[QUOTE="westom, post: 1408909, member: 138367"] Printer has a relevant number where the power cord connects. That would be its power supply (or power brick). It is probably rated at 70 watts. The Mac would also have specifications elsewhere such as on paper specs. Typically about 200 watts. Maybe the display is another 40 watts. Adding these numbers, 260 + 70 + 200 + 40 means the UPS must provide a maximum 570 watts. A UPS is typically made as cheap as possible. Batteries degrade typically in three years. Therefore we probably want 800 watts for that and other reasons. Then as its battery is seriously degraded, it can still provide sufficient power three years later. Usually most do not power the printer on a UPS since the UPS does not need the temporary and dirty power during a blackout. Your system will not consume 570 watts. That is just a worse case number to guarantee human safety requirements. [/QUOTE]
