THERMALTAKE TR2 S 550 550W 80+ White Non Modular ATX 2.0 Power Supply

The Thermaltake TR2 S 550W is a non-modular ATX power supply designed for mainstream desktop PC builds. Built to the Intel ATX 12V 2.3 standard and carrying 80 PLUS 230V White certification, it delivers 82–86% efficiency across 20–100% load, helping reduce energy waste during everyday use and demanding workloads alike. A single +12V rail topology provides stable, consistent power delivery to the CPU, GPU, and other components, eliminating the cross-load instability sometimes seen in multi-rail designs. The unit features Active Power Factor Correction (Active PFC) to improve power quality from the mains supply. Cooling is handled by an embedded 120 mm fan spinning at up to 1800 RPM (±10%), with intelligent RPM control that adjusts fan speed to match thermal load — keeping noise levels in check during lighter workloads. All cables are fully sleeved, allowing neater routing inside your chassis and helping maintain unobstructed airflow. Connectivity includes two PCI-E 6+2-pin connectors, making the unit compatible with a range of discrete graphics cards. The unit accepts a fixed 230 Vac input at up to 7 A, with a frequency range of 50–60 Hz and a hold-up time of 16 ms (minimum) at 60% load. Safety certifications include CE, CB, and TUV approvals. The TR2 S 550W is optimised for use with Intel seventh-generation (Kaby Lake) and compatible processors, and carries a minimum MTBF rating of 100,000 hours.
