Seasonic Super Silencer 400W PSU Review

I opened up the power supply to get a closer look at the heatsinks and coils. All the heatsinks are aluminum which saves on weight. They are not the largest radiating elements I have seen in a power supply but their design provides a lot of surface area for heat dispersion. most of the weight of the power supply comes from the copper wrapped coils and large capacitors. If you look really closely at the exhaust fan you will see the rubber insulators that are supposed to provide some level of noise cancellation.
