ArsenalPC ES620 dual GPU workstation

This desktop pairs a 12-core Ryzen 9 9900X running at 4.4 GHz with dual RTX 5090 graphics cards, each equipped with 64 GB of GDDR7 memory. The 256 GB DDR5 system memory and 4 TB NVMe SSD provide capacity for large datasets and fast asset streaming. It targets researchers, developers and creators who need local AI compute alongside high-end gaming performance.

Sustained load behaviour with liquid cooling

A 360 mm liquid cooler handles the CPU while the dual GPU configuration distributes rendering and compute workloads across both cards. The 1600 W power supply feeds the complete platform under continuous stress. Integrated 2.5G Ethernet and wireless connectivity maintain network throughput during long training runs or multiplayer sessions without thermal throttling.

Upgrade path from single GPU systems

Builders moving from a single RTX card gain a second 64 GB GPU, doubling VRAM for larger models and enabling multi-GPU frameworks. The 256 GB DDR5 capacity exceeds typical consumer platforms, removing memory bottlenecks in data preparation. Buyers who need more than two GPUs or require ECC memory for mission-critical workloads should evaluate rackmount alternatives.

Questions about this item

How much power does the 1600W supply draw when both RTX 5090 cards and the Ryzen 9 9900X run flat out all day?

The 1600W unit is sized to feed dual RTX 5090 GPUs and a 12-core Ryzen 9 9900X simultaneously, with the 360mm liquid loop moving heat out of the case so the system stays stable during extended AI or rendering loads.

Does the ArsenalPC ES620 include a monitor, keyboard and mouse so I can start working immediately?

The workstation arrives with Windows 11 Pro installed and tested, but peripherals are not included; you will need to provide your own display, keyboard and mouse to begin using the dual RTX 5090 system.

Can I keep my older PCIe 3.0 NVMe drive and add it alongside the 4TB NVMe SSD already installed?

The AM5 platform supports PCIe 4.0 and 5.0 storage, so a PCIe 3.0 drive will work at its native speed when installed in an available M.2 slot, letting you retain existing data without bottlenecking the primary 4TB NVMe volume.
