Review conclusionWith reservationsWith reservations

Only in one review: In test 250 W (WX-DC2440); Under load 12.216 V (CTG-300W-12V); Efficiency 85.5 % (WX-DC2440); No load 4 W (WX-DC2440); Protection 14 A (WX-DC2440); Temperature rise 105 °C (CTG-300W-12V); Weight 377 g (WX-DC2440).

CTG-300W-12V: It is effectively suited to about 230–250 W; the small input capacitor and higher ripple detract from it.

WX-DC2440: The PSU performs fairly well up to 240 W but overheats; modifications and a fan are advised for sustained use.

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.
