Our first look at the insides show us this here rifle bearing fan. Basically, it's one of those improved sleeve bearing variants you may have heard about. I'll give this one a pass for any deductions.
That's definitely an Enhance based unit, right there.
Two X caps and two Y caps start off our line filtering, while a thermal pad hints at where the 12V output parts of this unit are located.
Enhance's soldering is flawless, as usual.
Eight of these power the 12V rail.
Near the 12V output parts, we find this PS223 protection IC. Wait... that's a good sized solder flake stuck to the board, there. And it's too far away from the line wires to blame on my de-soldering of said wires. Sorry Rosewill and Enhance, I gotta score on stuff like that.
The PWM controller is a CM6901.
Two Si8230BD isodrivers also occupy the bottom of the mainboard.
This is what helps manage the 5VSB output, right here... an SG30N04D. The unit, when the main power is online, feeds the standby rail from the 5V rail.
More line filtering here. Two coils, two more Y caps, two more X caps, and a TVS diode. Enhance doesn't pull any punches here.
The minor rail VRMs use the same 86350D and APW7073 Enhance has been using for most of their VRMs lately.
A CM6502 controls the PFC part of this unit.
Capacitors in this unit consist of Nippon Chemi-Con and Rubycon electrolytics and Teapo polymers. No argument from me.
Main switchers add up to four of these 5R190CEs.
The 12V output is heatsinked through the board using the heatsink around the transformer you see here. Given that the 12V output parts can withstand enough heat to cook a steak, I don't think we need to worry about cooling too much.
Soldering on the modular board is flawless.
On the other side of the modular board, we see a few Duratech capacitors.
Finally, we have the PFC parts hiding behind this big coil. Two 5R140Ps and a diode.
