Review conclusionRecommendedRecommended

Only in one review: In test 85 W (TMP-30124C); Test current 3.2 A (12 V 3 A power supply, adapter); Efficiency 85 % (TMP-30124C); No load 2 W (TMP-30124C).

12 V 3 A power supply, adapter: After the revisions it runs without overheating even at 3.2 A, with acceptable ripple and electrical safety.

TMP-30124C: An excellent supply that handles overloads well and keeps ripple within spec; drawbacks are high idle draw and a fuse the author could not find.
