Review conclusionWith reservationsNot recommended

Only in one review: Power 150 W (5 V 150 W power supply); In test 150 W (S-120-24).

5 V 150 W power supply: Actual power is about 75% of rating; the inductor and diode assembly overheat at full load.

S-120-24: It delivers the rated 120 W with stable voltage, but build quality and ripple are poor.

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.
