Dissection – Part 2
Disclaimer: Power supplies can have dangerous voltages inside them even after being unplugged, DO NOT OPEN POWER SUPPLIES. It’s just not a good idea. Opening a power supply and poking around inside could very well kill you. Don’t try this at home. Don’t try this at work. Just don’t do it.
The three primary caps are all Panasonics:
On primary switching duty are four K18A50D (18a, 500v) MOSFETs:
Subtle markings are subtle.
On the 12v rectification end of things we get eight K18A50D MOSFETs (40v, 120a):
Here’s an overview of the secondary bits:
5v and 3.3v both get four APM2556N MOSFETs (25v, 60a) as you can see below:
Overseeing all this is a PS238 supervisor IC. It supports all the various protections as well as six rails of 12v OCP, quite the chip really.
The soldering on this operation is really quite good. There’s a fair bit of hand soldering done, likely to make sure all the joints are solid enough to make Platinum.
The closest thing I can find to an issue is too much solder on a number of the joints, these are the worst offenders:
When that’s the worst you can find, things are looking good!
All together this is a well designed, well spec’d and well put together unit that Enermax has come up with!
