Questions about this item
Will the internal fan need replacement on the 550W unit?
The fan is a serviceable part; under normal server duty it typically runs for years before bearing wear requires a swap.
What limits sustained output on the 550W supply first?
Thermal protection engages before the 550W rating is exceeded, so continuous load is capped by cooling capacity rather than electrical headroom.
