Power supply build quality pictorial.closed.use part 2

I have a Raptor LC-B400 that looks very similiar to this psu. Does anyone know what the "chip of the year" marked 2005 is? I thought it had something to do with proprietary markings, the transformers also are marked with a number including 2005. I was not able to find a data sheet for the IC.

Well I decided to name that IC "chip of the year" because the numbers on the IC seem to be somewhat related to the year the PSU was built. I took apart 2 L&C PSUs last year and from what I remember, one was from 2003 with the IC marked 2003, and another was from 2005 with chip and traffo marked 2005. But maybe that was just a coincidence.

I think somone mentioned it on this forum before that those ICs are just cheap TL494/DBL494 variants.

Raidmax Aurora 2 "600w", have been told this is really just a 500w Andyson, and the box even advertises the fact that ripple on the 12v is barely in-spec, and that the ripple on the 3.3v and 5v is OUT of spec.

Old LCT Tchnology 250W AT PSU, must be at least fifteen years old, surprised it still runs.

Dell 160W Optiplex GX-270 slimline PSU. Still works great.




Pic of the OST primary caps.





Austin 280w PSU, infected with capacitor plague, had some cool multi-color fans that I ripped out of it.





Primary caps.



Failed caps, one had electrolyte leaking out of it.



This has been silkscreened for about a billion different designs.



Yay chip of the year!



Powertech 200W PSU, pulled out of a Gateway G6 333





Rubycon primaries.



Delta could be the OEM, don't know for sure.



Dell 200W, pulled out of an 11 year old Dimension, seems to be of high-quality, too bad it's got that stupid DELL wiring, any way to use this on a standard ATX mobo?






Primary caps.



Lite-on OEM

I usually reduce my pics in Paintbrush when I'm lazy.

Most likely, yes. Either rewire the Dell 200W mobo connector so that it has the same wiring as a standard ATX connector or desoldier another ATX connector from a junk PSU and soldier that in the Dell 200W.

cheese007 > See thread "Old Dell PS 5201-7D 200 watt psu" posted in this forum 2-10-2009. A good discussion on this non-standard wiring configuration, what you can do, and website information giving the color codes for the wiring.

I have one sitting on the shelf - will probably use it for parts - too much trouble to rewire.
