Product information

Description

The Thermalright KG-650 Fully-Modular ATX Power Supply Unit provides a reliable 650 W power output designed for modern desktop systems and All-in-One PCs. Featuring an 80 PLUS Gold certification, this power supply unit ensures high energy efficiency, reducing power loss and heat generation during operation. Its fully-modular cabling design allows users to connect only the necessary cables, improving cable management and airflow inside the computer case. Operating on a universal AC input voltage range of 100 to 240 V, it adapts seamlessly to various electrical standards.

Advantages

This power supply unit utilizes an advanced LLC resonance and DC-DC circuit design paired with Japanese main capacitors rated for 105°C temperature resistance, contributing to extended component lifespan and stable power delivery. The inclusion of multiple protection circuits safeguards connected hardware against potential electrical anomalies. A quiet 12 cm cooling fan maintains optimal thermal performance under load. Furthermore, the unit is fully compatible with the Intel ATX 3.1 specification, supporting up to 200% power excursion to handle sudden load spikes efficiently.

Suitable for

  • Building or upgrading standard desktop computers
  • All-in-One PC systems requiring an ATX form factor
  • Gaming and productivity setups demanding stable 650 W power
  • Systems benefiting from clean cable management with fully-modular cabling

This power supply may not be suitable for extreme enthusiast builds equipped with multiple high-power graphics cards or high-end workstation processors that consistently require a total power output significantly exceeding 650 watts under full load.

Key specifications

  • Total power: 650 W
  • 80 PLUS certification: 80 PLUS Gold
  • Form factor: ATX
  • Cabling type: Fully-Modular
  • Cooling fan diameter: 12 cm
  • Motherboard power connector: 20+4 pin ATX
  • AC input voltage: 100 - 240 V
  • Included cables: CPU, PCIe, SATA, PATA

Installation requires mounting the unit inside a compatible ATX computer case using standard screws and connecting the required fully-modular cables to the motherboard, graphics card, storage drives, and other system components. Ensure the power switch is in the off position and the unit is disconnected from the wall outlet before installing or changing any internal connections.

What to consider before purchase

  • Verify that the 650 W power capacity is sufficient for your specific hardware components
  • Check your computer case dimensions to ensure physical compatibility with the ATX form factor
  • Confirm the availability of required connectors such as PCIe and SATA for your specific devices
Usage recommendations: To ensure longevity and safe operation, keep the computer case ventilation areas unobstructed and avoid operating the power supply unit in environments with excessive moisture or extreme temperatures. Regularly check internal cable connections during routine system maintenance.
