About Thermalright TR-TB850The Thermalright TR-TB850 is an 850W, 80 Plus Bronze certified, and fully modular power supply unit (PSU). It's positioned as a cost-effective solution for PC builders who need a high wattage output without the premium price of a Gold or Platinum-rated unit.Efficiency: The 80 Plus Bronze certification ensures a minimum of 82% efficiency under typical loads (20%, 50%, and 100%), which is a solid level of performance that helps reduce wasted energy and heat compared to unrated PSUs.Modularity: Unlike some other Bronze-rated PSUs that are non-modular or semi-modular, the TR-TB850 features a fully modular design. This is a significant advantage, allowing for clean cable management and improved airflow inside the case by enabling you to connect only the necessary cables.Modern Standards: This PSU is fully compliant with modern standards such as ATX 3.0 and PCIe 5.0. It includes a native 12VHPWR connector, making it compatible with the latest high-power graphics cards without the need for adapters.Cooling: It uses a 120mm fan for cooling. The PSU is designed to operate quietly, and some listings mention a smart fan start-stop feature, which allows the fan to remain off at low loads for silent operation.Safety Protections: The TR-TB850 is equipped with a full suite of safety protections, including OPP (Over Power Protection), OVP (Over Voltage Protection), OTP (Over Temperature Protection), OCP (Over Current Protection), and SCP (Short Circuit Protection), safeguarding your valuable components.Build Quality: Thermalright has included high-quality components, such as 105°C rated Japanese electrolytic capacitors, which are known for their durability and long-term stability. This, combined with a 5-year warranty, demonstrates a commitment to reliability.
