Genuine Dell MH495 305-watt internal desktop power supply associated by exact-part records with N305N-03/NPS-305FB D and configuration-specific Dimension E520/E521 and OptiPlex mini-tower systems. Detailed supplier data reports a 24-pin ATX main lead, 4-pin 12V lead, four SATA leads, floppy power, and an approximately 150 x 98 x 140 mm chassis. Broad compatibility and replacement-number lists are treated only as clues because OEM revision, chassis, harness, and pinout can differ. Power cord, mounting hardware, adapters, and accessories are not assumed included. This inventory record explicitly identifies the condition as New.
