[QUOTE="Randy B. Singer, post: 1763208, member: 190607"] No, not at all. It is absolutely critical that one's UPS has AVR (automatic voltage regulation). Otherwise your UPS won't handle sags in the power, and those sags are very harmful to a computer. (Especially to your hard drive.) Just about all UPS's in the $100 and under range don't have AVR. In fact, before using the CyberPower units in the law office story I related, I purchased APC units (APC is sort of the General Motors of UPS's), and they didn't fix the problem. It turned out that they didn't include AVR. I returned them all. The CyberPower unit that I recommended is actually a really good value. It's an excellent unit with a bunch of really nice features for the price. I don't recommend APC units anymore because they no longer include AVR in many of their consumer-class models, even those that go for more than $100. [/QUOTE]
