CyberPower CP1000PFCLCD UPS, 1000VA/600W, 120V, 10 Outlets, LCD Display, AVR, USB-A & USB-C, Black

This unit is fairly small so it will fit easily on a shelf or desktop near your PC. Keeping it off the floor will make the nice front panel display and controls much more useful as well as reducing the dust accumulation on/around the unit. Note that the cooling vents are on both sides of the unit (none on top), so you can't sandwich it between books on a bookshelf. The unit is completely silent when on AC power and emits only a slight buzz when running off the battery. Front panel display and controls allow you see/adjust nearly all of the features of this UPS, and Windows 7 automatically recognizes the unit (via included USB) and installs appropriate drivers so installing the included software is not really necessary. If you don't install the included software, auto-shutdown of the PC will be handled by the power management control panel within windows which now looks just like the one on laptop PCs, with separate settings for "plugged in" and "on battery". As advertised, this unit supports new desktop PCs using active PFC (Power Factor Correction) power supplies. I installed a new 750W active PFC power supply in my PC after the 10-yr old passive PFC supply began tripping hardware resets. With this new power supply, the computer would immediately shut down when I unplugged my old noisy APC square-wave UPS from the wall. This new CyberPower UPS sustains the system with no issues.

I've only had this 2 days. So far so good. Why ask me now? Ask me in 6 months.
