The internal layout and arrangement of the components looks good. Half of the input filtering stage is on a small sister PCB connected to the AC input, but all of the necessary components are present. The filtering stage continues on the upper part of the PCB and right corner. The rectifier bridge has its own aluminum plate attached that acts as a heatsink. The PFC IC is covered with a yellow foil that we would have had to remove to take a picture, so we left it alone. The main capacitor is from Nippon Chemi-Con, a premium Japanese capacitor manufacturer. It is rated at 470µF and 450V.
The transformer looks like it was handpicked and marked with 85% to provide an extra boost to overall efficiency and power quality. Looking closer, we see that there's quite a bit of extra glue on the various parts; while that shouldn't interfere with performance, it does indicate that this is probably a custom-built preproduction model. The largest coil below the heatsink for example is covered with glue to secure isolating plastic parts around it. The heatsink has many scratches, which is another indication that this sample does not come from a normal product line.
