Questions about this item

How much noise and heat does the 240 W unit produce when running continuously?

The supply is rated at 240 W output; typical server PSUs of this class use a temperature-controlled fan that ramps up under load, so expect moderate airflow and audible fan noise during sustained operation.

Which existing cables or components must I already have to install this PSU in a Dell OptiPlex SFF?

You need the Dell OptiPlex 390, 790, 990, 3010, 7010 or 9010 Small Form Factor chassis; the unit provides 1x 24-pin ATX, 1x 4-pin ATX, 2x SATA and 1x 2-pin Slimline SATA connectors.

Will this replacement PSU work alongside the original motherboard and drives in an OptiPlex 790 SFF?

Yes, it matches Dell part numbers CCCVC, RV1C4, 3WN11, J50TW, 2TXYM, 709MT, 592JG, 66VFV, 3YKG5 and PH3C2 for those systems.
