Use measured watts for the next decision
The calculator is a planning estimate. Power-supply labels show maximum capacity, not the electricity a device normally draws. Measure the complete setup at the wall for at least a normal workday before buying replacement hardware or backup power.
Record idle draw, a typical workload, and a short peak such as a NAS scrub or system startup. Use the sustained figure for electricity cost and the higher observed figure when sizing a UPS. Leave capacity for the router, switch, storage, and any equipment that must remain online together.
If the measured load is already low, replacing working hardware may cost more than the electricity it saves. If idle draw is high, compare consolidation and efficient mini PCs first. For outage protection, use the measured watts in the UPS and router-runtime guides.
