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

A dead Athena Power "Hercules" Model: AP-MPS3ATX35
This power supply came out of a PC i'm fixing up.
From what i've been told this PSU was purchased from Fry's Electronics less than 10 years ago.
So this is going to be the first PC power supply i'm putting here so apologies if i make any mistakes.
Anyways, on to the power supply.
Label...

Does not look bad but it will be in a moment.
Top Side....

Heatsinks don't look too bad but you may notice some stuff off about this supply.
Bottom side.....

Soldering does not look very good.
Primary.........


This does not look very good.
The switching transistors are 2 13007's (how suprising) while the one for 5VSB is a BU3150.
The wires on the common mode choke look a bit thin.
There's no varistor and the glue appears to be hot glue.
The capacitors are Cheng LS 470uf 200v
Time for the best (or worst) part, the secondary....................


The s20c45c diodes are for the 3.3v and 5v rails.
The f16c20ct diodes are for the 12v rail.
All of the capacitors are EJICON KF.
The 12v rail has one (badly soldered) 1000uf 16v capacitor with no PI coil.
The 5V rail has one 1000uf 10v capacitor with no PI coil.
The 3.3V rail has one 1000uf 10v and one 220uf 16v capacitors with no PI coil.
Both the -12v and -5v rails have one 220uf 16v after a small coil.
The 5VSB rail has one 470uf 16v cap before a coil and a 1000uf 16v capacitor after a small coil.
This does have a fan speed controller but the temperature probe had a 1cm gap between it and the heatsink.
Speaking of the fan, here is the fan............................................... ........

Just your typical cheap fan.
Not much else i can say about this unit other then it's trash.
