5V Results
With the 5V rail we again see slight problems at higher temperatures, especially at higher loads. Each load starts at a very nice, stable 5V but as the load increases the voltage drop is immediately visible. The results are all still inside spec and even at 100% load it doesn't fall out of line. It also held stable at this low voltage for an hour of full load. Even at normal room temperatures the voltage drop doesn't change much. At this point we feel PCP&C needs to work on keeping the 5V rail closer to spec, however, especially for a premium priced power supply.

Thanks, was of course wrong. I changed it now.
