Review conclusionRecommendedWith reservations

Only in one review: Under load 11.885 V (12 V 33 A 400 W power supply); Temperature rise 110 °C (12 V 33 A 400 W power supply).

LS-300W-24V: The PSU handles overload well, with high efficiency and low ripple, but its protection trip threshold is too high.

12 V 33 A 400 W power supply: Neatly built, but delivers about 100 W continuously rather than the claimed 400 W, and the transformer runs hot.

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.
