I wouldn't think it would be enough to overload a power supply unless it overloaded the -12V > line which is usually only rated in the mils. What is the average 12V rating? 5-8 amps? and even more for 5V? I forget what the > average -5V line is rated. The problem is the +5 standby supply. In a modern ATX evironment lots of stuff pull power on that rail when the machine is switched off, and most ATX supplies only can delive .5-.7 amps here which can easily be overwhelmed. BTW you all know that you ATX machine use about 25W even when switched off right ? This gets into real money if you have a handfull of machines, and you get absolutly nothing for it :) -Søren To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
