Questions about this item

Does the 290W unit include the 8-pin and 4-pin cables my OptiPlex 3020 motherboard needs?

The PSU comes with both the 8-pin and 4-pin connectors required by the OptiPlex 3020, 7020 and 9020 MT boards.

Will this supply run reliably on the 100-240V 50-60Hz mains in my older workshop?

Yes, the input range is 100-240V at 5.4A covering 50-60Hz, so it works on standard older circuits.

How can I confirm the 290W PSU is delivering power after I install it?

The system will POST and the front power LED stays solid green when the supply is operating correctly.
