Apexgaming STB-550W

  • Built to deliver 80 PLUS Bronze efficiency, and the application of 120mm silent fan, high quality main capacitor and component. Its reliable and stable output performance provides a safe and reliable power output to your gaming system.

80 PLUS Bronze Certified and
latest Intel 10th gen processors Ready

  • Apexgaming STB-550W saves energy through its high efficiency up to 85% and is certified to 80 PLUS® Bronze.
  • The series has been optimized to work with all generations of Intel’s processors to achieve maximum energy saving.

Apexgaming Silent Tecnology

  • Featuring a temperature sensitive 120mm silent fan to keep friction at really low levels even after prolonged usage while guaranteeing superior cooling performance and silent operation.

Low Ripple Noise

  • The maximum ripple noise is lower than 60mV on the +12V rail, and lower than 40mV on the +5V &+3.3V rails to ensure an excellent power supply stability. Low ripple noise will keep your performance-critical components, such as high-end graphics cards, to operate reliably for longer.

<±3% Strict Voltage Regulation

  • The voltage regulation of the PSU is set to no more than ±3% for major output rails to meet the highest performance. The strict voltage regulation is better than Intel’s ATX standard ±5% for major rails and ±10% for -12V.

Steady Power Supply Design

  • STB-550W has been implemented power supply design by Active PFC and Dual Forward. This steady power supply design scheme can improve power quality and reliability, and can also provide stable power output.

Powerful single +12V rail design

  • STB-550W has powerful single +12V rail, intelligent distribution of power requirements, support most game graphics cards.

Nylon-braided Cables

  • Easier for installation and full protect the cables also improve the better airflow.
