Power Adapter Indoor Noctua NV-PS1 90-264V Passive Cooling Black

The Noctua NV-PS1 is a compact 24W AC/DC power adapter with passive cooling designed to power 12V fans and other 12V devices from mains outlets. It supports wide-range AC input (90–264V, 47–63Hz) for compatibility with both 115V and 230V grids and ships with modular EU, US and UK plug connectors. The adapter provides a native 5.5mm OD / 2.1mm ID barrel output and includes an NA-AC10 adaptor cable for connecting 3-pin and 4-pin PWM fans as well as many third-party 12V fans and accessories. With full CE and UKCA compliance, UL and TÜV safety certifications, and built-in protection against overcurrent, overvoltage and short circuits, the NV-PS1 is specified for reliable indoor use and comes with a 6-year manufacturer’s warranty and an MTTF rating of 50,000 hours under full load.

Advantages

The NV-PS1 delivers up to 24W output while maintaining high conversion efficiency and an extremely low idle consumption of 0.075W, making it suitable for both multiple high-speed fans and single low-power fans. Its modular plug set (EU/US/UK) and wide input voltage range ensure global compatibility, and the included NA-AC10 adaptor enables direct connection of Noctua 3-pin and 4-pin fans. The adapter includes comprehensive electrical protections and holds CE/UKCA, UL and TÜV approvals, offering a safe and standards-compliant solution for indoor fan power.

Suitable for

• Powering 12V case or ventilation fans (3-pin and 4-pin PWM)
• Feeding multiple fans via NA-YC1 splitter cables or NA-FH1 / NV-FH2 fan hubs
• Powering single-board computers and other 12V devices that use a 5.5×2.1mm barrel connector

How to use

Attach the appropriate modular mains plug (EU, US or UK) to the adapter and connect the NV-PS1 to a mains outlet. Use the included NA-AC10 adaptor to convert the 5.5×2.1mm barrel connector to a 4-pin Molex-style connector for Noctua 3-pin or 4-pin PWM fans. To power multiple fans, connect NA-YC1 y-cables or a compatible fan hub (NA-FH1 or NV-FH2) to the barrel output. For fan speed control, optionally connect the NA-FC1 controller between the adapter/hub and PWM fans. Ensure the total connected load does not exceed 24W.

Recommendations

Use the NV-PS1 indoors in a dry, ventilated environment and verify combined fan and accessory power draw remains below 24W. For PWM speed control of multiple fans, combine the NV-PS1 with NA-FC1 and suitable splitters or hubs. Follow local electrical regulations and only use the supplied or Noctua-approved cables and adaptors.
