Review conclusion	With reservations	With reservations

Only in one review: In test 220 W (Low-profile 12 V 20 A power supply); Efficiency 84 % (Low-profile 12 V 20 A power supply); Protection 14.4 A (24 V 10 A power supply); Temperature rise 100 °C (24 V 10 A power supply); Price 14 $ (24 V 10 A power supply).

24 V 10 A power supply: Neatly built with low ripple, but overcurrent protection trips at about 20 A and there is a serious insulation flaw.

Low-profile 12 V 20 A power supply: It delivers only about 215–220 W versus 240 W rated; build and filtering are poor, though efficiency is 82–84%.
