Only in one review: No load 0.5 W (100 W, 12 V, 8.3 A power supply in metal case); Weight 850 g (12 V 8.3 A sealed power supply, 850 g).

100 W, 12 V, 8.3 A power supply in metal case: A budget model with sensible cost-cutting, but with concerns about heat, the case, and low-frequency ripple.

12 V 8.3 A sealed power supply, 850 g: A good supply with low ripple and heating, active power-factor correction and higher efficiency, but a relatively high price.
