NuPrime SiGa Power75 Power Supply

NuPrime SiGa Power75, A High-Efficiency Low-Noise DC Power Supply for Audio Systems

The NuPrime SiGa Power75 is a high-efficiency AC-to-DC power supply engineered for precision audio and other low-noise electronic applications. More than a conventional power brick, it converts incoming AC mains into ultra-stable 12V and 5V DC outputs with exceptional efficiency, speed, and noise control. Using an advanced SiC and GaN hybrid design with CM-ANC noise cancellation and RF shielding, it delivers cleaner, faster, and more stable power than conventional adapters and many linear power supplies, making it an ideal upgrade for sensitive DACs, streamers, and digital components. It is available now at Vinyl Sound in Buffalo, NY USA.

Key Features

At its core is a Silicon Carbide (SiC) and Gallium Nitride (GaN) hybrid power architecture, third-generation semiconductor technologies that deliver up to 93% conversion efficiency with fast dynamic response and low switching loss. Common-Mode Active Noise Cancellation (CM-ANC) actively suppresses EMI/RFI across a wide bandwidth up to 1 MHz for a quieter DC supply, while a dedicated bronze isolation shield blocks RF interference and reduces mechanical resonance. High-speed transient performance keeps voltage stable under changing load, and an integrated precision display shows live voltage, current, and wattage with dedicated DIM and ANC controls. It is built for DACs, streamers, network switches, routers, reclockers, and other low-voltage equipment.

Frequently Asked Questions

Q: What can the SiGa Power75 power?
A: The SiGa Power75 provides regulated 12V and 5V DC for low-noise components such as DACs, streamers, network switches, routers, reclockers, and digital processors. It supplies up to 75W total across four 12V (5A) and two 5V (3A) outputs, with the combined load not exceeding 75W.

Q: What connectors and cables does it use?
A: The 12V outputs use DC 5.5 x 2.5mm connectors and the 5V outputs use USB Type-A. For NuPrime devices with 5.5 x 2.1mm inputs, use a 5.5 x 2.5mm to 5.5 x 2.1mm cable (two are included), and for USB-C devices use a USB-A to USB-C cable. Contact Vinyl Sound to confirm the right cable for your gear.

Q: How is this different from a linear power supply?
A: The SiGa Power75 uses a modern SiC and GaN switching architecture with active common-mode noise cancellation and bronze RF shielding, delivering fast transient response and very low ripple (under 1 mVrms with ANC on). NuPrime designed it to offer cleaner, faster, more stable power than conventional adapters and many linear power supplies.

Q: Is the NuPrime SiGa Power75 available in the USA?
A: Yes. The NuPrime SiGa Power75 is available at Vinyl Sound, an authorized NuPrime dealer in Buffalo, NY USA. Contact us for availability and cable compatibility advice.
