Review conclusionRecommendedRecommended

Only in one review: Voltage 12 V (12 V 100 W power supply); In test 130 W (100 W power supply).

12 V 100 W power supply: The 100 W model reaches about 89% efficiency and pleased the author, though its output rectifier transistor gets very hot.

100 W power supply: A good supply: delivers 130 W at 230 V with normal temperatures and low ripple.
