Now, we take the unit apart and find a rifle bearing fan. With a 10 year warranty, I won’t worry about it lasting.
A nice and clean CWT based platform awaits us on the inside.
Line filtering begins with one X cap and two Y caps. And me backhanding my D5100 for somehow missing focus on this shot.
Soldering quality is CWT’s best work today.
A CM6500 handles PFC control right here.
Line filtering continues with a TVS diode, two X caps, two Y caps, and two coils.
There are two GBU1506 bridges in this unit.
The PFC section uses two F22N60E parts and a diode.
Meantime, switching is handled by two 6R190P6 parts.
Looking at this angle, we can see that Corsair kept their promise about Japanese capacitors. Nippon Chemi-Con and Nichicon throughout.
The 12V output of the unit is handled with six IRFH7004 parts.
The 3.3V/5V VRM nearby is found bearing an APW7159C controller and six M3006D parts.
No soldering issues on the modular board either, that I can see.
The PWM controller, a CM6901.
Lots of cool parts are found here, including a PIC16F1503 microcontroller and a WT7502 protection IC. This is also where fan control happens.
Amid a forest of Nichicon polymer capacitors, we find the modular cable connectors.
Time to get some scoring done!
