CyberPower Professional PP1500SWT2 1500VA 1000W 7 Outlets UPS

Pros: I have not had one problem with this unit thus far and I've had it for 8 months now. This is a true sine wave unit, where if you are using a power supply with Active PFC, this is what you want. With cheaper "simulated sine wave" UPS units, you'll hear a loud hum from your PC's power supply if it uses Active PFC when a simulated sine wave UPS is on battery power, as the PFC circuitry is working extra hard in order to clean up the harmonics in the "simulated sine wave". As the "simulated sine wave" is just a modified square wave, the harmonics are typically high, depending on the unit. I had first bought one of the cheaper units and found this out from experience, and after looking around I liked the specs on this unit and decided to purchase it. I am definitely happy with it and it has in fact kept my PC running flawlessly when the power dipped one afternoon.

Cons: None.

Overall Review: The unit is silent and can power my PC for over half an hour on battery. My P: E6850 Intel Core 2 Duo overclocked to 3.6 Ghz, factory overclocked XFX 8800GT video card, 2GB Crucial Ballistix, Scythe fan controller running two front fans, one rear fan, and the video card fan, Ninja CPU cooler, a WD 320 GB system disk and 3 WD 500 GB disks configured in RAID 5, a Samsung DVD writer, and a NEC 24 inch monitor. The power level as displayed by CyberPower's PowerPanel Plus software is only at about 20% at most, and shows it can run the PC for over half an hour on battery.

Pros: Florida here -so I realy, realy need good reliable UPS. Just 3 words -Pure Sine Wave! Good price to VA ratio.

Cons: None so far

Pros: Durable build and nice case.

Cons: If you approach top load pushing about 600 watts the fan kicks on full speed and is very, very noisy. It could not power my system and stay quiet so I now have it powering by HDTV, DVD and DVR (something that is quiet useful in New Orleans with our power outages).

Overall Review: Software that comes with it does not work in Vista -- download the other software for the WT4 version and this works. Jeff in tech support was very helpful and told me about this.

Pros: Best UPS money can buy for home/soho environment. I researched a lot before purchasing. As I had read about most newer PC Power Supplies being Active. Ant that there is some incompatibility between the lower priced UPS's and Active PC Power Supplies. I emailed CyberPower Technical Support and got a response withing 24 hours. Here's what they had to say: 'Yes, there can be PSU incompatibility with UPSs. Power from the utility company is pure sine wave. When utility power is normal, the UPS will pass through the pure sine wave to your equipment. When utility power is cut and the UPS begins running on battery power through an inverter, the output is a simulated sine wave, not a pure sine wave. Simulated sine wave is more like a stairway...straight across, then straight up, etc... This type of power output will work fine with most electronics and most PSUs. However, recently, more and more PSUs are Active PFC. Active PFC PSUs are more efficiently designed and they require a...

Cons: CyberPower response continued: '...more specific kind of power. They work fine on utility power or a pure sine wave UPS power, but when they receive simulated sine wave power from a UPS, they can often reject the power, and the PSU will either shut off and not work completely, or cause the computer to reboot. So, if your power supply is active PFC, then you would need a battery backup that is pure sine wave....which tend to be more expensive. If your power supply is not Active PFC, then a simulated sine wave unit would operate just fine.'

Overall Review: O/S: Hymera Open 20090910 i386 (based on Debian Stable). Mobo: ASRock A780 Full Display Port RAM: Coarsair CM2X1024-5400C4 (2x1GB Dual Channel) CPU: AMD Phenom X4 - M/N: HD985ZXGHBOX Graphics: Nvidia 8800GTX P/S: Rosewill RP600V2-S-SL Also, the CyberPower website is superb. They provide very strong Linux support. The 32 bit .deb package installed flawlessly. And works like a charm. It's all command line, no gui. The unit arrived in the CyberPower factory carton and is very well packed inside. I plugged it in and let it charge overnight before I plugged anything into it, though I don't think that was really required. After hooking it up and installing the software (there are also a few command you have to run to configure the shutdown process, but the tell you exactly how to do it, very good documentation), I unplugged the unit and everything work like it should. The daemon shut down the system gracefully and after the specified amount of time running on battery.

Pros: None

Cons: Unit arrived DOA. Newegg replaced with a second unit following a hassle-free RMA. Second unit emitted a bright flash of light and a puff of smoke as soon as it was plugged in. Returned for a refund. This unit is a piece of junk. Cyberpower may make good stuff that others have used, but for me, they have lost my condfidence. I will not order another of their products again.

Overall Review: Newegg is wonderful. Becuse of shipping delays and because of my bing on vacation when the second unit arrived, it was after the 30 day time for returns as stated in Newegg's return policy. Nevertheless, Newegg allowed the return. When I told them the shipping costs of two returns had cost me almost as much as a third of the price of another new unit, they then sent me a free return shipping label, even though their return policy stated that all return shipping was at my cost. By their fair play and prompt response to my requests, Newegg has cemented our relationship. This is a great company with which to do business!!! As a side note, the customer product reviews really add value to what great service Newegg already giv es.

Pros: Pure sinewave, no-maintenance, outstanding build quality.

Cons: It's a bit noisy when it kicks on, and it's HEAVY.

Overall Review: I have a lower wattage model from the same series powering my gaming PC setup. I got this one to cover my entire home theater with game consoles as a surge protector/pure power source/short-term battery backup. It has kicked on without issue 2 times already during my 3 months of ownership during some power surges from stormy weather, and performed flawlessly. No lost data, no damage. Very pleased.

Pros: None

Cons: Unit arrived not functioning correctly. Upon plugging it into the wall and turning it on, the "power on indicator" never turns on, instead, the "boost" light remains lit. After unplugging it from the wall while the unit is on, nothing changes. The "boost" indicator remains lit and any devices I have plugged into the UPS turns off.

Pros: sorry newegg but i bought local due to the weight- i was concerned about S&H care. and thankfully, the return policy was hassle free.

Cons: bought 3 of these, all went into a buck mode with house voltage at 123v. output voltage was 108v. tech support told me to send them back- they believed something wasn't right.

Overall Review: i ponied up the extra $ for the SWT4 hoping the AVR would be more precise. read my review on that one.
