This brand-new 255W small form factor power supply model H255ES-00 (YH9D7) is an exact OEM replacement for Dell Optiplex 3020, 7020, 9020 and Precision T1700 SFF desktop systems. It perfectly fits Dell spare part numbers R7PPW, 3XRJ0, V9MVK, FP16X, T4GWM, M9GW7 and FN3MN.
Constructed with premium stable internal electronic components, this compact SFF PSU outputs low-ripple steady clean power to fully safeguard motherboard, CPU, RAM and storage hardware under daily multitasking office loads. Built-in intelligent safety circuits automatically cut off power supply once abnormal voltage, overload or overheating is detected to prevent permanent hardware burnout.
Equipped with a silent optimized cooling fan and mini heat sink structure, it rapidly exhausts internal heat inside narrow SFF chassis while maintaining quiet running noise suitable for office environments. All power cable interfaces and installation dimensions strictly comply with Dell factory specifications, requiring no wiring modification or extra adapters for fast installation. Every unit undergoes rigorous aging, voltage stability and safety testing before shipment, meeting OEM reliability standards for enterprise PC maintenance and defective SFF power supply replacement.
