AI Workstation for Development

The ABS Kalyron Ruby is a liquid-cooled tower workstation built around a 24-core AMD Ryzen Threadripper PRO 9965WX and an ASUS TUF Gaming GeForce RTX 5090 with 32 GB GDDR7 memory. It ships with 128 GB DDR5 ECC registered memory and 6 TB of PCIe 5.0 NVMe storage across two drives. Ubuntu comes pre-installed on a system assembled in the USA and TAA compliant.

Sustained Load Behaviour

Liquid cooling on the CPU allows the 24-core Threadripper PRO to maintain high frequencies during extended AI training or inference runs without thermal throttling. The 2000 W 80 PLUS Platinum power supply delivers stable current to the GPU and all expansion slots under continuous maximum draw. Seven PCIe 5.0 x16 slots provide bandwidth headroom for additional accelerators or high-speed networking cards.

32 GB GPU VRAM Decides Fit

The single specification that determines suitability is the 32 GB GDDR7 frame buffer on the RTX 5090, which sets the maximum model size that fits in GPU memory for local inference or training. Buyers who need larger models in VRAM cannot meet that need with this configuration. The eight DIMM slots support up to 2 TB of system memory for data sets that exceed GPU capacity.

Questions about this item

How much power does the 2000W 80 PLUS Platinum PSU draw when the Threadripper PRO 9965WX and RTX 5090 run sustained AI workloads?

The 2000W Platinum unit is sized for the 24-core Threadripper PRO 9965WX and ASUS TUF RTX 5090 32GB GDDR7 combination under continuous load, with liquid cooling on the CPU to manage thermals.

Which display cables and monitor inputs are needed to use the ASUS TUF RTX 5090 32GB GDDR7?

The RTX 5090 provides standard DisplayPort and HDMI outputs; you must supply a compatible cable and a monitor that accepts one of those interfaces.

Can I keep my existing SATA or SAS drives and add them to the 6TB of installed PCIe 5.0 NVMe storage?

Yes — the platform includes SATA and SAS interfaces alongside the 2TB OS and 4TB data NVMe drives, so older drives can be installed in the available bays.
