BEFORE IT ARRIVES
Power, cooling & your space.
What this configuration needs on your premises.
Lab assessment · based on the evidence below
Office with facilities review
Request an installation plan with the final Exxact quote. This GB300 configuration needs OEM-specific electrical and cooling confirmation before office deployment.
Electrical input
Not verifiedRegional input voltage, current and connector are not verified. Check the supplied power unit and installation manual.
Outlet & circuit
Published detailNVIDIA specifies a 20 A circuit for the DGX Station platform. Have the supplier confirm the exact OEM system, input voltage and regional connection requirements. [2]
Machine cooling
Not verifiedThe exact cooling assembly is not documented in the reviewed source. Request the thermal and installation specification.
Operating limits
Not verifiedWhole-system ambient temperature and humidity limits are not verified. A power-supply temperature limit is not a system limit.
Noise in the workspace
Not verifiedNo 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.
Idle and AI-load wall power: not verified.
Share a power measurement No attributable wall-power test for this configuration was established in this review. Measure at the outlet with the exact model, workload, runtime and power mode recorded.
Room cooling
Allow for sustained room heat, including after office hours. A ventilated equipment room may be more practical for multiple systems or continuous jobs. An internal liquid cooler does not remove the need for room cooling.
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
- Not published in source extract
- Weight
- Not published in source extract
- 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.
- Ask Exxact to identify the chassis, PSU input, regional cord, cooling loop, ambient limits, loaded weight and workload acoustics in the quote.
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 (2)
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.

BEFORE YOU CHOOSE
One of the few GB300 workstations with a public starting price. The starting configuration excludes drives, the optional display GPU and support options; the configurator sets the final price.
Same GB300 superchip, memory and networking as every DGX Station; the chassis, cooling and warranty are Exxact’s.
Supports one double-wide graphics card for display alongside the GB300.
