Features
HELA 1200R Platinum
Cybenetics Platinum 1200W ATX 3.0 & PCIe 5.0 Fully Modular ATX Power Supply
- Equipped with Gen5 12VHPWR PCIe connector, meeting Intel ATX 3.0 specification standard
- Cybenetics Platinum efficiency certification
- 24/7 continuous power output with 50C operating temperature
- Fully Modular design
- All Japanese electrolytic capacitors
- Ultra silent 135mm FDB fan with semi-fanless function
12VHPWR PCIe connector supports ATX 3.0 specifications
The 12+4 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 extended life span

Silent 135mm FDB fan
Built-in 135 mm fan has excellent airflow and low noise, perfect for quiet home or office us

Advanced protections for safety and security
- Over current protection
- Over power protection
- Over voltage protection
- Short circuit protection
- Under voltage protection
- Over temperature protection

This PSU's motherboard connector includes a 6pin sense wire that needs to be connected to the PSU's modular interface as shown. Sense wire helps improve PSU's regulation performance by around 1%-2%.
