APC Back-UPS Pro 1200
Most power sockets; best readout
This APC is rated at 1200VA and features a 10-amp circuit breaker. You’ll find eight power connectors on the back – the most generous of the bunch – using the C13 sockets typically found on computing gear rather than standard power points. APC includes two power cables. Every socket offers surge protection to filter out power spikes, but only four sockets offer battery backup.
One of these battery backup sockets acts as a master, controlling the second battery backup socket along with three of the surge-protected sockets. When the master device (presumably your computer) is shut down, the UPS cuts the power to the slave devices. You’ll also find telephone and Ethernet jacks on the back to filter out spikes on your phone line and data cables.
The APC’s front screen offers five-bar readouts for the battery charge level and the power load from the attached devices. Below this is an option button that lets you toggle through the input and output voltages, power frequency, the remaining time, the watts used by attached devices, the power load percentage and the remaining battery time. You can connect this UPS to your computer via USB although APC doesn’t supply a Mac version of its PowerChute management software. The UPS does show up under the Energy Saver System Preferences on your Mac.
The UPS features a very quiet fan, but it ramps up when the power is cut. It emits four quick beeps every 30 seconds, with a rapid beep when there’s less than 60 seconds of charge left. Thankfully there’s a mute button.
Tested with a quad-core Mac Pro hooked up to a 24in Dell monitor, using 210 watts, the APC ran for 18 minutes and 50 seconds – offering an efficiency of 0.94 seconds per VA.
Plenty of sockets and a detailed readout make the APC a handy addition to a busy workspace.
