Internal Power Cable Noctua NA-SAC5

The Noctua NA-SAC5 is a fully sleeved internal power cable that converts a SATA 15-pin power connector to a 4-pin PWM / Molex-style fan power connector. It is intended to power 3-pin and 4-pin fans directly from a power supply’s SATA power outputs, providing a durable black cable solution for internal PC cooling installations.

Advantages

The NA-SAC5 delivers reliable power delivery through a fully sleeved cable and standard SATA 15-pin plug, reducing strain on motherboard fan headers and enabling safe connection of high-wattage fans. Its compatibility with both 3-pin and 4-pin fans and its compact, black design make it straightforward to integrate into most PC builds.

Suitable for

• Powering 3-pin and 4-pin PC fans from a PSU SATA connector
• Connecting high-wattage fans without using motherboard fan headers
• Internal cable routing in desktop PC builds where a SATA power source is available

Key specifications

• Connector 1: SATA 15-pin
• Connector 2: 4-pin PWM (fan power)
• Colour: Black
• Product type: Internal SATA-to-4-pin power adaptor cable
• Manufacturer MPN: NA-SAC5
• EAN: 9010018200263

How to use

Insert the SATA 15-pin plug of the NA-SAC5 into an unused SATA power connector from the power supply, then connect the 4-pin end to the fan’s power socket. Ensure the connectors are oriented correctly and seated firmly. If you need to power multiple fans, pair this cable with compatible Noctua NA-SYC1 Y-cables (sold separately) and verify the total power draw does not exceed the power supply’s SATA rail capability.

Recommendations

Use the NA-SAC5 when you want to avoid loading motherboard fan headers or when you require additional fan power from your PSU; always check fan voltage and combined current draw against PSU specifications and, if needed, use Y-cables designed for high-wattage fans.
