Replacement suppliers also identify selected Precision T1700 SFF systems as compatible. Before purchasing, confirm the original Dell DP/N, connector wiring, mounting points and physical dimensions.
This replacement power supply provides a maximum rated output of 255 watts for Dell Small Form Factor systems designed to use the matching PSU configuration.
The wattage is the total output rating and does not guarantee support for additional high-power graphics cards or other hardware upgrades.
Dell's OptiPlex 3020 technical documentation specifies a 255W power supply for the Small Form Factor chassis. Matching replacement units are available within the documented 255W PSU family.
Confirm that the computer is the SFF version, as the OptiPlex 3020 Mini Tower uses a different power supply configuration.
Parts specialists list compatible Dell OptiPlex 7020 Small Form Factor systems for this 255W replacement power supply family.
Check the existing PSU's model number and Dell DP/N before installation to confirm that the replacement matches the computer's original configuration.
The Dell OptiPlex 9020 Small Form Factor is another documented application for matching 255W replacement power supplies.
OptiPlex 9020 Mini Tower and Ultra Small Form Factor systems have different power requirements and should not be assumed to accept the same PSU.
Replacement suppliers also list selected Dell Precision T1700 Small Form Factor workstations within this 255W PSU family.
Confirm the original power supply part number and chassis requirements, as workstation configurations may differ.
The PSU uses an 8-pin main system power connector for the compatible Dell motherboard.
It must not be confused with a standard PCIe graphics power connector or another 8-pin connector with a different electrical pinout.
A separate 4-pin connector supplies power to the processor power input on the compatible motherboard.
Both connectors must match the original PSU's wiring and the computer's system board requirements.
Published replacement specifications identify a 100–240V AC input at 50/60Hz, with a listed rated input current of 4.6A.
Always verify the electrical specifications printed on the actual power supply label, particularly when choosing between different manufacturer revisions.
The power supply is intended for installation inside a compatible Dell SFF desktop chassis, where internal space and mounting arrangements differ from larger Mini Tower systems.
Check the replacement unit's housing dimensions, mounting screw positions, AC inlet orientation and cable reach before purchasing.
Compatible internal PSU assemblies include cooling provisions to help manage heat during normal desktop operation.
Maintain unobstructed airflow and install the power supply in the intended position inside the chassis.
Replacement suppliers list L255AS-00, H255ES-00, D255AS-00, D255E001L, F255ES-00, AC255AS-00, AC255ES-00 and HU255AS-00 among potential compatible PSU models.
These model numbers are cross-reference candidates rather than proof of universal interchangeability. Confirm the exact original Dell part number and electrical specifications.
Parts suppliers identify Dell part numbers including NT1XP, YH9D7, R7PPW, 3XRJ0, V9MVK and FP16X within the compatible 255W SFF power supply family.
Use the Dell DP/N printed on the existing PSU label to help identify the correct replacement.
The OptiPlex 3020, 7020 and 9020 product families include different desktop chassis sizes. The 255W replacement described here is intended for matching Small Form Factor systems.
The Mini Tower versions commonly use a separate 290W PSU family, so the chassis type must be checked before ordering.
A correctly matched 255W power supply can help restore a Dell OptiPlex SFF computer when the original PSU has been diagnosed as defective.
This is useful for offices, educational institutions, computer service centers and IT departments maintaining existing Dell business desktops.
A computer that fails to start or experiences unexpected shutdowns may have a defective PSU, but motherboard faults and other hardware issues can cause similar symptoms.
Professional diagnosis is recommended before purchasing a replacement component.
Disconnect the desktop from AC power before servicing it. Installation should be performed by a technician familiar with Dell power connectors and SFF chassis hardware.
Do not open the PSU housing, modify connector wiring or force incompatible plugs. Internal capacitors can retain hazardous electrical charge after disconnection.
The Dell OptiPlex 3020/7020/9020 SFF 255W Power Supply is suitable for desktop repair technicians, office IT support teams, computer service centers and owners of compatible Dell Small Form Factor desktops. It is especially useful when replacing a diagnosed faulty PSU in an OptiPlex 3020 SFF, 7020 SFF or 9020 SFF system requiring the matching 255W output and 8-pin plus 4-pin power connectors. Selected Precision T1700 SFF workstations may also use this PSU family after exact compatibility verification.
Choose this 255W power supply when your existing Dell desktop uses a matching SFF PSU model or a verified equivalent. Confirm the computer's chassis type, 255W rating, 8-pin motherboard connector, 4-pin CPU connector and AC input specifications. Compare the original Dell DP/N, connector pinout and physical mounting dimensions before ordering. Do not select it for a Mini Tower system based only on the OptiPlex 3020, 7020 or 9020 model name.
Locate the PSU model and Dell DP/N on your original power supply label. Confirm that the computer is an OptiPlex 3020 SFF, 7020 SFF, 9020 SFF or a verified compatible Precision T1700 SFF configuration. Compare the connectors, electrical ratings and mounting points with the replacement unit. If compatibility is uncertain, share clear photographs of the original PSU label and power connections with IT Source Bangladesh. Confirm the exact model, condition, current price and warranty before ordering.
