Review conclusionRecommendedWith reservations

Only in one review: Current 16.7 A (12 V 200 W power supply); Efficiency 84 % (PTA-200W-12V); Protection 28.8 A (12 V 200 W power supply).

12 V 200 W power supply: It survived a 130% load test at about 265 W, proving surprisingly robust, though ripple remains noticeable.

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.
