I bought it without doing too much research. It is very well built with a solid durable plastic front face and aluminium frame with steel casing.
420VA puts it in as an entry level unit but in reality this is more than enough to provide first class protection and a clean shutdown. I have mine connected to two IPS flatron led monitors and the PC is a custom built I5 overclocked with two HDD 1TB drives, 16GB ram, Windows 7 64bit. In testing this UPS was able to run my modern machine for a good 35 minutes idle and Powerchute reported a 25% load.
My two bugbears is this UPS is lacking a USB interface and the documentation leaves you in the dark if trying to achieve a minimal installation.
Step 1 (lack of USB)
My PC is bursting with USB 3.0 and 2.0 ports on the front and rear with no RS323 serial. I didnt want to fit a dedicated internal serial card so to solve this I bought:
StarTech 1 Port FTDI USB to Serial RS232 Adapter Cable with COM Retention...
Windows 7 auto detected the new port no problem and it seems its important to buy a quality adapter that is using the FTDI chipset.
Step 2 Software
By trial and error the only software necessary to install is "PowerChute Business Edition AGENT" which detected the unit no problem. You then simply visit [...] in a web browser to view usage reports and make any configuration changes. I discovered the APC network server and other packages on the CD are not necessary. I also discovered this APC Smart-UPS SC will not work with PowerChute PE (Personal Edition) as PE only supports APC units that have direct USB. I've also tried [...] but gave up trying to configure the package. PowerChute Business Edition Agent just works straight out the box with minimal system resources.
