Integration into a Dell chassis

Builders needing higher wattage for discrete graphics upgrades or non-Dell standard ATX cases cannot use this unit.

Questions about this item

Will the 280W rating hold during long sessions on an Optiplex 755?

The unit is rated for 280W continuous output and is listed as compatible with the Optiplex 755, so sustained loads within that limit are supported.

How much noise or heat does the supply produce when running all day in a GX620?

The 280W design matches the original Dell specification for the GX620, so acoustic and thermal behaviour under normal daily use will be equivalent to the factory unit.
