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 87.5 % (Sealed 100 W, 12 V, 8.3 A power supply); No load 0.5 W (Sealed 100 W, 12 V, 8.3 A power supply); Protection 11.5 A (Sealed 100 W, 12 V, 8.3 A power supply).

Sealed 100 W, 12 V, 8.3 A power supply: Heat and stability are good, but ripple reaches 800 mV at maximum load.

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.
