Review conclusionWith reservationsWith reservations

Only in one review: Current 5 A (BP120B-D9-24C); In test 140 W (BP120B-D9-24C); No load 3.5 W (BP120B-D9-24C); Price 110 $ (BP120B-D9-24C).

PTA-120W-12V: A budget PSU with good high-frequency ripple and power headroom, but noticeable low-frequency ripple.

BP120B-D9-24C: It delivers its rated power and holds voltage accurately, but runs hot and is expensive.

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.
