A Closer Look
Short of a 20mm difference in length to account for the modular plug system, there isn’t much difference between the fully modular and non-modular units.
MWE Gold 750
Cooler Master’s MWE Gold power supplies have an aesthetically neutral white and black label with the Cooler Master Logo and series visible.
The rear of the PSU has the standard IEC-C14 power inlet and a power switch. The entire rear is vented for good cooling.
The other side has the information label. We see that this is a single rail design with all minor rails derived from the main 12V rail.
The top side is dominated by a large fan that takes up almost all of the PSU.
MWE Gold 750W Fully-Modular
The Fully Modular version of the MWE Gold 750 is 20mm longer but is otherwise identical. The Fully Modular design is reflected on the side label.
Outside of a slightly different part number, the specs are all the same between both models.
The same 120mm Silencio FP fan is used on modular and non-modular alike.
The rear panel looks a bit different on this version. The power switch is moved to the side of the plug and less of the rear panel is vented.
On the business end, we lose the single cutout with a pile of cables going out and trade them for the modular interface. You get 2 plugs for the motherboard 24-pin, three for heavy 12V devices like CPU EPS connections and PCIe power, and four peripheral plugs for SATA and Molex type devices.
Since both power supplies have the same length of cables, we’ll only cover this once.
The main 24-pin is rated at 610mm but retracts slightly due to the sleeving.
The CPU 8-pin (4+4 technically) is indeed right at 650mm, enough for all but the largest builds.
The pair of twin 6+2 PCIe cables have about 110mm between plugs and is about 590mm to the first set of connections. This could get a little short on cases with top mounted power supplies, but those are getting rare these days.
SATA and Peripheral cables are rated as 760mm to the furthest plug, and show around 100-110mm between plugs.
