Your photos are all error 404.

...But from what I can see in those thumbnails, it's a typical half-bridge/flyback ATX 1.3 PSU, a la SunPro KY-400ATX. What's somewhat comforting is that it actually has an EMI filter and PFC coil.

You're probably looking at around 250W max, likely less, and 2-3 years of barely passable service if you're nice to it.

Two 12 V lines 8/12 A. 5V 12 A. 3.3 V 14 A.

It can deliver 240 V where it matters. In comparison my 400 Watt PSU can deliver 380+ watts on 12 V lines (when properly cooled of course).

It can deliver 240 V where it matters.

Sounds like a killer PSU. Quite literally.

Thole holed-drilled-in heatsinks always make me think of Leadman. Which are usually pretty spectacularly bad.

If you are willing to let it near your computer at all, don't ask it to deliver more than half its rated power. But 200W will actually power a basic motherboard with integrated graphics.

But it's basically like driving around with bald tires: they'll work fine as long as everything goes well, but can fail rather spectacularly if conditions worsen.

Thanks everyone! I've fixed the images links
The OEM should be Hedy and the original model PP355ECA rated 250W
BTW the same brand (Kraun) distribuite a "500W" PSU that's EXACTLY the same "400W" without PFC coil

Yeah, some companies slap the most out of this world ratings on the most shoddy PSUs. I guess since there's no regulatory body that decides what's acceptable or not.

You'd have to list the semiconductor part numbers for a theoretical max power calculation.

But judging by the 220uF input caps, I'd say about 150 watts on a good day . . . with the wind blowing in the correct direction . . . while it was going down hill.

So true. Imagine going to a car lot and seeing a sticker on a hummer that lists its in city fuel economy as 65 MPG. That is just about what some of these companies do. I can live with a little fudging, but seriously? 600 watts when you cant do 200? At least it gives us the gutless wonders to blow up and laugh at.
