Dell MK9GY 305W OptiPlex 780 MT Power Supply

Genuine Dell MK9GY 305-WATT internal power supply validated by Dell for configuration-specific OptiPlex 780 mini-tower systems. Government catalog data identifies it as a HiPro 305-WATT mini-tower supply with active power-factor correction. PF3TR, P192M, M360M, CY827, and other Dell 305-WATT family numbers remain identification clues only because OEM source, connector size, cable layout, rail capacity, and pinout can differ. Power cord, mounting hardware, adapters, and accessories are not assumed included. This inventory record explicitly identifies the condition as New. Match MK9GY exactly, Dell service tag, system model and MT chassis, complete HiPro model/revision, 305-WATT nameplate and rails, active-PFC marking, dimensions, mounting, every connector, cable length, switch, fan orientation, and pinout before ordering.
