Review conclusionWith reservationsRecommended

Only in one review: In test 130 W (100-watt power supply); Under load 11.92 V (100-watt power supply); No load 0.65 W (12 V 8.3 A perforated power supply).

12 V 8.3 A perforated power supply: A decent conventional supply overall, though its protection threshold is high and ripple could be lower.

100-watt power supply: A good supply: it handled 11 A at 230 V, with normal temperatures and an output filter.
