Dell K345R 305W Optiplex 980 MT Power Supply (Renewed)

The Dell K345R is a 305-watt OEM power supply unit engineered specifically for the Dell OptiPlex 980 Mini Tower desktop. It delivers the same wattage and uses the same proprietary connector layout as the original factory-installed PSU, making it a direct drop-in replacement. The unit includes a 24-pin mini ATX motherboard connector, SATA power connectors for storage drives, and a 4-pin floppy power connector, covering all the internal power needs of the OptiPlex 980 MT chassis.

This particular unit is professionally renewed, meaning it has been inspected, tested, and verified to meet Dell's operational specifications before being resold. For users whose original power supply has failed or is showing signs of instability—random shutdowns, failure to boot, or audible coil whine—the K345R provides a straightforward repair path without the risk of aftermarket compatibility issues. It is worth noting that this PSU uses Dell's proprietary form factor and pinout, so it cannot be used in standard ATX cases or non-Dell systems.
