A vendor-neutral planner for sizing data-center power, cooling, UPS capacity, and rack circuits.

Landing page captured for the 2026-08-30 issue.

Field notes

The calculator combines rack or device-level IT inputs with power factor, PUE, receptacle, UPS, circuit, and environmental settings. Its output separates facility power, apparent power, UPS capacity, cooling demand, and circuit loading rather than collapsing them into one estimate. The visible example uses 60 kW of IT load, produces 204,729 BTU/hr of heat rejection, and selects two circuits per rack to remain under the stated 80% continuous-load threshold.
