Time to take apart the Enermax. I'm going to put some tinted goggles on to prevent the recurrence of blindness.
My eyes! The goggles do nothing! You should be looking at a fan hub picture above.
Eep. All the heatsinks are blue. The color scheme on this unit is like mashing your hand down at random on a piano keyboard and calling it a song. And then auto-tuning a <insert flash in the pan would-be superstar here> song from it.
As always, the AC filtering starts here. This little board holds one X capacitor, four Y's, and a coil.
The underside of the PCB reveals some sloppy-ish looking soldering in places, but this isn't worth complaining about. As Enermax units go, it's actually improved from some other units from them I could name.
What the... what's happening at Enermax HQ? First our dear Anita Chiu gets replaced by Lora Lo, and now this. Who is Iamcmf? What is Iamcmf? People, I worry that our friends in the engineering department over at Enermax are slowly being replaced by aliens, for this name is clearly not intended to be uttered by the human vocal apparatus.
In this shot, you can see the two VRMs that supply the 3.3V and 5V rails, as well as the wee blue heatsink that holds a 20A bridge rectifier.
The back of the modular connector panel holds a lonely polymer capacitor.
Topology for this unit turned out to be of LLC resonant design. Controllers used are the CM6901, which can also be found in the Seasonic X series units, and a CM6502 for the PFC duties.
A close-up of some of the 12V secondary filter caps. The polymers appear to be Enesol brand, while the electrolytics are Nippon Chemi-Con.
The one big blue heatsink I left in the unit houses the 12V secondary parts. There are four IRFB3206 parts on it, two for rectification and two for freewheeling, and a diode for the 5VSB circuit bolted to the sink.
One of the VRM control chips. Each VRM is handled by one of these, an APW7073A.
Primary capacitor is this here big bad Rubycon.
It looks like Iamcmf is also responsible for the modular connector board. Alien or not, it looks like he/she did a good job.
This is the PFC heatsink. Two K20J60T's and a diode.
The primary heatsink. One 2SK3067 and two G20N50C's for switchers.
Just before I put the unit back together, I spotted this near the two VRMs. It appears that Enermax provided for a way to adjust the minor rails, as well as a 5V sense line that wasn't used.
