The Ultimate Buyer’s Guide: How to Choose The Right Product for You

Key Factors to Consider

• Capacity (VA and Watts): This is the most important factor. Calculate the total wattage of the devices you want to protect (your PC, monitor, router, etc.) and choose a UPS with a watt rating that is at least 20-25% higher to give you a safe margin. VA (Volt-Amperes) is another rating, but wattage is the more critical number for modern electronics.
• Runtime: How long do you need the battery to last? If you just need enough time to save your work and shut down (5-10 minutes), most budget models will suffice. If you need to keep a router or server running for an hour or more, you’ll need a larger capacity unit or one with an external battery pack option.
• Number and Type of Outlets: Count how many devices you need to plug in. Ensure the UPS has enough outlets that are both battery-backed and surge-protected. Also, check the spacing, as bulky power adapters can easily block adjacent outlets.
• Form Factor: UPS units come in various shapes and sizes. Tower models are common for placing on the floor, while flatter, power-strip-style units can be more convenient for placing on or under a desk.

Understanding Sine Wave vs. Simulated Sine Wave

This is a technical but crucial difference. The electricity from your wall outlet is a smooth, consistent wave called a “true sine wave.”

• True Sine Wave: Higher-end UPS models, like our top pick, the CyberPower CP1500PFCLCD, produce a true sine wave output when on battery power. This is the cleanest power and is essential for sensitive electronics, especially modern computer power supplies that use Active Power Factor Correction (Active PFC). Using a non-sine wave UPS with these devices can cause them to shut down unexpectedly or even suffer damage.
• Simulated Sine Wave: More affordable UPS units use a “simulated” or “stepped” sine wave. This is a choppier approximation of a true sine wave. For the vast majority of electronics—like routers, TVs, game consoles, and computers with older or less sensitive power supplies—this is perfectly adequate. However, it’s best to avoid using them for high-end PCs or delicate audio equipment.

Common Mistakes to Avoid

• Plugging in a Laser Printer: Never plug a laser printer into the battery-backed outlets of a consumer-grade UPS. The high power draw when the fuser heats up can instantly overload the UPS. Use the surge-only outlets for these devices.
• Ignoring the Wattage Rating: Don’t just look at the big VA number on the box. The wattage rating is the true measure of the UPS’s power capacity. Ensure your total device load does not exceed this number.
• Forgetting to Test: Once you’ve set up your new UPS, perform a simple test. With your computer on, unplug the UPS from the wall. Your computer should stay on without a flicker. This confirms everything is working correctly before a real outage occurs.
• Expecting Infinite Runtime: A UPS is a temporary power source. Its job is to give you time to shut down gracefully or to bridge a very short power gap. It is not a generator designed to run your office for hours on end (unless you invest in a model with external battery packs).

Frequently Asked Questions

What is a reasonable price for a good entry-level UPS?

A reasonable price for a good, entry-level UPS for a basic desktop computer or networking equipment typically falls between $70 and $150. In this range, you can expect to find units with adequate capacity (around 600VA to 900VA), several battery-backed outlets, and essential features like surge protection.

What features do you typically give up with a budget UPS?

With a budget UPS, you often give up a “true sine wave” output in favor of a “simulated sine wave,” which may not be ideal for sensitive electronics with Active PFC power supplies. You may also get shorter runtimes, fewer outlets, a lack of an LCD information screen (relying on simple LED indicators instead), and fewer premium features like USB charging ports or energy-saving modes.

Are cheap uninterruptible power supplies reliable?

Yes, many affordable UPS units from reputable brands like APC and CyberPower are very reliable for their intended purpose. They are excellent at protecting against common power problems like short outages, sags, and surges. Reliability issues are more likely to stem from overloading the unit or the natural degradation of the internal battery over its 3-5 year lifespan.

How can I find the best value UPS for under $100?

To find the best value under $100, focus on the wattage capacity and the number of battery-backed outlets. Look for a model from a well-known brand that offers a wattage rating at least 25% higher than the total power draw of your essential devices. Often, you can find great deals on slightly older models that still provide excellent protection without the latest features.

Is a budget UPS sufficient for a basic desktop computer?

Absolutely. A budget UPS is perfectly sufficient for a basic desktop computer, monitor, and router. Its primary job is to provide enough power for you to save your work and perform a safe shutdown during a power outage, which prevents data loss and protects your hardware from an abrupt power cut. Most budget models provide 5-15 minutes of runtime for such a setup, which is ample time.

Do budget UPS systems offer surge protection?

Yes, virtually all budget UPS systems include surge protection. They typically feature two types of outlets: some that offer both battery backup and surge protection, and others that provide surge protection only. This allows you to protect critical equipment (like your PC) from both outages and power spikes, while also protecting less critical peripherals (like a printer) from surges.

What is the cheapest way to get battery backup for my router?

The cheapest way to get battery backup for just a router is to purchase a small, lower-capacity UPS (e.g., 450VA to 600VA). Since a router consumes very little power (typically 5-20 watts), even a small UPS will provide a very long runtime, often an hour or more, keeping your internet active during an outage.
