BEFORE IT ARRIVES
Power, cooling & your space.
What this configuration needs on your premises.
Lab assessment · based on the evidence below
Office candidate
An office desktop candidate with published electrical limits. Apple’s wall-power test uses a larger configuration than this entry; measure your workload before budgeting a fleet.
Electrical input
Published detail100–240 V AC, 50–60 Hz, single phase; supplied AC power cord. [1]
Outlet & circuit
Not verifiedNo machine-specific branch-circuit requirement verified. Check the nameplate, regional cord and other loads on the same circuit.
Machine cooling
Published detailActive fan cooling. Apple requires a hard, stable surface with air circulation beneath and around the computer; keep ventilation openings clear. [3][4]
Operating limits
Published detail10–35°C operating ambient, 5–90% relative humidity, noncondensing. [1]
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.
M5 Ultra · 36-core CPU / 80-core GPU · 512 GB · 16 TB SSD
- Idle in vendor test
- 9 W
- Maximum in vendor test
- 385 W
Apple measured at the wall, including power-supply losses, at 20.2°C. Idle: Finder only. Maximum: compute-intensive processor workload. External peripherals excluded. This is a different configuration from this catalogue entry, not an LLM benchmark or a guarantee for your workload. [2]
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
- Confirm current M5 chassis specifications
- 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.
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 (4)
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.

Offline operationDoes the whole application work offline?
Local model inference is one part of the path. Test retrieval, documents, identity, tools and restart behavior as well.
