Identify this power supply

[Shroomie]

It's a CompUSA '400w" supply purchased in June, 2005. All Teapos inside, but it looks good and sturdy. Nothing missing in there... Fairly heavy.

The UL number on the PCB is E206420. It's evidently registered to "DONGGUAN SHIJIE NEW ENERGY ELECTRONIC
FACTORY"...heard of it? They're in the "Wiring, Printed - Component" category somehow. I found that the Dongguan Shijie something-else Electronic Factory was Liteon, so perhaps I did get lucky (it's a CompUSA supply marked as a 400w, it's really a ~350. I lost the original cover though which is why I'm having to ask). This is the link that's got me thinking it might be a Liteon, it seems to be an associated factory producing keyboards...Although being Chinese it could be that it's just int he same town. I could also be on a wild goose chase entirely.

*sigh* Anyone seen one of these before?

(Note: I'll have pictures when I find my camera, which might make it easier.)

Delta also has a high-volume mfg facility in Dongguan. Maybe it's an independent company that has drawn on readily available talent. Or perhaps a contactor that has decided to produce under its own name. Quien sabe?

No.. I know Dongguan Sijie. They're a manufacturer of PCB's. Almost EVERYONE uses their PCB's.

Got a picture of the PSU?

Re: Identify this power supply

Ah, curses. I was afraid I'd find that out, Jonny.

Looks like it might use this PSU's case, but that's not the PSU. Different specs. Has me afraid, though...

Re: Identify this power supply

A number of CompUSA units are Sanhawk/Skyhawk. Mr. Wang often uses Dongguan Sijie PCB. Could it be?

That's it, there. I know they're fuzzy, I can't hold my camera steady and the lighting, well, wasn't that great.

Re: Identify this power supply

The heatsinks look to me like ChannelWell. Is there ‘CWT' on the main transformer?

Assuming the largest one is the main, no, but the one circled in red does have "CWT" on it. So this is the only Channel Well in existence without the dreaded Fuhjyyu caps?

Re: Identify this power supply

Channel-Wells have used a mix of other caps in the past, including CapXon, Canicon, Jamicon, Teapo, Jun Fu and of course, the ubiquitous Fuhjyyu (which aren't the worst out there, BTW). Those with CapXons, Jamicons and Teapos have been fairly reliable - not great, but not crap like Deer/L&C. There's a higher probability of a fan-failure than a bulging cap on an aging Channel-Well.

Re: Identify this power supply

Yes. I had a CWT MAV-250P (Nspire brand) with Rubycon 330uF 200v primaries, and Capxon secondaries iirc.

Re: Identify this power supply

The heatsinks are small & so as the O/P coils.
This PSU should be under 300W.
From the picture, we can't see the two bulk caps' rating.
Pls provide better pictures next time.

This is the Dongguan Sijie link.

I don't find any info about PCB production on their web!
China made PSUs are not necessarily inferior.
Tagan is also made in china too.

I have a 2.0 megapixel Kodak EasyShare and a shaky hand...

Well, it's served me well so far, but I'd certainly like to retire it to 300w duty powering a second PC. So now I guess it's down to one of these, probably the AMS. I'll be replacing this Radeon 9250 so I'll need it...

Anyway, thanks a lot folks.

Wrong company.

Dongguan Sijie makes PCB's. Dongguan Sijie is a very common name so it wouldn't surprise me if you found a lampshade company with that name.

Dongguan is a town in the Guangdong province (go ahead... that's worth an LOL) and Sijie is a commmon Chinese proper name, like "Jones."
