Our first stop in the disassembly page is to look at a sleeve bearing fan, right here. I think I will be scoring that... at the very least, a plain Jane ball bearing model would be preferable. That said, I do have a few Yate Loon sleeves running in the mining room, and the only time I've had one go down is when I wasn't paying attention and stuck my thumb into one as it was running. A broken off blade and a Band-Aid later, I had it replaced.
See, it's been months since I was able to sell most of these review units, so I quit trying to do that and started pulling these fans out for the mining rigs instead. They've been surprisingly long lasting in that environment, running wide open all the time. But I'm still going to score on it, because I feel like being obstreperous today.
A look at the unit's innards shows us the same platform as the first version of the CXM.
Line filtering starts with two Y caps.
The soldering... is not the best CWT has had to offer. It's not the worst I've seen, but I think I'll be docking half a point. CWT isn't usually this sloppy anymore, when it comes to their Corsair units. Corsair keeps a tighter leash on them than many other companies using CWT, but I guess the odd blip still gets through every now and then.
More line filtering. Two more Y caps, two X caps, two coils, and a TVS diode. Looks complete to me.
The unit relies on two GBU1006 bridges.
A CM6800 provides PWM and PFC control. I don't care for the use of the Jun Fu cap on this board, but this is a relatively non critical location. I may score on that, I may not. Depends how good the rest of the caps are.
And we also have a CM03X on the back of that daughterboard.
Here, we get a look at the remaining capacitor compliment. Most critical parts are Japanese - Nippon Chemi-Con. The non critical stuff is either Samxon or Taicon. I can live with that. This is another improvement on the original unit, which relied a little more on Capxon parts.
The 12V output is provided by five AP9990GH parts.
Again, most of the critical filtering is done by Chemi-Con, including the 12V output.
The back of the modular board shows us the minor rail VRM and some more less than perfect soldering. The VRM uses an APW7159C controller and six AP72T03GH parts.
All capacitors here are polymers from Apaq and Enesol. No worries here. I'm glad to see no wires were harmed in the mounting of this board, as was the case with the last CXM 750.
The primary heatsink. Two K13A50Ds for switchers, one diode for the PFC, and one CEF04N7G on the end for standby.
Finally, the PFC heatsink and its two G20N50Cs.
