Internals
Opening the unit reveals a typical Seasonic design, but this time the heatsinks are arranged to better accommodate the 80mm fan setup. Seasonic normally cools this design with a 120mm fan blowing at the top of the heatsinks, so the heatsinks benefit in that case from a shape that will allow air to pass through vertically. This time the air comes from the sides and the back so they can be closed to the top.
There is a Nippon Chemi-Con cap installed on the primary circuitry, and the secondary features wildly placed OST RLX and RLS series capacitors. OST are often used by Seasonic, but they don't have the best reputation. In addition the caps are placed in between the cables and look like wild mushrooms growing in all directions. Internal appearance and performance are different areas, and it's possible to have an "ugly" interior while still providing high quality power. We'll see if that's the case here in a moment.

I´m also positive to the importance of reporting ripple figures, the standard is max.50mV ripple but lately there is a lot of psus sold happily stating 150mV ripple in their specs even though it´s out of the standard.If such companies voluntarily reports 150mV one can only guess how high the real figures are. Or how many more companies out there are a little bit smarter and state 50mV ripple even though the real figures are mabe ~200mV.
High ripple can damage many parts in the computer, lowers performance and rises temperature. So, yes, it's pretty important and should be mentioned in all psu reviews. Not mentioning it is no guarantee that the performance is really great.

50mV is the max specification on the 3.3V and 5V rails. The max spec on the 12V rails is 120mV.
