## Long description

THERMALTAKE TR2 S 550W is an ATX power supply unit engineered for mainstream desktop PCs and small servers. It delivers a total power output of 550 W with AC input 200–240 V, 50 Hz, and uses a 20+4 pin ATX motherboard connector. The unit incorporates a 120 mm hydraulic-bearing fan for active cooling, 80 PLUS 230V EU certification for improved energy efficiency, and a DC-to-DC design with a high-amperage single +12V rail to provide stable voltage regulation under varying loads. Cables are low-profile and black to facilitate neat routing and maintain case airflow, and the PSU includes industry-grade protections for reliable continuous operation.
Advantages
The TR2 S 550W offers balanced performance and efficiency suitable for everyday builds: 80 PLUS 230V EU certification improves energy use, while the DC-to-DC architecture and single +12V rail ensure consistent voltage delivery to components. A 120 mm hydraulic-bearing fan provides effective cooling with low noise. Low-profile black cables support tidy cable management, and built-in protections (over-current, over-voltage, under-voltage, over-power, short-circuit and over-temperature) protect connected hardware.
Suitable for
Mainstream desktop computers with single GPU or integrated graphics
Small home servers and NAS setups that accept ATX power supplies

How to use
Install the TR2 S 550W into a compatible ATX case following the case and motherboard manufacturer guidance. Connect the 20+4 pin ATX main connector to the motherboard, attach SATA and peripheral connectors as required, and connect the AC power cord to a properly grounded mains outlet rated for 200–240 V. Ensure adequate case airflow around the PSU fan intake and verify all connections are secure before powering the system. Observe electrostatic discharge precautions when handling internal components.
Usage recommendations
For stable long-term operation, place the PSU so its fan has unobstructed intake and exhaust paths. Use the TR2 S 550W in systems where total component power draw remains within a safe margin below 550 W to preserve efficiency and thermal headroom. Maintain periodic dust cleaning of the fan and vents and avoid operating the unit in very high ambient temperatures to extend service life.
