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
An office installation needs a planned circuit and enough cooling for long-running workloads. Dell explicitly requires a 20 A circuit.
Electrical input
Published detail1,600 W rating: 115–240 V AC. Maximum input: 16 A at 115 V or 8 A at 240 V. Input frequency range: 47–63 Hz. [1]
Outlet & circuit
Published detail20 A circuit required by Dell. Use the original power cable directly at the wall; Dell recommends isolating the computer from other devices. Confirm the regional installation with facilities. [1]
Machine cooling
Published detailMaxCool liquid-cooling assembly with a cold plate, two heat exchangers and redundant pumps. [2]
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
- Confirm selected configuration
- Weight
- Not verified
- 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 Dell to confirm the final cord, cooling service procedure and whole-system ambient limits for the ordered configuration.
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.

Customer deploymentField record
Accounting & advisory firmAn 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.

Large enterprises · several sectorsA coding agent for every engineer, without an exploding token bill.
GB300-class workstations serve local open-weight models for most of the work; frontier cloud models are called only for the tasks that need them. Engineers work in VS Code with a local harness and a specification assistant.
