Bests & Worsts Reviews from Amazon

I've had an APC Back-UPS unit for several years now and have been very satisfied. When other people in my rural neighborhood have had blown hard drives or mother boards due to "dirty" power, I've not had a bit of trouble. Buying a UPS is a wise investment to protect your sensitive electronic equipment. However, when I went to upgrade trouble started to brew. Recently, I purchased the BE750G directly from APC's website. I was uncertain about which UPS would work best with my computer, so I used the online wizards at the APC site to help determine the best UPS. The wizard asks questions about the type of computer you have (tower vs. mini desktop), monitor size, and what other type of peripherals you might have connected to your computer. The wizard will also ask you what type of processor you have. I entered all of this information into the wizard and was presented with the BE750G. Click... I made the purchase. Once the UPS arrived, I connected it to my computer following the directions and did a quick self-test of the unit. Within two seconds of clicking the self-test button in the provided Power Chute software, all power to my computer was dropped and it went off. I called APC tech support and they asked me what type of computer I had. I explained that it was a Dell Studio XPS 435T with the new Core i7-920 processor. The tech support representative did a bit of research and found that the power supply in my computer is not compatible with the APC unit I had purchased. I was told that the BE750G provides power in or as a "stepped approximation to a sinewave" when on battery power and that the power supply in my computer required a UPS that provides a "pure sinewave" when on battery power. It all sounded like Greek to me, I just knew it didn't work. Okay, so time to return this paper weight back to APC for a refund. But hold on, APC wants to charge me a 15% restocking fee even though it was their website that told me the unit would work with my computer! Aggravating! I'm still waiting to negotiate a peace agreement with APC over this, but have learned a valuable lesson. Do your research! Although the BE750G doesn't work with my computer, I'm 100% certain that it would work with older computers. I'm so confident of this that I purchased a second APC unit (SMT750) for my home office. This one should work. APC products good. APC sales... not so good.
