Buying Guide: What to Look For
- 1
**VA (Volt-Ampere) Rating:** Match the VA rating to your total power consumption. Add up the wattage of all devices you want to protect and multiply by 1.5-2 for a safe VA estimate.
- 2
**Runtime:** Consider how long you need devices to stay on. Higher VA and Watt ratings generally mean longer runtimes, but also higher cost and size.
- 3
**Sine Wave Type:** Pure sine wave is crucial for sensitive electronics like gaming PCs and devices with Active PFC power supplies. Modified sine wave is acceptable for less sensitive items.
- 4
**Outlets:** Look for a sufficient number of battery-backed outlets for critical devices and surge-only outlets for non-critical ones.
- 5
**Connectivity/Software:** Many UPS units include USB ports and software for automatic graceful shutdowns, which is highly recommended for computers.
- 6
**Form Factor:** Decide between tower, desktop, or rackmount designs based on your available space and aesthetic preferences.
Frequently Asked Questions
Q:How long will a UPS power my computer during an outage?
The runtime depends on the UPS's capacity (VA/Wattage) and the power draw of your connected devices. Most home office UPS units provide 5-15 minutes, enough time for a graceful shutdown, not extended use.
Q:Do I need a pure sine wave UPS?
If you have high-end PCs, gaming rigs, or devices with Active PFC power supplies, a pure sine wave UPS is strongly recommended to prevent potential damage and ensure stable power delivery. For basic electronics, a modified sine wave UPS is often sufficient.
Q:Can a UPS also protect against power surges?
Yes, nearly all modern UPS units include surge protection for all connected outlets, safeguarding your equipment from voltage spikes and lightning strikes, in addition to providing battery backup.
