Only in one review: Efficiency 89 % (12 V 150 W power supply).

12 V 150 W power supply: Efficiency is about 89%, but the snubber and power transistors overheat at 12 A.

12 V 150 W power supply: The board handles its rated power, but 80 μF input capacitance is insufficient at 115 V and ripple is high.
