The single specification that decides fit is the exact part number match. Verify that your existing supply carries one of these six codes before ordering, as other Dell units with different wattages or connectors will not work.

Thermals noise and power draw

Rated at 265 watts maximum output, the unit draws only the power the system components require during normal operation. Standard internal cooling keeps temperatures within design limits for the listed tower chassis, and acoustic output is comparable to the original factory supply.

Questions about this item

How much continuous power does the 265 W rating deliver to a Dell OptiPlex 790 motherboard?

The unit supplies up to 265 watts to the mainboard and drives, matching the factory specification for OptiPlex 390, 790, 990 and Precision T1600 towers.

What connector standard does the supply use to plug into the system board?

It uses the proprietary Dell 24-pin main connector and 4-pin CPU plug found on OptiPlex 3010, 7010, 9010 and Vostro 400 series chassis.

Will this PSU fit a standard micro-tower case such as the Inspiron 560?

Yes, the supply matches the Dell micro-tower form factor used in Inspiron 560, 570, 580 and Precision T1500, so it mounts with the original screws.
