80 PLUS Bronze
The efficiency of a power supply directly influences system performance and power consumption.

An 80 PLUS Bronze certified rating means higher efficiency (up to 86%) and reduces internal thermal loading.

120mm Low Noise Fan
A 120mm sleeve bearing fan provides self-regulating cooling, while generating very little noise during operation.

DC-to-DC Circuit Design
A core DC-to-DC circuit design reduces output voltage instability to PC components.

Comprehensive Circuit Protection
A 12V single-rail design delivers stable output currents under heavy loading.

Includes an active PFC design (OCP, OVP, OPP, OTP, SCP protections).

Extensive Connectivity
Connect to multiple hard drives, SSDs, graphics cards and other components with a broad array of cables (non-modular).

Output Specifications
Robust internals support a wide range of AC inputs, while delivering stable output for high performance components.
