Dell DL90190474 90W Proprietary Adapter
The Dell DL90190474 is a proprietary power adapter rated for 90 watts at 19 volts and 4.74 amps. It also supports 65-watt operation at 19.5 volts and 3.33 amps. The unit accepts AC input from 100 to 240 volts at 50 to 60 hertz. It is designed for HP ProDesk, EliteDesk, Omni, Slimline, Pavilion and select notebook models.
Sustained Load Behaviour
The adapter delivers continuous power through a fixed proprietary connector on a short cable. Its corded electric design maintains stable output during extended desktop or all-in-one workloads. The plastic-jacketed cable and male connector style ensure a secure fit without intermittent contact. No active cooling or fan noise is present.
Deciding Specification
The proprietary connector pair is the single factor that determines compatibility. Only systems listed with the matching proprietary input will work. Buyers needing a standard barrel jack or USB-C power delivery cannot use this adapter.

Questions about this item
Does the 90 W brick run hot or noisy when powering a ProDesk 600 G6 Mini all day?
The adapter delivers up to 90 W at 19 V and 4.74 A with a proprietary connector; it has no fan, so heat is passive and noise is limited to faint coil whine under full load.
What must I already have for this charger to work with my EliteDesk 800 G4 Mini?
You need the matching proprietary DC jack on the Mini and a standard IEC C7 or C5 mains lead for the 100–240 V AC input.
Will the 65 W mode work reliably on an older Omni 120-1134 all-in-one that originally shipped with a 65 W supply?
Yes, the brick auto-switches to 65 W at 19.5 V and 3.33 A, matching the original spec for the Omni 120 series.
