If we listen closer with this power supply, this unit is silent
at 20 percent load. The GPS-700A8 uses a fan from Globe Fan that is based on a
sleeve bearing and overall this fan is rather cheap. When demanding 50 percent load from this unit, the noise level
can be described as audible and when there is 100 percent load, the unit is well
audible.
