300W proprietary internal power supply for compatible Inspiron 3910 desktops and PowerEdge T150 tower servers requiring the same D12 enclosure and fixed cable configuration. This non-modular PSU includes an 8-pin system-board connector, long 4-pin CPU power connector, and 6+2-pin PCIe graphics-power connector. Grade A refurbished units are cleaned and fully tested.
DPN identifies the 300W platform configuration as Bronze class. Certain manufacturer revisions, including H300EBS-00, have an official 80 PLUS Gold certification; therefore, the efficiency badge may vary on the unit received.

The H300EBS-00 manufacturer label may show the unified reference as D300E020P. D3000E020P is retained above to match the existing CPU Medics item number.
This power supply uses a standard IEC C14 AC inlet. Add the cable below if the original AC power cord is missing, damaged, or not included.
⭐ 5120P - 6FT 125V NEMA 5-15P to IEC C13 Power Cord - Grounded North American AC power cable for connecting the PSU to a standard wall outlet. Sold separately.
Please note that compatibility depends on the system’s original power-supply configuration. Verify the original part number, 300W output, 120mm x 62mm x 185mm enclosure, mounting points, and complete 8-pin + 4-pin + 6+2-pin cable layout before installation.

✓ This is a proprietary D12 cabled power supply, not a standard ATX, SFX, TFX, or Flex ATX replacement.
✓ Confirm the exact 8-pin system-board, 4-pin CPU, and 6+2-pin PCIe connector layout. Do not order based only on wattage or exterior appearance.
✓ This PSU does not use a standard 24-pin ATX motherboard connector.
✓ No SATA power connectors are attached directly to the PSU. Drives receive power through separate system-board-connected drive cables, which are not included unless shown.
✓ Do not confuse this 120mm-wide EBS power supply with narrower 300W EPS models or versions using an 8-pin + 4-pin + 4-pin harness.
✓ The 6+2-pin PCIe connector does not guarantee compatibility with every graphics card. Verify the card’s total power requirement, physical clearance, cooling requirements, and system support.
✓ The AC power cord is not included unless shown. A compatible IEC C13 power cord is available separately above.
✓ Disconnect AC power, press the system power button to discharge residual power, and follow the applicable service procedure before replacing the PSU.
