Questions about this item

Will the 280 W unit need its internal fan replaced after long-term use?

The fan is a sealed component; replacement is not user-serviceable and would require a full supply swap.

What limit appears first when the PSU runs continuously at full load?

The 280 W rating is the hard ceiling; sustained draw above that triggers over-current protection and shuts the unit down.
