80 PLUS Bronze Efficiency

This PSU is 80 PLUS Bronze certified. It offers efficient power conversion for typical loads. The PRO series targets value-focused users. However, efficiency varies with load and temperature. In practice, it helps manage electricity costs for UK rates. Always check your system’s total wattage needs.

Comprehensive Safety Protections

Safety is prioritised with full suite protections. These include OCP, SCP, OVP, UVP, OTP, and OPP. They safeguard components during normal to extreme power levels. For example, over-voltage protection prevents damage from spikes. Because all capacitors are Taiwanese, build quality is consistent. This ensures long-term reliability for your hardware.
