Review conclusionWith reservationsRecommended

Only in one review: Current 10 A (12 V 120 W power supply); In test 180 W (MeanWell SDR-120-24); Test current 8 A (MeanWell SDR-120-24); Under load 11.84 V (12 V 120 W power supply); Efficiency 89 % (MeanWell SDR-120-24); No load 0.5 W (12 V 120 W power supply).

12 V 120 W power supply: A good supply, but in practice it is rated for roughly 100–110 W rather than the claimed 120 W.

MeanWell SDR-120-24: The PSU passed the tests; the author liked its build, protection and stability, though the transformer gets quite 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.
