Questions about this item

How often will the internal fan need cleaning or replacement under normal desktop use?

The unit uses a standard ATX cooling fan; dust buildup is the main maintenance, so plan to clean the intake vents every 6 to 12 months and replace the fan only if bearing noise develops.

What thermal or current limit is reached first when the supply runs continuously near its 550 W rating?

Sustained loads close to 550 W will hit the internal over-temperature protection before the 12 V rail hits its current ceiling, causing the unit to throttle or shut down until it cools.
