Questions about this item

Will the 460 W server power supply need fan or capacitor replacement after long-term use?

Refurbished units are tested before sale; fan bearings and capacitors are the typical wear items to watch during extended operation.

What thermal limit appears first when the 460 W supply runs continuously at full load?

The internal over-temperature protection trips before the output current limit, shutting the unit down until it cools.

How much heat and fan noise does the 460 W power supply produce when the BL460c Gen8 runs all day?

Expect warm exhaust air and audible fan noise proportional to load; the supply draws only the power the server components require.
