Thermalright TR-SG750S 80+ Gold Power Supply

About Thermalright TR-SG750S

The Thermalright TR-SG750S is a $750\text{W}$ power supply unit (PSU) from the SG series, designed to provide efficient and reliable power for mid-to-high-end gaming PCs and workstations.Key Specifications and Efficiency Wattage: It delivers a continuous power output of $750\text{W}$, which is ample headroom for most modern CPUs and high-performance graphics cards, including some higher-tier models.Efficiency: The unit is 80 PLUS Gold certified, ensuring a high level of energy efficiency—up to $90\%$ under typical load. This reduces electricity costs and minimizes wasted energy as heat, contributing to the system's overall cooling.Modern Standards: The TR-SG750S is often compliant with the modern ATX 3.1 standard and includes support for PCIe 5.1, which is crucial for handling the significant transient power spikes of contemporary GPUs.Design and Build QualityCable Management: The "S" suffix typically denotes a Non-Modular (fixed cable) design, which makes the unit more budget-friendly, though it may require more effort for clean cable management. (Note: Thermalright also offers a fully modular SG-750 model without the "S".)Internal Circuitry: It uses advanced internal topologies such as LLC Full Bridge and DC-to-DC conversion to provide tightly regulated voltages and stable power delivery, particularly on the critical $+12\text{V}$ rail.Cooling: It is equipped with a $120\text{mm}$ fan (often Hydraulic Bearing) with an optimized curve to ensure effective cooling while keeping noise levels low. Some versions may feature a smart fan start/stop function for silent operation under low loads.Protections: The PSU comes with a full suite of protection features, including OPP, OVP, OTP, OCP, SCP, and UVP, guaranteeing the safety of your connected components against electrical faults.With a compact $140\text{mm}$ depth and a 5-year warranty, the TR-SG750S offers performance and peace of mind for enthusiast builds.
