximum supported. Builders who need more memory capacity must populate the remaining slots. Buyers who want more storage must add drives to the two internal 3.5-inch bays.

Questions about this item

Will the 240 mm liquid cooler need coolant replacement or pump service?

The 240 mm Quiet Edition AIO is a sealed unit that does not require coolant replacement; pump service is not expected under normal use.

Which component hits its limit first during sustained all-core workloads?

The CPU power draw and thermals under prolonged 12-core load will reach the cooler capacity before the 1200 W 80 PLUS Gold PSU or GPU limits.

How loud and hot does the system get when running 24/7?

The 140 mm PSU fan and 200 mm front ARGB fans run at low RPM; liquid CPU cooling keeps the Ryzen 9 9900X3D near 4.4 GHz base without thermal throttling.
