Dual RTX 5090 Workstation

The ArsenalPC ES620 is a liquid-cooled desktop built around an AMD Ryzen 9 9900X 12-core processor running at 4.4GHz. It pairs 256GB of DDR5 memory with two GeForce RTX 5090 graphics cards, each equipped with 64GB of GDDR7 video memory. An 8TB NVMe SSD array in RAID configuration provides the primary storage volume. The system ships with Windows 11 Pro installed and includes a 1600W power supply.

Professionals prototyping large AI models

This configuration suits developers and researchers who need combined GPU memory capacity for training or inference workloads that exceed a single card's frame buffer. Content creators rendering complex scenes or running multiple GPU-accelerated applications simultaneously will also benefit from the dual-GPU layout. Buyers whose workflows fit comfortably within a single RTX 5090 or who rely on CPU-bound tasks that do not scale across two graphics cards should consider a single-GPU alternative.

256GB DDR5 system memory

The installed 256GB DDR5 kit determines the maximum dataset size that can reside in main memory before swapping to the NVMe array. Workloads that require larger host memory footprints will be constrained by this capacity, while tasks that fit within it can take full advantage of the dual-GPU compute resources and high-speed storage.

Questions about this item

Will the 360 mm liquid cooler fit in a standard mid-tower case?

The cooler is already installed in the ES620 chassis, so no separate case clearance check is needed.

What PCIe slot spacing do the dual RTX 5090 cards require on the motherboard?

The two RTX 5090 GPUs occupy adjacent full-length slots; the board and chassis are pre-configured for that spacing.

How often should the 360 mm liquid cooler be serviced or refilled?

The loop is factory-sealed and maintenance-free for the life of the system.
