4-Pin Molex to Floppy Drive Power Adapter Cable (20cm / 8"), LP4 IDE Male to 4-Pin Mini-Molex FDD Female 18AWG Power Converter for PC Floppy Drives & PCIe Cards

Bridge modern or legacy PC power supplies with vintage drives and internal expansion peripherals using this 4-Pin Molex to Floppy Drive Power Adapter Cable (20cm / 8"). As modern ATX power supply units (PSUs) increasingly omit native floppy power connectors, this handy converter bridges a standard 4-pin LP4 Molex male peripheral plug to a 4-pin Mini-Molex (Berg/FDD) female connector. Built with heavy-duty 18AWG pure copper wiring, it delivers steady 12V and 5V DC power to internal 3.5-inch floppy drives, multi-card readers, and add-in PCIe controller cards.

• Standard LP4 to Mini-Molex FDD Conversion: Converts a standard large 4-pin IDE/Molex power connector from your power supply into a small 4-pin floppy drive power plug, providing essential power without upgrading your entire PSU.
• Heavy-Duty 18AWG Pure Copper Wire: Constructed with industry-standard 18 AWG multi-strand pure copper conductors. Easily handles continuous electrical draw without voltage drops, resistance heating, or insulation melting under heavy loads.
• Full 4-Wire Standard ATX Voltage Mapping: Fully mapped with standard PC power color codes: Yellow (+12V), Red (+5V), and dual Black (Grounds). Ensures 100% correct polarity and voltage regulation for sensitive legacy hardware.
• Firm & Secure Latching Connectors: Both ends are precision-molded from high-density flame-retardant nylon. Features a firm friction-fit Molex housing and a latching Berg connector to prevent accidental disconnections during internal case cable routing.
• Optimal 20cm (8") Cable Length: Provides 8 inches of flexible wiring, giving you the perfect slack to bridge drive bays and power cable harnesses without generating unsightly wire nests inside your chassis.
• Versatile Equipment Compatibility: An indispensable power lead for internal 3.5" floppy disk drives (1.44MB/720KB), 3.5" front-panel USB card readers, PCIe USB 3.0 expansion cards requiring supplemental power, and specialized internal sound cards.
