Great review man.

Looks to be a pretty fair power supply.

Is it only available in Europe?

[c_hegge]

Nope, It's only available in Australia

"While there are certainly worse parts out there," Has your opinion changed on Teapo much?

[c_hegge]

Yeah, I've softened a little over the years towards them. When I said that, though, I meant that there could be Fuhjyyu or something like that.

[Wester547]

You don't regularly pull them out of 2-3 year old PSUs and find them bulging (or failed) anymore?

[c_hegge]

Nope. Come to think of it, I've only seen one or two power supplies with failed Teapo capacitors this year. They were also kept away from hot components in this unit and they all felt cool to touch when I opened the PSU up, which is more than I can say for some other power supplies. I still recapped it before I put it back together, though.

This power supply’s input filtering starts at a PCB attached to the AC receptacle, with two X-Capacitors, a coil and two Y-Capacitors. The main PCB contains three X-Caps, two coils, two Y-caps and one MOV. The total component count is five X-Caps, two coils, four Y-caps and one MOV – which is plenty of components.

…1 + 2 = 2!?

Anyway, there's one common-mode choke on the main PCB, plus provision for a second (and another pair of Y-caps) that wasn't installed, and the main PCB has four installed Y-caps (or five counting the one on the non-isolated DC bus, which is present in almost all units; of those on the AC side, one pair is between the installed choke and an X-cap and the other pair near the fuse).

[c_hegge]

Whoops. Nice job spotting the extra pair of Y-Caps. I didn't notice the ones near the fuse. There are only two coils in total. I was thinking of the total count when I wrote the number of coils on the main PCB.

Whoops. Nice job spotting the extra pair of X-Caps.

You mean Y-caps.
