RTX PRO 6000 Blackwell workstation, up to 192GB of VRAM.
The JNCS AI PRO runs one or two NVIDIA RTX PRO Blackwell GPUs, from the 32GB RTX PRO 4500 to the 96GB RTX PRO 6000, on a Threadripper 9000 processor and an ASUS Pro WS TRX50-SAGE board with quad-channel registered ECC memory. It is sized for larger models, longer context windows, and multi-day jobs.

What 48GB to 192GB of VRAM runs
Total VRAM sets the largest model that can be loaded.
Model weights occupy roughly parameters × bits per weight ÷ 8. A 70-billion-parameter model at 4-bit quantization is about 35GB of weights; with context and runtime overhead it requires approximately 48GB of VRAM. Context length and batch size add to every figure below.
48GB: one RTX PRO 5000
A 70B-class model at 4-bit quantization requires approximately 48GB of VRAM.
96GB: one RTX PRO 6000
A 70B-class model fits in 96GB at 8-bit quantization, with the whole model on a single GPU.
144GB to 192GB: two GPUs
Two 72GB or 96GB cards provide the capacity for larger models and longer context windows than a single card allows.
Registered ECC memory
System memory is registered ECC DDR5 across all four channels, suited to jobs that run for days. A common guideline is system memory at least equal to total VRAM; the configurator flags a selection below that.
Power and circuit requirements
Estimated draw at full load, and the circuit the system needs. The power supply is selected automatically.
| GPU configuration | Estimated draw | Power supply | Circuit |
|---|---|---|---|
| 1× RTX PRO 4500, 5000, or 6000 | 650W to 1,050W | 1600W | Standard 15A, 120V |
| 2× RTX PRO 4500 or 5000 | 850W to 1,050W | 1600W | Standard 15A, 120V |
| 2× RTX PRO 6000 | approximately 1,650W | 3000W | Dedicated 20A, 110–120V required; 30A, 220–240V recommended |
Assembly, burn-in, and delivery
Each system is assembled by hand at our shop in Fairport, NY, by a shop that has built computers for more than thirty years.
Fit and power validated
The configurator checks physical fit, memory, PCIe slots, and power on every selection. The power supply is sized automatically to the GPU count and estimated draw, with a 12V-2x6 cable for every GPU.
Burn-in under load
Every system is stress-tested under sustained full load and firmware-updated before it leaves the bench, so the first long job is not the first test.
Windows 11 Pro installed
Windows 11 Pro is installed and updated before shipment.
Warranty and support
Every build carries a 3-year warranty and lifetime technical support from the shop that built it.
Quoting and payment
The configurator shows a price for every part and an estimated total, including assembly, burn-in, and testing, as the build is configured. GPU and memory pricing changes frequently, so a technician confirms GPU availability and final pricing by email, with lead time, typically within 1-2 business days. There is no cost and no obligation to request a quote.
Payment for AI workstations is by ACH bank transfer; credit cards are not accepted for these systems. An invoice with bank details is issued once the quote is approved. Systems ship across the United States from Fairport, NY, with local pickup available.
