Review conclusionRecommendedNot recommended

Only in one review: Power 500 W (MeanWell EPP-500-54); In test 550 W (MeanWell EPP-500-54); Test current 11.3 A (MeanWell EPP-500-54); Efficiency 95 % (MeanWell EPP-500-54); No load 1.5 W (MeanWell EPP-500-54); Protection 11.3 A (MeanWell EPP-500-54).

MeanWell EPP-500-54: The compact PSU showed high efficiency and acceptable ripple, but the transformer gets noticeably hot under heavy load.

5 V 3 W power supply: It works without overheating, but ripple is high, output current barely reaches its rating, and short-circuit protection behaves oddly; not recommended.

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.
