The EDT1250EWT's platform is identical to the one Thermaltake uses for its Toughpower DPS G RGB 1250W. However, the PSUs differ in their fans. Enermax doesn't offer RGB lighting, and instead implements a more reliable twister bearing.
As you can see in the picture below, even the mini-USB connector is installed on the modular board. Enermax simply chooses not to utilize it. On the other hand, Enermax does provide that small display, which reports power consumption in real-time.
The following video shows the MaxTytan’s internals.
