It provides a 24-pin ATX motherboard connector, a 4-pin ATX +12V CPU power connector, four SATA power outputs, and a legacy floppy drive connector — covering the standard internal power needs of these business-class systems. The unit is a direct form-factor match, making installation straightforward with no adapter brackets or cable modifications required.

As a Certified Refurbished product, this power supply has undergone functionality testing, cleaning, and inspection before repackaging.
