Review conclusionWith reservationsWith reservations

Only in one review: Test current 7.3 A (120-watt power supply); 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.

120-watt power supply: Decent as an 80–85 W supply at 230 V, but it does not deliver the claimed 120 W and has higher 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.
