Review conclusion	With reservations	With reservations

Only in one review: In test 220 W (Low-profile 12 V 20 A power supply); Test current 18.1 A (Low-profile 12 V 20 A power supply); No load 0.1 W (24 V 8–10 A power supply); Temperature rise 70 °C (24 V 8–10 A power supply).

24 V 8–10 A power supply: Usable with reservations: without forced cooling it sustains only 150–160 W, and ripple is high.

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%.
