Review conclusionRecommendedRecommended

Only in one review: In test 85 W (TMP-30124C); Test current 3.5 A (12 V 3 A desktop power supply); Ripple 300 mV (TMP-30124C); Efficiency 85 % (TMP-30124C); No load 2 W (TMP-30124C).

12 V 3 A desktop power supply: Nearly identical to the adapter version: temperatures are normal and protection trips around 3.4–3.5 A.

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.
