4× NVIDIA RTX 5090 — 128GB aggregate GDDR7
AMD Threadripper PRO 7995WX (96-core)
512GB DDR5 ECC (8-channel)
16TB PCIe Gen5 NVMe (RAID)
Overview
This flagship workstation places four NVIDIA RTX 5090 GPUs alongside a 96-core AMD Threadripper PRO processor and 512GB of ECC memory under a liquid-cooling design engineered for the platform's substantial power and thermal load. Nexus Compute sources, assembles, and stress-tests the complete configuration through authorized channels and delivers it warranty-backed and production-validated.
Who This Solution Is For
Business Benefits
Cluster-class on one node
Four 5090s deliver 128GB of aggregate VRAM for large training and multi-experiment work without standing up a cluster.
Engineered power and thermals
Dual high-wattage PSUs and a validated liquid loop handle the platform's roughly 2,300W of GPU draw reliably.
Stress-tested before delivery
We run the full four-GPU configuration under load so power, cooling, and drivers are proven before it ships.
Typical Business Use Cases
Multi-GPU distributed training on a single node
Large-model fine-tuning with data parallelism
High-volume batch inference and rendering
Concurrent multi-user research workloads
Industry Applications
Technical Overview
Four NVIDIA RTX 5090 GPUs (128GB aggregate GDDR7) run on an AMD Threadripper PRO 7995WX with 96 cores and 128 PCIe Gen5 lanes distributing bandwidth across all four cards. Dual 2400W power supplies and a custom liquid-cooling loop sustain the four-GPU load that exceeds any single-PSU or air-cooled design.

Frequently Asked Questions
Can this replace a small GPU cluster?
For many teams, yes — four 5090s provide 128GB of aggregate VRAM and strong data-parallel training throughput on a single node, avoiding the networking and orchestration overhead of a cluster.
How is the power delivery handled?
Four 575W GPUs require roughly 2,300W on their own, so we configure dual 2400W Titanium power supplies for a 4800W total system budget with headroom.
Is air cooling an option at this density?
No. Four 5090s in one chassis generate thermal load that requires a liquid-cooling design to run reliably without throttling; we validate the loop under full load before shipping.
