BEFORE IT ARRIVES

Power, cooling & your space.

What this configuration needs on your premises.

Requirements reviewed 2026-09-29
Lab assessment · based on the evidence below

Office candidate

A compact office candidate. Its documented operating ceiling is 30°C: an unventilated cupboard or warm equipment shelf needs particular attention.

Power rating

Published detail

240 W external adapter capacity; 140 W SoC TDP. Neither number is typical wall consumption. [1]

Electrical input

Published detail

48 V DC, 5 A at the computer. Use the approved adapter and grounded power cord; check its AC input label for your region. [2]

Outlet & circuit

Not verified

No machine-specific branch-circuit requirement verified. Check the nameplate, regional cord and other loads on the same circuit.

Machine cooling

Published detail

Air-cooled heatsink and two fans, documented in ChargerLAB’s disassembly of the 4 TB model. Heat pipes also serve supporting components. [3]

Operating limits

Published detail

5–30°C operating ambient. Keep the system and adapter ventilated. [2]

Noise in the workspace

Not verified

No comparable noise measurement under an AI workload verified. Ask for dB(A), distance, workload and ambient conditions; audition it before placing it beside people.

ACTUAL CONSUMPTION

Power at the wall

PSU capacity, chip TDP and measured consumption describe different things. Only measurements with a stated configuration and test method appear here.

Manufacturer test · this model

NVIDIA DGX Spark · regulatory model P4242

Idle in vendor test
38 W
Maximum in vendor test
233.2 W

NVIDIA compliance measurements under IEC/EN 62623 at 230 V, 50 Hz. These are vendor test points, not measurements of an LLM workload or of another GB10 manufacturer’s box. [2]

Share a power measurement

Room cooling

Plan for the computer and its power supply to heat the room. Check ventilation during long jobs and when several machines share a small office.

Lab planning guidance. Office suitability depends on the installed configuration, shared circuits, heat removal and acceptable noise; a workstation label alone does not settle it.

Space & installation

Enclosure
150 × 150 × 50.5 mm
Weight
1.2 kg
  • Keep air inlets and exhausts unobstructed, with room for cables and servicing. An enclosed cupboard needs its own ventilation; the enclosure dimensions are not an airflow clearance.
Estimate electricity use & room heat

Enter average power at the wall for the hours you are modeling, or an explicit planning assumption. Supply wattage and chip TDP are not consumption measurements.

Add wall power to calculate a scenario.

Scenario only. Hours outside this period are excluded: include idle time for an always-on system. Displays, networking, UPS losses and room air conditioning are extra. Heat assumes the computer and power supply release their heat into this room; it does not size a circuit or an HVAC system. Currency selects your tariff’s unit, with no conversion.

Sources & review scope (3)

Manufacturer documentation and attributed first-hand hardware inspections, scoped to the named model or configuration. “Not verified” identifies a gap in this review, not a claim that the manufacturer has no documentation. Installation assessments are the Lab’s interpretation.

01 / PRIVACY

Your data has a home.

Keep sensitive processing on your infrastructure. Inspect every connection in the complete stack.

02 / SECURITY

You set the boundaries.

Control access, connectivity and updates. A local machine still needs a secure deployment.

03 / TOKEN ECONOMICS

Own the capacity.

Generate tokens on your own compute. Understand the full cost of the useful work it delivers.

DEPLOYMENT NOTEBOOK / NVIDIA GB10

From a desktop box to a managed service

01

Arm software compatibility

Check that every container and native dependency supports arm64. Model compatibility alone does not validate the application.

02

Shared-service operations

NVIDIA now documents fleet lifecycle integration and customized installation. Its example tools need adaptation to your IT environment; they are not preinstalled.

03

A meaningful capacity test

Record prompt length, output length, cache state and simultaneous requests. Repeat after warmup and report the latency target and failure rate.

IN THE FIELD

Deployment experiences

Operating records from customers, contributors and the Lab.

All deployments
Customer deploymentField record
Semiconductor company · Wi-Fi products

A GB10 beside every test bench: autonomous execution, retest and insight in a Wi-Fi NPI lab.

Two agents run the lab’s existing Python test automation through the controller API, judge results against the formal pass/fail protocols, retest within protocol and report. After a three-month pilot, each test bench received its own GB10-class workstation.

Accounting & advisory firm

An accounting and advisory firm runs its legal document automation on premises.

A GB300-class appliance in production and a GB10-class appliance for development, installed at the firm, run the Understand Tech platform locally. The first application automates legal documents; the firm holds its source code.

Rare-disease diagnosis support from dental photographs and radiographs, planned on an on-site appliance.

A six-month pilot of a vision-plus-retrieval pipeline that turns intra-oral images into standardised phenotypes and weighted, source-cited rare-disease hypotheses. Production is designed for a DGX Spark-class appliance on site, air-gap capable, for health-data sovereignty.
