Workstation-Grade Gaming Desktop

This Adamant Custom system pairs a 12-core Ryzen 9 9900X3D processor with 128GB of DDR5 memory and an RTX 5070 Ti graphics card. It ships with Windows 11 Pro installed on a 1TB Samsung 990 PRO NVMe drive. The configuration targets professionals who need rendering, modelling or AI learning capability alongside high-refresh gaming performance.

Sustained Load Behaviour

The 240mm quiet-edition liquid cooler keeps the CPU near its 5.50 GHz boost ceiling during long compile or render sessions without thermal throttling. The Thermaltake Smart 850W 80 PLUS Bronze power supply delivers stable current through extended GPU compute workloads. All 12 cores and 24 threads remain available for parallel tasks such as video encoding or large dataset processing.

Thermals Noise and Power

Liquid cooling and the PSU's 140mm fan combine for low acoustic output in typical office or studio environments. The 850W unit operates efficiently at normal system draw thanks to its Bronze certification and Japanese main capacitor. Component temperatures stay controlled inside the Corsair 4000D chassis with its tempered glass panel and optimised airflow path.

Questions about this item

How loud is the 240mm liquid cooler and 140mm PSU fan when the Ryzen 9 9900X3D runs all day?

The CPU uses a 240mm Quiet Edition AIO and the 850W PSU has a 140mm ultra-quiet fan, both designed for low noise under sustained load.

What display cable and monitor port do I need for the RTX 5070 Ti 16GB?

The GPU uses a PCI Express x16 slot internally; you must supply a monitor with a compatible input such as HDMI or DisplayPort and the matching cable.

Will my existing SATA SSDs or 3.5-inch hard drives fit inside the Corsair 4000D case?

The case provides two internal 3.5-inch bays and two 2.5-inch bays with SATA 6Gb/s ports on the motherboard, so older drives install directly.
