the gutless, bloated, and fried power supply hall of shame
 
we have the build quality pictorial, but i'm thinking a montage of just pure destruction, missing parts, etc.

post pics of the WORST power supplies!

ps- i partially doing for a friend who im trying to get to quit using A-POWER... he might need some nasty pics to convince him of what he is doing to his customers.

Here's an SP-350 with busted caps (a very common sight on these forums). Unlike I'm used to on Smartpowers, this one had tiny 330uF primaries, rather than the usual 680uF. Both of them were bloated, as well as the standby caps.

I had some Deer DR-250ATX POS boxes....but I gave them to a friend. I heard he poured petrol inside them and had a little pyro fun :D

I bet the caps would have all exploded (Primaries usually make the biggest bang when I put them in fire)!

are you sure that is safe... those primaries are like little grenades...

There, have a look at all of leadman's psu's. They even took the covers off for ya.

Look at that one, just jumper through one primary cap, and put a 400v, 100uf fake UCC in there.

That one is actually quite impressive for a leadman.

wow look at those amperage ratings. I wonder how many companies rebrand that exact unit as a 600W.

I Just found the best site for pics burned/blown computer parts

http://www.halfdone.com/Personal/Job...and_Exploding/

Has pics of busted caps as well as burned PSUs, motherboards etc.

oklahoma wolf posted a couple that should be here:

Third one from the left blew first, the rest followed.

Damage to main filter cap.

If you look closely at the center of the pic, you will see a blown apart SMD transistor and a fried SMD resistor near it. There's another blown SMD transistor on the right side of the pic.

It took long term heating with a 60W iron to even desolder those parts during disassembly - methinks the SMD parts nearby didn't appreciate that.

smd components simply do not belong in power supplies... this is why. too many large components. the right way would have been old skool though-hole parts.

To be fair, that one is actually rated for 150w (the label pictured is from another PSU on that site), but still...
