The efficiency measurements confirm that the PSU meets the 80 Plus Bronze
efficiency requirements at 20% and 50% loads.

- Voltages were within the specification except for the -12V rail which went outside
approved limits when the PSU was under a heavy load (>300W). The -12V rail is
not used very often, especially in new motherboards. There are three type of
devices on old motherboards that require -12V which are RS232/RS485 ports
without build-in circuitry for generating the negative voltage, (mini-)PCI slots and
