Know before you buy
This power supply is designed to improve the performance of sensitive internal PC components that rely on 5V power, such as JCAT USB and Ethernet cards, as well as SSDs. By cleaning the power feed, it helps these components operate with less electrical noise.
Standard PC power supplies are designed for general operation and often introduce electrical noise. The OPTIMO nano acts as an active filter and buffer, utilizing four LT3045 linear regulators to deliver a stable, ultra-low-noise 5V output specifically tuned for high-fidelity audio applications.
The OPTIMO nano is designed for internal PC installation and is relatively straightforward if you are comfortable opening your computer case. It is a plug-and-play device that connects using the included LP4 Molex and SATA cables.
The OPTIMO nano provides a maximum output current of 2.0A, which is sufficient for most audiophile-grade USB cards, network interface cards, and SSDs. It is important to verify that your specific components do not exceed this 10W total power limit.
The unit is built with multiple protection mechanisms to ensure safe operation within your computer. These features are designed to prevent damage to both the power supply and the connected components in the event of an electrical fault.
