Popping open the casing was easier than most, but still involved voiding the warranty so be careful if you’re interested in doing the same.
While the angle isn’t great, we can see from here that there are three ferrite coils along with a pair of ceramic Y capacitors. The X capacitor sits just between them with the goop covered metal oxide varister sitting just behind this collection. A good start.
Everything is neatly laid out with a nice channel created by the heatsinks to drive air across the important components. The large, single, Japanese capacitor (Doc Brown would have a heart attack) is obvious once inside. Solid capacitors arn’t used in any instances, but those are more of a motherboard marketing gimic than a PSU one since few actually look inside their units.
While there isn’t a label to be found on the largest, the packaging suggests that the single large electrolyte capacitor is produced by Rubycon, whereas the smaller ones found in the secondary portion of the unit are made by Teapo.
