What this adapter powers

This 90-watt RUIQIU AC adapter delivers 19.5 volts at 4.62 amps through a 4.5-by-3-millimetre round tip. It is built for Dell Optiplex micro-form-factor desktops such as the 3000, 3020, 3030, 3040, 3050, 3060, 3070, 3080, 3090, 5000, 5040, 5050, 5060, 5070, 5080, 5090, 7010, 7020, 7040, 7050, 7060, 7070, 7080, 7090, 9010 and 9020 series. It also fits Inspiron laptops and all-in-ones including the 22, 27, 3280, 7700 and 7706 models that require the same tip. The unit accepts 100-to-240-volt input at 50-to-60 hertz for worldwide use.

Check before ordering

Verify that the original charger on your device is rated 90 watts or less; this adapter cannot replace 130-watt, 135-watt, 180-watt or 230-watt units. Confirm the DC connector on your machine is the 4.5-by-3-millimetre round tip, as other Dell systems use larger 7.4-millimetre or USB-C connectors. Ensure the voltage label on your current power supply reads 19.5 volts; a different voltage will not work. The package includes a US two-pin mains cord, so non-US outlets will need a suitable travel adapter.

Who this suits and who should look elsewhere

This adapter suits owners of compatible Optiplex micro desktops and listed Inspiron models who need a 90-watt replacement with over-current, short-circuit and over-charge protection. Buyers whose systems require 130 watts or more, or whose charging port is not the 4.5-by-3-millimetre round tip, should look elsewhere. Users needing a USB-C power delivery source or a higher-wattage brick for workstation-class Dell hardware will not be served by this unit.

Questions about this item

Does the box include a mains cable or just the adapter brick?

The package contains the 90W charger and a US power cord, so no separate mains lead is required.

My Optiplex needs a 65W unit — will this 90W model work safely?

Yes, the 90W adapter is compatible with 19.5V 3.34A 65W and 19.5V 2.31A 45W requirements, but it cannot replace 130W, 135W, 180W or 230W units.

What does the 90W rating mean for daily use on a Micro MFF Optiplex?

It delivers up to 19.5V at 4.62A, providing full power for supported Micro MFF models such as the 7010, 7020, 7040, 7050, 7060, 7070, 7080, 7090, 9010 and 9020.
