Review conclusionWith reservationsRecommended

Only in one review: In test 120 W (24 V 100 W power supply); Efficiency 72 % (5 V 20 A power supply (100 W)); Protection 24 A (5 V 20 A power supply (100 W)).

5 V 20 A power supply (100 W): Well assembled, but effectively a 75 W unit; the output inductor overheats at full power.

24 V 100 W power supply: It runs reliably at 100 W and handled nearly 120 W, though the author notes safety and component-margin concerns.

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.
