CyberPower CP1500PFCLCD 1500VA Pure Sine Wave-Cures MacPro Wake From Sleep Shutdown
Purchased this CyberPower unit about month ago. Have 2008 MacPro 8 core 3. GHZ fully loaded internally that was running for last couple years along with assorted Monitors-(2), printer etc. Had been using an APC 1500 & APC 1000- splitting various thing around plugged in to either one to share load. A MDD dual processor was in the mix but it was always on the opposite power supply, not both on one APC unit. For the last 3 yrs have been enduring endless stupidity with these APC power supplies. They would shut down randomly & repeatedly EVEN if the MacPro was not the one on that particular power UPS.Although for the most part - the UPS that was on the MacPro would shut down. You could switch a light on in another room- even a 1 bulb 75 watt could essentially trigger one of the 2 APC units to shut down as if they were overloaded. They were not. House is newer & wired correctly with 12 gauge/20 amp romex wire everywhere for any normal 110v outlets & 8 gauge 50 amp for 220v outlets & 200 amp service. The 2 power supplies are on their own line by themselves-nothing else. I am very familiar with house wiring & have rewired several homes I've owned. All wiring in house is up to snuff done properly. I tolerated this nonsense with these APC for years. They made absolutely no sense. I was aware at some point & positively as of recent reading that the 2008 MacPro's had PFC power supplies in them & that they would prefer pure sine wave power- as house current is. Even with that knowledge it still made no senses as to the random-regular weekly shutdown on the APC units with the computer asleep not even trying to wake or even having A TRUE power outage. The batteries checked out ALWAYS and if not hooked up to computer would work fine. If computer was awake & cut power they would hold system for as many minutes long as they were expected to. No problem. Just if asleep- turn light on anywhere in house- units sometimes/randomly cut out. If house current off & wake computers units shut down. Stupid really. Whats the point of the power supply ? (sounds like I am reviewing the APC's not CyberPower-right ?)Finally my MP had 8Gb of ram out of 16GB go bad. Had it replaced and I said that's it. I mean really- the APC power supplies were shutting down on a almost weekly basis & there wasn't even any power failures- the units themselves were THE power failures. Did as much research as possible regarding PFC power supplies & chose the CyberPower PFC 1500 unit. Cost more than the similar NON pure sine wave APC units. But cost quite a bit less than the Pure sine wave APC units. Who knows why APC charges so much for pure sine wave units. But after using their product probably for nearly 15 yrs- I was done. The CyberPower unit is a GREAT unit. Have read various reviews about the power switch(on unit-on/off & menu) etc problem some are having with it-I don't get the problem. It is a bit of a different technique how the button operates- but I picked it up quickly. The current power draw in numbers of watts as well as load capacity being used on the LCD display is great. You have real-time readout if you chose to, as to those numbers. It's like having Kill-A-Watt meter always on. You get to see the basic power fluctuations of your components. The unit is very compact- somewhat smaller than the APC 1500/1000 units. Right now connected with MacPro w/4 Hitachi 7200 rpm 64MB cache 3TB drives internal, ATI/Apple 5870 video card- w/3 24" monitors, epson 3800 printer, external OWC QX2 raid case w-4 hitachi 7200 rpm 32 MB cache 2TB drives & 2008 8 core MacPro booted off of that raid case along with MBP early 2011-17" plugged in but asleep, DSL modem, Dlink 8 port gigabit ethernet hub, 5th Gen AirPort extreme, MDD G/4 plugged in but off, the CyberPower shows a load of about 564 watts. That draw is confirmed accurate(slightly less actually for CyberPower unit itself not being in mix) if all were disconnected from CyberPower unit and plugged in- instead to the Kill-A=Watt meter. Everything asleep around 54 watts draw. I can switch ANY combination of light/appliance/central a/c /55" plasma/electric 220v clothes dryer/3.5HP 220v air compressor/ 5500watt electric heater- 500 gallon spa w/dual pumps etc in any combination on or off with computers asleep, awake, getting awake, going to sleep. UPS functions PERFECTLY & as expected- stellar performance. NO random shutdowns-nothing. Cut power to unit while computers asleep-no problem. You know the conclusion here -right? Pro's * Economical, compact, nice looking * PFC compatible- Pure Sine Wave unit. * Operates flawlessly * Cheaper than APC pure sine wave units * Power consumption/load LCD is very useful if you like that sort of thing-I do * 3yr warranty -same as APC Cons * Cost more than NON PFC compatible/Pure Sine Wave units * CyberPower warranty/service- unknown quality yet. APC was/had excellent service Conclusion. Highly recommended, especially if you have any of the MacPro's. I imagine some on PC side have units that are PFC and would require pure sine wave to operate a UPS on those computers properly also. I will not ever buy a UPS that is not a pure sine wave unit again. Read more
