The Inside - Primary Side
Once open the inside reveals very limited and packed space. The heatsinks are mostly located directly behind the openings in the back, allowing them to immediately catch the incoming air and get optimal cooling. The entire secondary side looks very packed and there's little room left for airflow to cool down the components in that area.
Directly in front of the fan is a coil that's part of the primary side's PFC stage. This coil sits directly in front of the fan and blocks a fair amount of space. We have to wonder how much turbulence is caused by this design, since the rectifier bridge is also located beside this coil and blocks additional airflow with its cooler.
It's quite clear that with this topology Zippy isn't able to fit a 12cm fan into the chassis. If it were located above all the components there really wouldn't be any space for the air to come out of the PSU. As it stands, there is still space above the coil and rectifier bridge to allow the air from the heatsinks to reach the exhaust.
The filtering stage looks to be of the utmost quality, and we can see all of the components needed for filtering.
The PFC IC is wrapped in a yellow sheath, whether for protection or for some other purpose we're not sure.
The main capacitor is made by Nippon Chemi-Com, a Japanese company regarded as producing some of the best capacitors in the industry.

When will you test some Seasonic PSUs?USAF1 - Monday, September 3, 2007 - link
Yeah, I'd love to see the Seasonic S12 Energy+ series tested. Seasonic claims a peak efficiency of 88%.Christoph Katzer - Monday, September 3, 2007 - link
Will come this week...USAF1 - Monday, September 3, 2007 - link
Sweet...InternetGeek - Monday, September 3, 2007 - link
89% efficiency means the PSU doesn't dissipate almost any power at all as heat or whatsoever. This is a legent waiting to happen in terms of PSU ;)Christoph Katzer - Monday, September 3, 2007 - link
Quite possible. First it was with 230VAC where we have seen already 86% and these 2.7% more is definitly possible. I have seen already 3 years ago efficiency of 89% from a handmade PSU sample at Topower's factory in China.
