I'm familiar with using the +12V and +5V rails on my PSU to get +7V. +7V or a bit lower would be just about what I need. But could this be bad for the PSU at higher amperages, particularly with not much draw on the 5V rail? If the 5V rail floats up a bit high (and the +7V "rail" correspondingly lower), it's no problem (nothing sensitive being powered), but I don't want to fry the PSU.
