This looks to be the new Leadex II platform, made by Super Flower, which offers improved performance compared to the G2 series' Leadex design. We already saw this platform in EVGA's 850 G3. Only the 5VSB circuit remains the same (though our sources say the OEM is already working on an update featuring a more efficient 5VSB regulator).
Super Flower uses a 130mm HDB fan since a larger-diameter one wouldn't fit in the compact chassis. The resonant controller is not the one we saw in the 850 G3 (SF201T), but rather an IC code-named SF29605. On the secondary side, a mix of Chemi-Con electrolytic and polymer caps filter the rails.
The build quality is generally good. However, we'd prefer capacitors with a longer lifetime on the modular board instead of the KRG caps. Fortunately, stress on the caps is low in this region since most of the ripple filtering takes place on the main PCB's secondary side.
