Review conclusionWith reservationsWith reservations

Only in one review: Current 12.5 A (12 V 150 W 12.5 A); Ripple 600 mV (12 V 150 W 12.5 A); Efficiency 86.5 % (12 V 150 W power supply).

12 V 150 W power supply: A decent supply with accurately set protection, though the transformer runs hot and the input capacitor is undersized.

12 V 150 W 12.5 A: It is generally decent, but ripple is high at maximum load and input capacitance is too low for reduced mains voltage.

Figures were taken from the review text and checked against the quoted passages. Measurement conditions differ between reviews, so read the reviews yourself before buying. Prices at the time of review.
