Battery Backup Test Results
While the Cyber Power CP825AVRLCD and CP1000AVRLCD UPS's are added for comparison, all of the other battery backup UPS devices are all rated for 1500VA. APC's premium-priced BR1500LCD model comes equipped with an LCD readout, although it provides only 865 watts at 1500VA. The Powercom Black Knight Pro BNT-1500AP is one of the most affordable products in the 1500VA segment, but this model doesn't offer any equipment guarantee or LCD diagnostic display like CyberPower does on their CP1500AVRLCD, and the warranty is a short-lived two years. Tripp Lite's OMNIVS1500 is a no frills UPS that offers a manufacturer-specified 940W but lacks any comprehensive status feedback or LCD display. The Tripp Lite SMART1500LCD provides basic feedback on a small LCD screen, and offers both rack or floor mount hardware, but also comes with a hefty price tag.
Home Theater System (510W - Extreme Load)
Home theater power demands will differ depending on the equipment used, and the task at hand. For our extreme load test we reproduced a higher-end entertainment center with all of the deviced powered on. HDTV's fluctuate their power demands based on the displayed content and screen temperature (blank screens draw very little power, while colorful motion draws the most), and our 52" HDTV consumed approximately 340 watts cold before warming up to 190W operational. The Sony PlayStation-3 gaming console serves a dual-purpose as a Blu-ray Disc player, and consumes up to 140W either way. Surprisingly, the A/V receiver required less power than anticipated, asking for only 80W on average with five large speakers attached at normal volume. The remaining power was drawn from a combination of satillite tuner/DVR and universal remote control.
High-Performance PC (360W - Heavy Load)
Computer hardware enthusiasts need consistent power for their high-performance computers systems as much as anyone, but they're more likely to require higher volts-amp power for their system than the electricity demands of similarly purposed devices. For our high-performance computer run-time tests, Benchmark Reviews used only the most powerful hardware for our computer system. A dual-GPU Radeon HD5970 powers high-end graphics and a 26-inch LCD monitor, while an overclocked quad-core processor and system memory keep the system running quickly. While not charted, we experimented with the CyberPower CP1000AVRLCD just to see what kind of on-battery run time we could reach, and learned that volt-amps is everything when the UPS lasted only six minutes.
Workstation PC (200W - Medium Load)
More in-line with what small-office and casual home users will require, the 200W workstation computer uses many of the latest performance-orientated parts but stops short of the obscene enthusiast hardware components used in our heavy load test. While we've labeled this as a 'medium load', the power demand is very much only relative to our other tests. As a result, this test includes the CyberPower 825 and 1000VA models for testing against the more powerful 1500VA versions. One lesson learned from this test is that UPS battery backup devices with high volts-amp rating will sustain a much longer run time thanks to a reduced relative load percentage, which we detail below.
After recording all of our test results, it was clear that CyberPower Systems offers consumers superior on-battery run time with their CyberPower CP1500AVRLCD UPS. My memory of our tests using the CyberPower CP1350AVRLCD a few years back reminded me of a similar outcome, which ranked the 1350VA/810W above some of the competing 1500VA/900W battery backup solutions. While the CyberPower CP1500AVRLCD didn't outclass each and every other UPS, it certainly proved to outperform the competition.
Our tests on the less-powerful CyberPower CP825AVRLCD and CP1000AVRLCD UPS devices proved that they'll sustain a decent on-battery run time when the power goes out, but unless the outage is somewhat momentary it would be best to assign them to lightweight power applications such as basic computer systems and small electronic devices. While some users might appreciate the opportunity to save their work and power down the computer system, many of the visitors who frequent Benchmark Reviews would prefer to keep working through the storm and finish their download or get every last frag with their games.
This leads into a related point worth making: don't overload your UPS battery backup with unnecessary devices. It's important to avoid placing lamps, printers, and personal space heaters on the battery-backup side of any UPS, and relegate them to surge-only support. The average laser printer or 100W light bulb could consume as much power as the computer system does, and heaters will dramatically reduce battery run time. Monitors add nearly as much load as the average PC tower, but most users can't get by without one.
