How to Choose

Pure Sine Wave Output

Modern gaming PC power supplies use Active PFC circuitry that expects a pure sine wave. Simulated sine wave can cause the PSU to draw excessive current, leading to random restarts or, over time, component stress. Always verify the UPS outputs pure sine wave if your PC was built in the last decade.

Wattage Capacity

Choose a UPS whose wattage rating exceeds your PC's peak draw by at least 20%. For a typical gaming rig with a 500W PSU, a 600W UPS might work, but a 900W unit gives headroom for monitors and peripherals. Use a power meter to check actual draw under load.

Battery-Backed Outlets

Not all outlets on a UPS provide battery backup; some are surge-only. At least four to six battery-backed outlets are needed for the PC, monitor, and router. Count your connected devices before buying to avoid adapters.

Automatic Voltage Regulation (AVR)

AVR corrects undervoltage and overvoltage without switching to battery, preserving battery life and runtime. It's especially useful in areas with brownouts or fluctuating mains power. Most reliable UPS models include this feature, but it's worth confirming.

Battery Runtime Under Gaming Load

Manufacturers often advertise runtime at a light 100W load, but a gaming PC drawing 300-500W will cut that to 5-15 minutes. That's enough to save your game and shut down, not to keep playing. If you need extended runtime, consider a larger battery or external battery pack.
