In the last year there have been several power outages ranging from several hours to transient outages of a few seconds.This is where an external uninterruptable power supply (UPS ) comes in handy.
A UPS is like a big battery that gets charged from main power, but when there is an outage the battery kicks in and provides power to connected devices. Having researched typical power consumptions and armed with the knowledge that my PC uses SSDs, is fan-less, and does not have a high-powered GPU something in the 1000-1500 VA range was required. My main requirement was the ability to save work and safely shut down the PC before losing all power. If I had more complex energy requirements I would have first purchased a power meter to measure how much power my devices were using before choosing the UPS. For example the main group can have the PC and one of the monitors connected. The secondary power group can have non-essential devices attached, in my case the powered studio monitor speakers. The UPS was configured to turn off the secondary group if there is a power outage but after a 15 second delay; this will help with short transient outages. The main group will remain on for as long as the UPC battery has power. There are many different ways to configure this UPS by using the LCD display and front buttons, including the ability to enabledisable audible notifications. Once the UPS battery is fully charged, turning off the main power at the power outlet causes the UPS to switch to battery power, the PC and single monitor stay on and 15 seconds later the speakers turn off (to save power). Once on battery, the PC and monitor draw about 50W of power and the estimated run time according to the UPS LCD is about 2 hours. If however the PC is unattended at the time, I still want it to be safely shutdown. From here, Additional power settings can be opened and power plans customized. Once in the plan settings, the Change advanced power settings can be selected to get down into the fine details. I also modified some o the other battery settings.
