Dual RTX 5090 AI workstation

This ArsenalPC MES2X desktop pairs an AMD Ryzen 9 9900X 12-core processor at 4.4GHz with dual GeForce RTX 5090 graphics cards. The 256GB DDR5 memory and 4TB NVMe SSD support large-model training, rendering and simulation workloads. Liquid cooling and a 1600W power supply sustain heavy continuous compute. Windows 11 Home is pre-installed.

Motherboard AM5 dual-slot spacing check

Verify that your workload software can scale across two RTX 5090 GPUs and that the AM5 motherboard provides sufficient PCIe lane allocation for both cards. Confirm the 288-pin DDR5 slots are populated as specified and that the 2.5G Ethernet plus wireless connectivity meet your network infrastructure. The 1600W unit requires a suitable mains circuit.

360mm liquid loop and connectivity

A 360mm liquid cooler handles the Ryzen 9 9900X thermal output while the dual GPU layout occupies two full-length slots. Integrated audio, 2.5G Ethernet and Wi-Fi are built into the AM5 motherboard. The black MES2X chassis houses the 4TB NVMe drive and 256GB DDR5 kit. All components run on the 1600W supply under Windows 11 Home.
