About the NuPrime SiGa Power75
The NuPrime SiGa Power75 is a low-noise AC-to-DC power supply with four 12V and two 5V outputs, built on a hybrid of silicon carbide and gallium nitride semiconductors. It is designed to replace standard power adapters for DACs, streamers, network switches, routers and other low-voltage components, with common-mode active noise cancellation and bronze RF shielding. At HiFi Boutique it ships free anywhere in the USA, with sales tax already included.
Why Choose the SiGa Power75
Standard power bricks add switching noise, common-mode interference and RF to the DC line, and recover slowly when the load changes. The SiGa Power75 uses silicon carbide Schottky diodes, which have effectively no reverse-recovery spikes, and GaN switching above 500kHz for fast transient response.
Its CM-ANC circuit actively reduces common-mode noise on the output and load feedback paths, lowering typical 12V ripple from 2.5mVrms to under 1mVrms. A bronze shield blocks RF and reduces interaction between the internal modules.

Who It's For and System Pairing
The SiGa Power75 is for systems where several small components run from wall adapters. With six outputs it can power a streamer, a network switch and a router at once, such as an NuPrime Omnia SW-8 alongside your streaming gear. Check each device's voltage, current and plug size before connecting. Browse the full NuPrime collection to build out your system.
FAQ
FAQ
What outputs does the SiGa Power75 have?
Four 12V outputs rated at 5A and two 5V outputs rated at 3A. Total power across all outputs cannot exceed 75W.
What can I power with it?
NuPrime lists DACs, streamers, network switches, routers, reclockers and digital processors that run on 12V or 5V DC.
