Product information

Description

Fully modular design with black flat cables allows installation of only the cables you need to reduce clutter, improve airflow and enhance chassis thermal performance. The unit is 80 Plus Gold certified for high energy efficiency and uses high-quality Japanese main capacitors to ensure stable, efficient operation and extended reliability. A 120 mm smart hydraulic bearing (HYB) fan adjusts speed based on load, stopping at low or idle conditions, while a single +12V rail simplifies power delivery and supports stable output and overclocking. Multiple protection circuits and international safety certifications help ensure system stability under varying conditions. The compact dimensions make the power supply compatible with small chassis.

Advantages

The fully modular black flat cables reduce cable clutter and increase airflow for better thermal performance. 80 Plus Gold certification delivers up to 90% efficiency at typical load, lowering waste heat and fan noise. Japanese main capacitors improve longevity and consistent power delivery. The 120 mm HYB fan provides quieter operation with automatic speed control and stop-at-idle behavior. A single +12V rail offers simple, stable power distribution and better compatibility for high-load scenarios. Built-in protections (OCP, OTP, OVP, OPP, UVP, SCP) and multiple safety certifications increase operational reliability. Compact size fits small form-factor cases.

Key specifications

  • Design: Fully modular with black flat cables
  • Certification: 80 Plus Gold (≈90% efficiency at 50% load)
  • Capacitors: High-quality Japanese main capacitors
  • Cooling: 120 mm smart hydraulic bearing (HYB) fan; fan stops under low/idle load (<20%)
  • Rail: Single +12V rail
  • Protections: OCP, OTP, OVP, OPP, UVP, SCP
  • Compatibility: Compact dimensions for small chassis

How to use

Install only the required modular cables to connect the motherboard, CPU, GPU and peripherals, routing cables to minimize airflow obstruction. Ensure connectors are fully seated and screws are tightened when mounting the power supply into the chassis. The fan is automatic: it adjusts speed according to system load and will stop when load falls below approximately 20%. Verify system stability after first power-up and monitor temperatures under load. Use the single +12V rail connections for high-current devices and follow component manufacturer guidelines for connector placement.

Recommendations

For best results, match the power rating of this fully modular, 80 Plus Gold power supply to your system’s peak load with some headroom, use only the necessary flat cables to preserve airflow, and ensure your case supports the compact dimensions. Regularly inspect cable connections and maintain case ventilation to maximize lifespan and performance.
