Suits owners replacing a failed unit

Buyers needing higher wattage for discrete graphics cards or workstation upgrades should look elsewhere. The fixed 250W output also rules out systems that require redundant or hot-swap power modules.

Verify your Optiplex model is 390.

Confirm the chassis accepts a standard SFF PSU form factor and that the existing connector layout matches the replacement. Check that the 250W rating meets the power budget of your installed components.
