For computers and UPS units, watt and VA ratings can differ significantly, although VA rating is always equal to are larger than watt rating. When sizing a UPS for your specific requirements, the power factor matters most. That depends on what you intend to backup with your UPS.
Runtime refers to the amount of time a UPS will be able to power its attached equipment in the event of a power disruption. What are some key features to understand when choosing a UPS system? Basic User-Replaceable Batteries - Increases availability by allowing trained users to perform battery upgrades and replacements. Surge-Only Outlets - Protect secondary electronics from surges and spikes without reducing battery power used to run primary electronics during outages.
Building Wiring Fault Indicator - LED indicator that informs users of potentially dangerous wiring problems in wall circuits. Transformer-Block Spaced Outlets - Protect equipment without blocking access to other receptacles. Automatic Self-Test - Periodic battery check that ensures early detection of batteries needing replacement. Enhanced Automatic Voltage Regulation AVR - Gives high application availability by correcting low and high voltage conditions without using the battery.
Pure Sine-Wave Output on Battery - Simulates utility power to provide the highest degree of compatibility for active PFC power factor corrected servers and sensitive electronics.
Scalable Runtime - Allows additional runtime as needed via external battery packs. Power Conditioning - Protects connected loads from surges, spikes, lightning, and other power disturbances. A simple way to think about the utility of a UPS unit is to think about working on a laptop. A summer storm knocks the power out. Although the lights go out, your work on the notebook computer is uninterrupted because the notebook switched over to battery power seamlessly when the flow of electricity from the power cord vanished.
You now have plenty of time to save your work and gracefully shut down your machine. If you had been working on a desktop during that power outage, the system would come to an immediate halt. Not only would you lose your work, but the process imposes unnecessary stress on your machine. In all our years of working with computers, the vast majority of hardware failures can be directly attributed to the stress hardware components experience during the shut down and startup process especially if power surges or blackouts are involved.
A UPS unit would, at minimum even with a very small unit, provide a window of time where your computer could be gracefully shut down or sent into hibernation mode and brought back online once the power outage or other power situation was resolved. If the situation is resolved while the UPS unit still has enough battery life remaining, then you can work right through the storm without interruption.
The UPS market is a very diverse one. You can find tiny desktop units designed to keep a lightweight desktop computer running for 10 minutes, or walk-in-freezer sized units deployed in data centers to keep an entire bank of servers running through a storm. The most important step in your UPS selection and shopping process is to sit down and chart out your power needs before spending your hard earned cash on gear that is overkill or worse, underpowered for your situation.
First, think about all the systems in your home or office that need the extended power protection supplied by a UPS unit, to stay online in the event of power outages, or both.
The most obvious system would be your desktop computer. Less obvious, but still important, are any secondary computer systems such as a home media server or network attached storage device used for local backup. In addition to the primary computers and auxiliary computers, are there other electronic devices that you want to protect from power outages and keep online?
In our case we also have a cable modem, router, and Wi-Fi node that we would like to protect from power loss. At the bare minimum, you need enough juice in your UPS unit to give your computer system adequate time to shut down properly.
So how can you calculate the power needs of the system? The first step is examining the core system and peripherals you wish to keep on in the event of power loss. On the other hand, our two computers in the home office and the playroom do have peripherals like monitors, external hard drives, and so on.
If you want to be extremely precise with your calculations, you can use a power meter to measure the actual consumption patterns of your devices. Alternatively, you can look at the power supply rating for your computer as a measure of the maximum power the computer will pull. Our home server has a w power supply, but when measured with a Kill-a-Watt measuring tool, it has a peak startup load of a little over w and a consistent operating load of only around w.
Alternatively, you can increase the precision of your calculations by using a measuring device and allocate more of your budget toward UPS unit features you want and less toward buying a bigger battery.
Volt-Amperes are the standard measurement used to describe the capacity of UPS units. So how long will that minimum system run the setup?
There are three principle UPS design types available. A Standby UPS unit charges its battery and then waits for the mains power to drop off. When that happens, the Standby UPS mechanically switches to the battery backup. This switch over takes about milliseconds, which is generally well within the tolerance threshold of most electronics. This special transformer makes Line-Interactive UPS units better at handling brownouts and power sags. If you live in area that has frequent brownouts or line-voltage issues e.
The Online UPS unit completely isolates the devices attached to it from the wall power. Instead of jumping into action at the first sign of power out or voltage regulation issues like the Standby and Line-Interactive units, the Online UPS unit continuously filters the wall power through the battery system.
Because the attached electronics run completely off the battery bank which is being perpetually topped off by the external power supply , there is never a single millisecond of power interruption when there is power loss or voltage regulation issues. The Online UPS unit, then, is effectively an electronic firewall between your devices and the outside world, scrubbing and stabilizing all the electricity your devices are ever exposed to. Even though a UPS unit is effectively just a sophisticated battery, there are tons of little features that can greatly enhance your UPS experience.
Any UPS unit worth the money will include some method for interfacing with the computer it is attached to. But as is the case with all other products on our best UPS for a gaming PC list, the outlets are evenly split between battery backup and surge protection. The model includes automatic voltage regulation, guaranteeing stable input voltage without using up battery power. The company does not only specialize in UPS production but also manufactures networking equipment, cables and other products.
It weighs around 12kg, and the product dimensions are 49cm x 23cm x 28cm. The UPS has 10 outlets split between those that provide only surge protection and those with battery backup.
Data lines are largely unprotected and can facilitate power surges that damage your devices. This UPS comes with pure sine wave technology while you have power. But it switches to a simulated sine wave when the backup battery comes on.
At maximum power, users have over 2 minutes to properly shut down all processes. Keep in mind that most devices rarely operate at maximum power, giving users additional time to turn off their devices. Therefore, if you are looking to save money and get the best large UPS for a gaming PC of and , this is the one for you. UPS is basically a security system for your computer: it protects your PC from power outages and fluctuations that can damage your device.
UPS is sometimes confused with battery backup. However, the latter only refers to devices that provide emergency backup power and not protection from power fluctuations. UPS systems can be broken down into two categories when looking at output waveform. Meanwhile, a simulated stepped sine wave produces a less stable and choppier output. But some devices tend to be sensitive to these simulated waves which can result in complications. Our reviews take the output waveform into account and examine its effects on other UPS features.
The best large UPS for a gaming PC must have enough juice to keep your gaming rig running long enough for you to save everything and shut it down safely. Therefore, we looked at the power capacity of each reviewed UPS model, which is measured using the volt-ampere power output rating. Dimensions and weight are important aspects to consider when choosing a UPS.
We also kept a close eye on the number of outlets on each reviewed UPS because this determines the number of devices that can be hooked on. Meanwhile, the presence of an LCD screen gives you access to customization options and allows you to track the amount of pressure being placed on the UPS device.
The price is a crucial factor in the purchasing decision. In our review of the best inexpensive UPS for a gaming PC, we compared the prices of different models on the market and what you are actually getting for your money. Depending on how much you want to spend, a power surge protector may prove a more affordable option. However, UPS is definitely a worthwhile investment because you never know when a sudden loss or fluctuation of power might happen.
The capacity of the UPS should be based on the amount of power your PC needs and the additional equipment plugged into it.
While Cyberpower might have a slightly better reputation, both companies produce top-of-the-line products. The final decision boils down to personal preference and individual models. It depends on the power capacity of a specific UPS. We included runtime calculations for each model on our best UPS for a gaming PC list, allowing you to see how long your machine can run during a power outage.
