On the Inside
MWE Gold 750
The Insides of these two power supplies are nearly identical, so many of these shots will overlap both models. One perk of using a DC to DC design is it makes for a compact platform that only has to generate one main rail. Dropping from 12V to 5V and 3.3V doesn’t take much space. What this does do is give Cooler Master room to use good filtering for clean and stable power.
We see a significant amount of filtering done immediately at the AC inlet. We see two Y-caps and an X-cap, and an inline ferrite beat to suppress any high-frequency noise that makes it in on the cord.
A couple of chokes, and more Y and X-caps rounds out some impressive filtering.
Cooler Master’s 120mm Silencio FP fan provides everything from a gentle breeze to a minor hurricane of 2500 RPM.
The fan is rated 0.16A or just under 2 watts.
Wiring is nice and neat with each wire or bundle of wires being sleeved with the appropriate ATX color scheme and the spots on the board clearly labeled.
Soldering is nice and clean. We see some primary MOSFET on the bottom of the board, but they are not heatsinked to the case with thermal pads like some designs.
On the modular end, we see the exact same PCB but connected to a daughterboard with all of the modular power connections. Other than this, nothing else changes between the models.
