Only in one review: In test 120 W (24 V 100 W power supply); Under load 23.8 V (24 V 100 W power supply); Efficiency 88 % (12 V 8.3 A sealed power supply, 850 g); Protection 9.2 A (12 V 8.3 A sealed power supply, 850 g); Weight 850 g (12 V 8.3 A sealed power supply, 850 g).

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.

24 V 100 W power supply: It runs reliably at 100 W and handled nearly 120 W, though the author notes safety and component-margin concerns.
