Page 5 - Disassembly

Yate Loon is our fan maker today.

Yup, Enhance. Looks vaguely similar to the design used by the Silverstone ST85F-GS, though I can see quite a few differences already. This one uses traditional VRM daughterboards, while that one had the parts underneath the mainboard.

Enhance has always been good about line filtering, and this unit is no exception. Two Y capacitors and two X capacitors already, and we're not even on the mainboard yet.

Enhance's boardwork has always been nearly flawless. I see nothing to whine about here. You can see the PS223 protection IC and CM6901 PWM controller near the bottom of the shot.

We have more line filtering here. Two coils, two more Y caps, one more X cap, and a TVS diode. Excellent. I'm not going to bother pulling the primary heatsink out - I can ID all the parts but the bridge rectifier from here. Saving time... I like it.

That little daughterboard holds a CM6502 PFC controller. Four 5R280CEs make up the main switchers, while two 5R140Ps are found in the PFC section.

On the 12V output side of things, we find four 029N06N parts.

CoolerMaster boasts that all capacitors in the unit are Japanese, and so far that's been exactly the case. I've seen both Nippon Chemi-Con and Rubycon in this unit so far.

On the modular board, we find a few Suncon capacitors. You know them, but perhaps only under the name "Sanyo." Yes, they are Japanese parts.

Oops... I see one Enesol polymer. Not Japanese. Excellent quality, but not Japanese. Not that I'll be scoring on that... I only score on quality.

Our primary filter capacitor comes from Panasonic.
