Only in one review: Voltage 5 V (5 V 40 A power supply (200 W), passive cooling); Power 200 W (5 V 40 A power supply (200 W), passive cooling); In test 207 W (MeanWell LRS-200-12); Under load 4.99 V (5 V 40 A power supply (200 W), passive cooling); Ripple 170 mV (5 V 40 A power supply (200 W), passive cooling); Efficiency 80 % (5 V 40 A power supply (200 W), passive cooling); Protection 43.5 A (5 V 40 A power supply (200 W), passive cooling); Temperature rise 135 °C (5 V 40 A power supply (200 W), passive cooling).

5 V 40 A power supply (200 W), passive cooling: Cannot sustain its rated 200 W: major components overheat at full load, and ripple is high.

MeanWell LRS-200-12: The PSU regulates voltage well and the author clearly recommends it; a long test ran at over 200 W.

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.
