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

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.

Weather-resistant 100 W 8.3 A: Neat enclosure and protection, but limit load to 75–80 W at elevated ambient temperatures; ripple is high.
