Product Description
Genuine Dell H797K, also formatted 0H797K, 255-watt internal power supply for configuration-specific OptiPlex 360/380 desktop systems. Dell's validated OptiPlex 380 list identifies H797K as a 255-watt supply, while exact-part records associate F255E-01 and report a 24-pin main lead, 4-pin 12V lead, two SATA leads, and a floppy lead. Some substitute listings describe 235-watt replacements; those are clues only and do not override the exact 255-watt identification. Power cord, mounting hardware, adapters, and accessories are not assumed included. This inventory record explicitly identifies the condition as New. Match H797K exactly, service tag, system model and DT chassis, complete F255E-01 revision, 255-watt nameplate and rails, dimensions, mounting, every connector, cable length, fan orientation, and pinout before ordering.
