BUYING GUIDE
Pure Sine Wave vs Simulated
Always buy pure sine wave for home lab equipment. Simulated sine wave UPS units can damage active PFC power supplies found in servers and NAS devices. The CyberPower PFC series and APC Smart-UPS line are all pure sine wave.

A great example of this in practice — check current price on Amazon.
Sizing Your UPS
Add up the wattage of everything you want to protect. A typical home lab with 2-3 mini PCs, a switch, and a NAS draws 150-300W. Buy a UPS rated for at least 2x your load to get reasonable runtime and battery longevity.
