I noticed that when there were fluctuations in the power they were very little and far between. All the voltage rails are extremely stable under both configurations, which in turn will help in keeping the system stable as well. I was interested to find out why the 12-volt rail reacted that way under full load so I contacted SilenX's technical support. Within less than two hours I received a reply to my e-mail, and SilenX explained that they calibrate the power supply while it's under a full load of 12A on the 12V rail. Since most computer enthusiasts don't put that much load on the 12V rail, which would explain why my readings were a little low. They also added that they recently lowered there load levels as some readings were high, they are still trying to find the ideal middle ground for a default configuration.
