The Inside, Cont'd
The secondary side looks a little disarrayed since the cables are all just hanging around. In the 330W version pictured here, there simply aren't enough cables to cover the components below; airflow should not be an issue and all of the components should remain quite cool. The cable sleeves start inside of the power supply, with no special care taken to cinch down the ends of the sleeves. The small attached PCB on the left contains safety features like OCP.
What we don't really like to see is how the cables are attached to the main PCB. Normally it should be done with clean soldering and an additional shrinking hose in case the cables get loose. The S12II uses drops of glue to cover the soldering points, and we have definitely seen better in previous models of Seasonic.
The S12II is one of the first series of power supplies to contain small "solid" (Conductive Polymer Aluminum Solid) capacitors like what is now being used on graphics cards and some motherboards. We saw some of these in the Zippy Serene as well. The solid capacitor in the S12II is connected to the 12V rails, which Seasonic mentions on their packaging. Solid capacitors typically have better longevity and heat tolerance.

Doesnt mean they are bad. I know only from one manufacturer who is producing the exact same stuff for brands and that is FSP -> OCZ GameXstream.Seasonic put higher quality into their own units. The higher price is not just for the name only ;)
