Thermalright TR-SG650 80+ Gold Full Modular Power Supply

About Thermalright TR-SG650

The Thermalright TR-SG650 is a $650\text{W}$ power supply unit (PSU) designed for high efficiency and flexibility, positioning it as an excellent choice for clean, mid-range gaming and workstation builds.Key Features and Efficiency Wattage and Output: It provides a reliable, continuous power output of $650\text{W}$, which is sufficient for many modern systems featuring a mid-to-high-tier graphics card.Efficiency Rating: The unit is 80 PLUS Gold certified, guaranteeing high energy efficiency—typically reaching $90\%$ efficiency at $50\%$ load. This minimizes heat generation and electricity costs.Modern Standards: It is built with current PSU requirements in mind, often adhering to the ATX 3.1 specification and supporting the PCIe 5.1 standard. This ensures the PSU can reliably handle the high, sudden power demands (transient loads) of modern, power-hungry GPUs.Full Modular Design and Build QualityCable Management: The most distinguishing feature of the TR-SG650 (without the 'S' suffix) is its Fully Modular design. This allows users to connect only the cables necessary for their components, greatly simplifying cable management, improving airflow, and resulting in a much cleaner-looking build.Internal Components: Thermalright utilizes high-quality internal circuitry, including LLC Full Bridge and DC-to-DC conversion, to achieve superior voltage regulation ($\pm 3\%$) and ripple suppression across all output rails. Premium components, such as $105^\circ\text{C}$-rated Japanese primary capacitors, are typically used to enhance longevity and stability.Cooling: A quiet $120\text{mm}$ fan (often Hydraulic Bearing) is included, with an intelligent fan control system to manage temperature effectively while maintaining low noise output.Protections: The PSU is equipped with a full set of protection circuits (OVP, OPP, OTP, UVP, OCP, SCP) to safeguard connected hardware from any electrical abnormalities.With its $140\text{mm}$ depth and 5-year warranty, the TR-SG650 combines stability, efficiency, and superior build flexibility.
