Review conclusionWith reservationsWith reservations

Only in one review: Current 5 A (Used 12V 5A power supplies); Test current 5.5 A (Used 12V 5A power supplies); Under load 12.07 V (Used 12V 5A power supplies); Temperature rise 58.6 °C (12 V 60 W power supply).

12 V 60 W power supply: Essentially a sound 60 W supply with acceptable ripple and temperature, but its protection current is much too high.

Used 12V 5A power supplies: The boards ran stably and stayed moderately cool, but component quality and condition varied noticeably.

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.
