Review conclusion	With reservations	Recommended

Only in one review: Current 4.1 A (48 V 4.1 A, 200 W power supply); In test 160 W (48 V 4.1 A, 200 W power supply); No load 0.75 W (48 V 4.1 A, 200 W power supply); Protection 21.5 A (12 V 200 W power supply).

48 V 4.1 A, 200 W power supply: Well built and handles 4.3 A, but the author puts its sustained power at about 150–160 W.

12 V 200 W power supply: Well designed, with low ripple and little heating; one output diode assembly runs hotter than desirable.
