12VHPWR PCIe connector supports ATX 3.0 and PCIe Gen5 standards

The 16 pin (12VHPWR) design is capable of withstanding power failure caused by a running graphics card’s instantaneous peak power consumption, whilst providing higher stability and efficiency power output for high-end systems.


Cybenetics Platinum Certified

Designed for Cybenetics Platinum level of efficiency to reduce wasted heat and save on electricity.

Fully modular design with universal EPS / PCIe connector interface

Flat cables have much greater flexibility to allow for tighter folding and management of cable.

All Japanese electrolytic capacitors

Ensure reliable power and long-life span.

Silent 135mm FDB fan

Built-in 135 mm fan has excellent airflow and low noise, perfect for quiet home or office use.
