Only in one review: Test current 50 A (5 V 40 A power supply (200 W), active cooling); Under load 4.98 V (5 V 40 A power supply (200 W), active cooling); Efficiency 77.5 % (5 V 40 A power supply (200 W), active cooling); Temperature rise 110 °C (HCF-200-12).

5 V 40 A power supply (200 W), active cooling: Handles 200 W with low ripple and reasonable temperatures, but comes with a cheap fan.

HCF-200-12: Generally performs well, but ripple and inductor and shunt heating drew some criticism.
