DMKAOLLK 65W 45W AC Adapter 4.5x3.0mm 3-Prong for Dell OptiPlex Micro Desktop

SKU CH-3KHK-8658T

A 65W AC adapter with a 4.5x3.0mm 3-prong connector for Dell OptiPlex Micro desktops and select Inspiron laptops

  • Delivers up to 65W at 19.5V 3.34A for OptiPlex Micro desktops
  • Also powers 45W systems at 19.5V 2.31A with the same adapter
  • 5×3.0 mm three-prong connector fits listed Dell OptiPlex and Inspiron models
  • Built-in overload, over-voltage and short-circuit protection safeguards connected hardware
  • Accepts 100-240V AC input for worldwide use without a voltage converter

Replacement power for OptiPlex Micro desktops

This 65 W AC adapter supplies 19.5 V at 3.34 A and is also compatible with 45 W 19.5 V 2.31 A requirements. It fits Dell OptiPlex 9010, 9020, 7040, 7050, 7060, 7070, 3020, 3040, 3050, 3060, 3070, 5050, 5060, 5070 and D-series Micro models. The 4.5 mm by 3.0 mm three-prong connector matches the factory jack on these systems.

Wide-range input with built-in protection

The unit accepts AC 100-240 V at 1.6 A across 50-60 Hz, so it operates on mains supplies worldwide without a voltage switch. Overload, over-voltage and short-circuit protection circuits are integrated to guard the adapter and the connected desktop. No fan is present, so operation is silent in normal use.

Bundled mains cord and optional converter

Each package includes one AC adapter and one AC power cord ready for immediate connection. A converter cable is supplied for situations where a similar-looking 7.4 mm by 5.0 mm Dell jack is encountered, though the primary 4.5 mm by 3.0 mm plug covers the listed OptiPlex and Inspiron models. Buyers needing a different connector size or a higher wattage rating should verify their device specification before ordering.

Questions about this item

How do I connect the 4.5x3.0mm 3-prong plug to my OptiPlex Micro desktop?

Align the 4.5 mm outer and 3.0 mm inner diameters with the DC jack, push the 3-prong connector straight in until it seats firmly, then plug the IEC C13 cord into a 100-240 V outlet.

Which parts of this adapter wear out first and need replacement?

The IEC power cord and the 19.5 V DC cable see repeated flexing; the internal overload, over-voltage and short-circuit protection components may degrade after years of 65 W or 45 W loads.

At what point does the 65 W output limit throttle my Micro desktop under sustained load?

When the system draws more than 3.34 A at 19.5 V, the built-in overload protection engages and reduces power, so sustained peaks above 65 W will be capped.
