Adamant Custom Ryzen 9 9900X3D RTX 5090 64GB DDR5 4TB NVMe 10TB HDD gaming PC

Built for heavy workloads

This system combines a twelve-core Ryzen 9 9900X3D processor with an RTX 5090 graphics card carrying 32GB of video memory. It targets professionals who run modelling, editing, rendering or AI learning tasks alongside high-end gaming. The 64GB of DDR5 memory and 4TB NVMe SSD provide the bandwidth and capacity those workloads demand.

Mid-tower foundation with room to expand

The Antec P20 case measures 469 x 220 x 490 mm and includes a 1200W 80 PLUS Gold power supply with a 140mm fan. A 240mm liquid cooler handles the CPU while three 120mm front fans move air through dust filters on the bottom, front and top. The motherboard offers four M.2 connectors, two SATA ports and internal bays for two 3.5-inch and two 2.5-inch drives, leaving space for additional storage beyond the supplied 10TB hard drive.

Sustained output under liquid cooling

The 240mm quiet-edition AIO keeps the twelve-core processor near its 5.50 GHz boost clock during long render or training sessions without the noise spikes of air coolers. The power supply’s Japanese main capacitor and full protection suite deliver stable current to the RTX 5090 and CPU simultaneously. Wi-Fi 7 and 2.5Gb Ethernet maintain network throughput when large datasets move between workstations.
