Thermalright TR-SG650S 80+ Gold Power Supply

About Thermalright TR-SG650S

The Thermalright TR SG-650S Power Supply is a 650-watt unit designed to offer an excellent balance of efficiency, reliability, and modern standards for mid-range gaming and enthusiast PCs.Key Specifications and Efficiency ⚡Wattage: $650\text{W}$ continuous power output, suitable for powering most single mid-to-high-tier GPU setups.Efficiency: It holds an 80 PLUS Gold certification, meaning it achieves up to $90\%$ efficiency under typical load conditions. This results in reduced heat generation, lower energy consumption, and quieter operation compared to Bronze-rated units.Form Factor: Standard ATX size, with dimensions typically around $L150 \text{mm} \times W140 \text{mm} \times H86 \text{mm}$.ATX Standard: Often compliant with the modern ATX 3.1 specification, which is important for handling the transient power spikes (power excursions) of modern graphics cards.Design and ProtectionCable Management: The SG-650S model is usually non-modular (fixed cables). This makes it a budget-friendly option, though it requires more careful cable routing inside a PC case. Thermalright also offers fully modular variants in the SG series, such as the SG-650.Internal Circuitry: It utilizes advanced topologies like LLC Full Bridge and DC-to-DC modules to ensure exceptional voltage regulation and power stability across all rails, especially the crucial $+12\text{V}$ rail.Cooling: A $120\text{mm}$ fan is used to maintain optimal operating temperatures. The fan is typically designed for quiet operation.Protections: The unit includes a comprehensive suite of safety mechanisms to protect the PC components, including Over Power Protection (OPP), Over Voltage Protection (OVP), Over Temperature Protection (OTP), Over Current Protection (OCP), Short Circuit Protection (SCP), and Under Voltage Protection (UVP).The TR SG-650S is a reliable and highly efficient choice for users building a new PC or upgrading an existing system, prioritizing stability and power quality.
