Just curious - VA (or "watts", if you ignore all the "reactive power" technicalities), is a measure of power, not of energy storage. 800 watts is more than enough for a single computer, and 400 watts is probably also enough (unless you have a Pentium 4 with a bad-ass GPU)... So isn't the more important question how much time will it supply this 800 watts? For an hour? For 10 seconds? So I think the relevant question is how much energy this UPS can store, and the relevant unit is Watt*Hour, or Volt*Ampere*Hour, or (like battery manufactures like) Ampere*Hour. -- Nadav Har'El | Wednesday, Jan 30 2008, 23 Shevat 5768 [EMAIL PROTECTED] |----------------------------------------- Phone +972-523-790466, ICQ 13349191 |Does replacing myself with a shell-script http://nadav.harel.org.il |make me impressive or insignificant? ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
