Review conclusionRecommendedWith reservations

Only in one review: Current 16.86 A (12 V 200 W power supply); Under load 11.94 V (12 V 200 W power supply); Protection 18.1 A (12 V 200 W power supply).

12 V 200 W power supply: A successful model with 90–91% efficiency and good temperatures; the author found it especially interesting.

PTA-200W-12V: This budget supply handles about 216 W, but its rectifier and choke get hot, and low-frequency ripple is high.

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.
