We shall begin our disassembly with a ball bearing fan from Yate Loon.

And now, here’s the inside shot of what looks to be an FSP built product.

It is likely I won’t be able to get a good look at all the working parts of this thing thanks to where the control daughterboard is, but I’ll do my best.

Soldering quality is top notch in this unit, so I won’t pull points for that later. An 8R2K8CE and an 03N8 can be found on this side of the board, with the 12V output parts under that thermal pad on the left. I’ll just remove it.

Here are your five 12V output parts. There’s really no room for heatsinking on the other side of the board, so these will get all their fannage through the transformer and coil below them, with more cooling from the housing.

Two Y capacitors and one X start our line filtering.

And the mainboard continues it with a TVS diode, two more Y caps, two coils, and two more X caps. Looks good to me, even if it’s all wrapped in black.

On the primary side, we find a diode and a 60R180F for PFC and two 25N80K5s for switchers.

The control board is sandwiched so tightly in between the transformer and modular board that we can’t see much of it, and de-soldering isn’t going to work well with the aging gear I have, so here’s about the best look I can give you of it. An ISL6608 MOSFET driver can be seen just above the coil on the left side.

And there’s another IC of indeterminate part numbering shoved way back in here beyond some of the Japanese capacitors. I saw both Chemi-Con and Rubycon electrolytics in there.

This is the minor rail VRM, which uses an APW7159C controller. Each of the 3.3V and 5V outputs get one 060N03L and one 040N03L. An APW9810 can be found in the very top left corner of the VRM.

Finally, here’s the modular board. A lot of the polymer capacitors on the mainboard are Chemi-Con, but here we find G-Luxon parts. I’m not too concerned about the quality of these, but because these are effectively Teapo parts the unit can’t quite claim to having all Japanese parts anymore. At least they’re decent.
