Corsair pulled 335W from the same model under the raidmax name before the primary switchers went out.

Yes, and their last words were "That was spectacular!" .

Never noticed that until now . Fuse doesn't look like it's blown, though.

I posted this picture in another topic, but I might as well post it here as well. Behold a cheapo Nintendo DS charger, after a fatal short-circuit...



(note the exploded IC and the soot on the caps)

Also the diode leads had blown out pits as well.

I just got a dead "TT" branded PSU from a repair, where there are massive burn marks near the wires on the secondary side, Caps are all bloated and it took the motherboard out. Pics coming soon.

Just realised all the glue on the caps, but they're going to need more to stop them leaking.

Its got some potential with those heatsinks.

That seems to be just like my "Super Talent" power supply that I posted about a while ago somewhere on this forum. After a full recap, upgrade of the secondary rectifiers, and upgrade of the primary filtering and bridge rectifier, it works great.

That's some nasty heat damage near the secondary caps...

its the opposite of a linkworld i just gutted, great filtering and wire, good rectifiers, etc. but he caps were bad and the heatsinks were TINY! good for parts only.

How is this powsun(leadman) working btw? It doesn't have 5vsb transformer, so everything must be on one transformer? And I don't see 5vsb switching transistor or ic. That would mean all rails are turned on all of the time?

edit: There is an ic on primary side, but I believe it's a pwm controller.

Good question. Perhaps there's only one rail that's constantly present and all of the voltages are generated from that rail. That's just a guess, though.
Or maybe that's not an ATX PSU?

that's actually supposed to be a 150W PSU. not 250W.

still.. interesting question..

Maybe it's designed for Pentium 1 systems?

It's ATX, it has 3.3v (the orange wires) and 5vsb wire (purple) as well as ps-on (green wire) and ps-ok (grey wire).

The 5vsb is probably produced by the circled transistor or maybe IC in to-220 package.

This is on secondary side, so I think it's a rectifying diode for 5vsb. Still not clear how it works on primary, though.

Here's another one. Four diodes, small transformers and small heatsinks. Primary caps are fuhjyyu, secondaris are nicon (no, I didn't mean nichicon) and Fcon.
