Since there is no fan, there's not much point in measuring sound pressure levels, but what about noise from the electronics? There is an audible "chirping" from the PFC choke and both DC-to-DC converters. However, this could be an individual case. The difference between the ambient and the exhaust temperature is relatively high. We've tested the power supply with a room temperature of just 22.1 °C, which is usually no problem for a high-quality PSU.
The voltage quality is absolutely acceptable. Small transients are no big deal and the smaller rails are always below 25mV which is less than 0.5% ripple. +12V shows only 51mV, but we should keep in mind that Seasonic had no more than 20mV on all outputs. Overall the voltage regulation is decent. There is hardly any drop on the +12 V and +3.3V rail but +5 V could be closer the optimal value.
Considering the 80 Plus Gold certification, we expected high efficiency and that's exactly what we got. The only blemish is that 5% load "only" comes in at 71-74%. At this point the efficiency could be better than 75%, but we don't want to overdo things.
