Delta Electronics GPS-350CN-100 need repair

Re: Delta Electronics GPS-350CN-100 need repair

I yank out the heat sinks before tossing them. but thats about it.

That's like saving a small piece of aluminum foil. Worthless! At least that's how it is for the cheap PSUs. Unless you save the components on the heatsinks too ("diodes-on-a-bracket" rectifier anyone? Oh Deer! )

The IEC power plug and rocker power switch (if there is one) are probably the most useful stuff for me. Followed by the primary and secondary HS silicone, fan, and many of the larger resistors (>1/2W). And wires sometimes...
So I just save the whole thing.

I am working on an oldschool HP lab DC power supply right now. The thing was dropped and had some parts smashed, including a 22 Ohm 1W resistor. But my junk PSU pile came to the rescue yet again! Found me a nice 22 Ohm 3W load resistor in one PSU. Also pulled some (crappy) caps to (temporarily) replace some of the 50 year old caps in that HP lab supply for a test to see if it works. I should be getting to that in a few days.

I save the heatsinks on PSUs too. I usually just put them in a case box and once I collect a box or two full of them, I take the box to the metal recyclers, and they will give you $50 or so.

There goes another Bestec ATX-250 12E. You learn SO MUCH by fixing one of them, but they are otherwise worthless.

Case box for what? A PSU? If you get $50 for that, then you all must be getting some really good prices for scrap down in Australia.
In my area here, you'll get that much only if you bring a half trunk full of copper. It's absolutely pointless to recycle anything for scrap here. Case in point: my friend had two large moving boxes full of Xbox 360 and PS3 heatsinks. He asked *several* local metal recyclers how much they'd give him for those boxes, and they said $10-$20. Not worth even hauling it to them! I gave him $5 for a smaller box he had (hence why I have Xbox 360 heatsinks on every computer ghetto mod of mine ).

Re: Delta Electronics GPS-350CN-100 need repair

... I assumed the single 3300uF capacitor for 12V without any pi coil would be insufficient in ripple suppression at high loads, so I moved some 12V cables to make space for a second capacitor for 12V. I used 2x2200uF instead of the single 3300uF capacitor ...

^ That's brilliant!

Thank you! I love Delta power supplies!

I meant the cardboard boxes for an ATX case. I have one of those full of PSU, chipset and CPU heatsinks (only all-aluminum heatsinks. I keep and reuse the copper cored ones). I've just started filling up a second box with them. I'll take the two of them in once I fill it up, and I should get at least $50 for the two of them.

Yeah just about that lol You have enough of them all the time if you really *need* some for whatever purpose…other than that you can just sell them for metal. I had tens of such crappy PSUs and I already had to disassemble them too at least for steel, aluminium, cables and transformers to save space.

I save the heatsinks for electronic projects not to scrap them for cash. a lot of new psu's don't even have heat sinks on the rectifiers
