Review conclusionNot recommendedRecommended

Only in one review: Current 4.2 A (Sanmim GPA50A-12); Test current 8 A (Sanmim GPA50A-12); Under load 11.95 V (Sanmim GPA50A-12); Ripple 55 mV (Sanmim GPA50A-12); Temperature rise 128 °C (Sanmim GPA50A-12).

12 V 50 W power supply: It failed during testing at 115 V; protection is set too high and output capacitance is insufficient.

Sanmim GPA50A-12: The PSU substantially exceeded its rated current and showed low ripple; the author recommends buying it.

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.
