Review conclusionWith reservationsWith reservations

Only in one review: Current 30 A (5 V 30 A power supply (150 W)); In test 180 W (PTA-150W-12V); Test current 34 A (5 V 30 A power supply (150 W)); Under load 4.89 V (5 V 30 A power supply (150 W)); Protection 34 A (5 V 30 A power supply (150 W)).

5 V 30 A power supply (150 W): Delivers about 75% of its rated power; ripple is acceptable, but the inductor and diode assembly overheat.

PTA-150W-12V: A decent budget supply for undemanding uses, but input capacitance is low and low-frequency ripple is significant.

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.
