Review conclusionWith reservationsWith reservations

Only in one review: Current 30 A (5 V 150 W power supply); Ripple 70 mV (5 V 150 W power supply).

5 V 150 W power supply: Actual power is about 75% of rating; the inductor and diode assembly overheat at full load.

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

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.
