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 [email protected] || --- Talk Mailing List [email protected] https://gtalug.org/mailman/listinfo/talk
