Default Raidmax RD-350W

Raidmax RD-350W. 300w PC Power Supply.
Pulled this from a PC that i saved from being thrown out.
Label.....

Very simple looking label. (Almost like the power supply)
Top Side.......

As you can see, most of the "unnecessary" extra parts have been removed to save money.
Bottom side...........

For the most part, the soldering looks decent, except in a few areas.
Primary side..............

The X class capacitor is missing, however, there is a space for at least one.
In place of the Y class capacitors are two general purpose 2KV ceramic capacitors.
The rectifier consists of 2 RL207's and 2 1N5408's
The switching transistors are 2 E13007-2's and the 5VSB transistor is a 2N608.
The primary caps are 2 JEE 680uf 200v (both test near 500uf).
Secondary side...................


The 3.3v rail uses a 40N03P as a rectifier and a single JEE LOW ESR 1000uf 10v with no PI coil.
The 12v rail uses a F12C20 as a rectifier and a single JEE LOW ESR 1000uf 16v capacitor after a big PI coil.
The 5v rail uses a S30D40C as a rectifier and 1 SC LOW ESR 1000uf 10v capacitor before the PI coil and 2 JEE LOW ESR 1000uf 10v capacitors after a PI coil.
The 5VSB rail uses a 1N5844 as a rectifier and 1 SC LOW ESR 470uf 16v capacitor before a PI coil and 1 JEE LOW ESR 470uf 10v capacitor after the coil.
The -12v rail has a single JEE LOW ESR 470uf 16v capacitor after a small PI coil and the -5V rail has a single JEE LOW ESR 470uf 10v capacitor after a PI coil.
And the fan.......................................

Just some generic fan.
Overall this thing is pretty crappy but i'll keep it around since it's modifiable with all the extra spaces.
