Here's a nice overview of common issues in balancing linear vs. non-linear loads at home. You wouldn't think your little cluster is part of the problem but it can be.

The article is a bit dated. In the last decade or so server power supplies and high end UPSs have been power factor corrected or made to look more like a linear load. This has mostly been because of how power is metered and charged for. Older switching supplies would end up with a power bill that was higher than the actual power used. So if you have a lot of lower end power supplies you could be paying for more power than your actually using. -- Alvin Starr || voice: (905)513-7688 Netvel Inc. || Cell: (416)806-0133 alvin@netvel.net ||
