Re: the gutless, bloated, and fried power supply hall of shame

What are you planing on doing to that PSU? Scrap it? Burn it? Throw it off an cliff?

While PSUs like this are not worth fixing to power a computer, as an Electronics Hobbyist, I find them to be a goldmine for various projects and repairs.

I had a PSU back in my first computer that was even more gutless than the above PSU. When I scrapped it for parts (that is, I desoldered everything from it), I used the parts to fix many other PSUs and electronics. And I built almost my entire Senior Project in university with parts from that PSU. So it has been extremely useful and I am glad I had kept it over the years.

Thus, if you are into learning or playing with electronics (be it as a hobby or a profession), you will likely find crap PSUs like the above very useful over time.

That transformer is just... Wow!

Yeah, my thoughts exactly.
I'll be surprised if it holds past 100-150 Watts of load.

Re: the gutless, bloated, and fried power supply hall of shame

Well, up to a point. First, parts from such craps are too weak for any decent units. Second, when you have dozens of such, it gets just too much to diassemble everything (and what to do with so many components? ).

Re: the gutless, bloated, and fried power supply hall of shame

I present the WORST PSU AT I've seen.
In the photo that I measured the voltage, I almost electrocuted, because of the camera, I did not fix and I did not put the hand correctly with the tip of the multimeter. XD.
Kids, do not do this at home xD.
Going back to the subject, I find it VERY regrettable to leave a huge hole where the input of 220V DC ...
In addition, the primary capacitors bloweds...

200W from that? Not with those light weight heatsinks! And with just 220uF input capacitors the hold-up time would be horrible. The thing is over 20 years old, time to send it to the recycler.

I also think the same.
This source will probably pull it to the scrapping. But before throwing it I wanted to share photos.

Re: the gutless, bloated, and fried power supply hall of shame

Absolute most of AT configurations won't even ever reach 100 W so the unit does not need to actually provide 200 W. That's why they went away with these craps.

Re: the gutless, bloated, and fried power supply hall of shame

that might be worth $0.02 in scrap.

That might actually be worth a fix.

Re: the gutless, bloated, and fried power supply hall of shame

it will burn itself soon enough.and the pc,house,whatever its in.
nice puddle of brown glue right across the unfused side of the ac input.
nice firestarter.

Basiq 500 recap

This was a bitch. It used special-made 8x25 6.3 2200u caps, one wrapped in heatshrink was in particular bad area. I was not able to find any 8 diameter caps for the 6.3's so I had to use 10, and BARELY make it in there, but it was shorter, and I double shrink wrapped it cause it was in tight contact with a fet heatsink

Not user serviceable? surre


bad 3.3v


one of many


two extra


I love living right next to mouser (Mansfield TX, mouser HQ)


double heatshrinked panny


looks much better, don't you think?


passed


and in a C2D system working flawlessly, so there is no problem with handling a pull

Re: the gutless, bloated, and fried power supply hall of shame

8mm caps for Voltage Filtering are generally a bad idea...
And that FSP Plattform had its problems...
Though it looks like a newer revision...

FSP, most likely GLN platform. I can see GLY, yep, pretty much the same.

Though my new 1200/16 and 2200/6.3 D8x20 mm Rubycons make any Panasonics just a dogs food. You should consider sourcing some too, I bet I'll be cheaper even with shipping than all those overpriced corporations.

sourcing?

http://www.thefreedictionary.com/sourcing

and than cap stock

[Uranium-235]

Re: the gutless, bloated, and fried power supply hall of shame

so I should buy caps from Czechoslovakia?

Wut?

Re: the gutless, bloated, and fried power supply hall of shame

Show a little grace, Behe. Many Americans are still getting used to Yugoslavia having re-Balkanized.

That reminds me ... would a Yugo now properly be called a Serbo? A Croato? A Bosno? (Please! Not from Herzegovina or Macedonia!)

[Uranium-235]

Re: the gutless, bloated, and fried power supply hall of shame

I don't pay shipping for caps, I pay tax because they're bought in-state

I also buy other stuff from them, I got a USB connector for a case, some other parts, a sata connector for a DVD drive controller board

Re: the gutless, bloated, and fried power supply hall of shame

Hi guys, not the worst but for a 2 month old PSU from Corsair model CX650M deserve to be here. Fail description: Short FR157 diode,completely short circuited CEF04N7G Mosfet, short Zener Diode marked ZD4A, 4 blown resistors and destroyed PCB trace. Currently trying to identify values of bown glass zener diode printed ZD4A.

Re: the gutless, bloated, and fried power supply hall of shame

Yeah this platform is not that great, but if it's only two months old, it is under warranty, no?

[PCTechnics]

Re: the gutless, bloated, and fried power supply hall of shame

Hi Behemot, was purchased in other country so no warranty here,is from a friend that gave it to me, im trying to fix it.
