The Dell H275P-01 is a 275W internal power supply used in selected Dell OptiPlex Small Form Factor desktops, including the 740, 745 and 755 series. Replacement specifications identify a 24-pin ATX motherboard connector, a 4-pin CPU connector, SATA power and additional optical-drive connections. The PSU accepts 100–127V AC at 6A or 200–240V AC at 3A, with a published 47–63Hz input frequency. Its approximate dimensions are 210 × 82 × 62mm. Common Dell part number references include PW124, RM117, FR619 and WU142. Confirm the original PSU label, connector configuration and chassis compatibility before installation.
The H275P-01 provides a maximum rated DC output of 275 watts for compatible Dell desktop computers. It is intended to replace a matching original PSU when the existing unit has failed.
The 275W rating describes the maximum combined output. It does not automatically support additional high-power graphics cards or hardware upgrades.
Replacement-parts suppliers identify selected Dell OptiPlex 740 Small Form Factor configurations as compatible with the H275P-01 PSU.
Check the original part number and physical enclosure because other OptiPlex 740 chassis sizes may use different power supplies.
The Dell OptiPlex 745 Small Form Factor is a documented application for the H275P-01 replacement power supply family.
Verify the existing unit's Dell DP/N, connector arrangement and mounting points before ordering.
Parts specialists also list the H275P-01 for compatible Dell OptiPlex 755 Small Form Factor desktops.
Matching the original PSU model and chassis configuration is important because other OptiPlex 755 variants may require different power supplies.
Replacement suppliers also identify selected OptiPlex GX520 and GX620 SFF, Dell Dimension 5100c, 5150c and 9200C, and Dell XPS 210 systems as compatible applications.
These are supplier-listed compatibility references, not a guarantee that every configuration uses the same PSU.
The H275P-01 includes a 24-pin main motherboard power connector for compatible Dell system boards.
Confirm that the original motherboard uses the same connection and wiring arrangement before installation.
A separate 4-pin ATX +12V connector supplies power to the compatible processor power input on the motherboard.
This connector is different from small 4-pin optical or peripheral power connectors and must be connected to the correct socket.
The documented configuration includes a SATA power connector for compatible internal storage devices.
Confirm that the connector position and cable length suit the original computer's drive installation.
Some H275P-01 revisions include a slimline SATA power connector and an additional 4-pin optical-drive power connector.
Parts specialists note that PSU revisions differ, particularly in the availability of the slimline SATA connection. Compare the actual unit with the original power supply.
Published specifications list 100–127V AC at 6A and 200–240V AC at 3A, with a 47–63Hz input frequency.
Verify the electrical rating printed on the exact PSU label before installation, especially when purchasing a replacement with a different manufacturer revision.
Replacement specifications list +12V at 17A, +5V at 18A, +3.3V at 5A, -12V at 0.5A and +5V standby-related output at 4A.
All rail ratings are subject to the PSU's combined 275W output limit and any additional rail-specific limits printed on the label.
The H275P-01 uses an elongated internal housing measuring approximately 210 × 82 × 62mm, as listed by specialist replacement suppliers.
Confirm the housing dimensions, mounting screw locations, AC inlet orientation and cable reach before purchasing.
The power supply uses an internal fan to help remove heat produced during normal operation.
Maintain clear airflow around the PSU and install it in the intended position inside the Dell desktop chassis.
Parts suppliers associate the H275P-01 replacement family with Dell part numbers PW124, RM117, FR619 and WU142.
Check the Dell DP/N on the original PSU label because part numbers can help distinguish physically similar units and connector revisions.
Replacement catalogs also reference D275P-00, L275E-01, N275P-01 and H275E-00 within the same 275W Dell PSU replacement family.
These are potential cross-references only. Confirm the original Dell part number, electrical pinout, storage connectors and mounting dimensions before treating another model as interchangeable.
A properly matched H275P-01 can help restore an older Dell business desktop after the original power supply has been diagnosed as defective.
This makes it relevant for offices, repair workshops, educational institutions and organizations maintaining compatible legacy desktop systems.
A computer that fails to start or experiences unexpected shutdowns may have a faulty PSU, but similar symptoms can result from other hardware problems.
Have the system properly diagnosed before purchasing a replacement component.
Disconnect the desktop from AC power before replacing the PSU. Installation should be performed by a technician familiar with Dell desktop hardware.
Never open the PSU enclosure, modify power wiring or force incompatible connectors. Internal capacitors can retain dangerous electrical charge even after the power cable has been disconnected.
The Dell H275P-01 275W Power Supply is suitable for desktop repair technicians, office IT support teams, computer maintenance departments and owners of compatible Dell OptiPlex Small Form Factor systems. It is especially relevant when replacing a diagnosed faulty PSU in an OptiPlex 740 SFF, 745 SFF or 755 SFF computer requiring the matching 24-pin motherboard and 4-pin CPU power connections. Selected older OptiPlex GX, Dimension and XPS desktop configurations may also use this PSU family, provided the original Dell part number, storage connectors and mounting arrangement match.
Choose the Dell H275P-01 when your existing computer uses this exact PSU model or a verified equivalent. Confirm the 275W output, 24-pin ATX motherboard connector, 4-pin CPU connector, AC input ratings and approximate 210 × 82 × 62mm housing. Check whether the original unit uses a slimline SATA power connector, because replacement revisions can differ. Match the Dell DP/N and physical mounting requirements before ordering.
Read the model number and Dell DP/N printed on your original power supply. Confirm the computer's exact model and Small Form Factor chassis, then compare the motherboard, CPU and storage power connectors. Check the electrical ratings, housing dimensions and mounting points.
