Review conclusionRecommendedWith reservations

Only in one review: Voltage 12 V (12 V 5 A power supply); Under load 12.04 V (1205); Efficiency 87 % (1205); No load 0.35 W (1205).

12 V 5 A power supply: Low ripple and good temperatures at 5 A; synchronous rectification reduces heat, and protection is set close to the rating.

1205: Its performance is close to the 1204, but it runs hot under load; continuous current should be no more than 4 A.

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.
