Review conclusionNot recommendedRecommended

Only in one review: Current 25 A (LS-300W-12V); Efficiency 91 % (LS-300W-12V); No load 0.9 W (12 V 300 W power supply); Weight 1100 g (12 V 300 W power supply).

12 V 300 W power supply: The claimed 300 W is not borne out: it is effectively a 200–250 W supply that enters protection when overheated.

LS-300W-12V: An excellent PSU: its ratings are borne out, with normal temperatures and ripple.

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.
