Virtalähde Thermaltake TR2 S 650W – ATX, 20+4-pin, 80 PLUS, 120 mm tuuletin, musta

Thermaltake TR2 S 650W is an ATX power supply unit designed for desktop PCs and entry-level servers requiring stable single-rail power delivery. Delivering 650 W of total output and equipped with a 20+4 pin ATX motherboard connector, this PSU supports 200–240 V AC at 50 Hz and carries 80 PLUS 230V EU (80 PLUS) efficiency certification. The unit uses a DC-to-DC design with a high-amperage single +12V rail to provide consistent voltage regulation and reliable continuous operation. A 120 mm hydraulic bearing fan provides active cooling while maintaining low noise, and low-profile black cables facilitate tidy cable routing to preserve airflow.

Advantages

High-amperage single +12V rail and DC-to-DC circuitry improve voltage stability under varying loads, reducing the risk of system instability. The 80 PLUS 230V EU certification ensures baseline energy efficiency around 80%, helping to reduce wasted power in compatible regions. An industrial-grade protection suite (over-current, over-voltage, under-voltage, over-power, short-circuit and over-temperature protections) protects connected components. The hydraulic bearing 120 mm fan balances cooling performance and low acoustic output for quieter operation in everyday use.

Suitable for

• Home and office desktop computers with mainstream components
• Small form ATX builds requiring a single reliable +12V rail
• System upgrades where 650 W total power and standard ATX connectivity are sufficient
• Setups that benefit from quieter cooling and tidy cable management

How to use

Install the PSU into a compatible ATX chassis aligned with the case mounting points and connect the 20+4 pin ATX cable to the motherboard. Attach required peripheral connectors such as SATA power cables to drives and any additional PCIe or CPU connectors provided by the unit according to your system configuration. Ensure the input voltage selector (if present) and mains wiring match local 200–240 V AC supply and power on the system. Verify stable boot and monitor voltages under initial load to confirm correct installation.

Recommendations

For reliable operation, maintain adequate case airflow and avoid routing cables across intake or exhaust paths. Use this 650 W unit in systems whose combined component draw remains within the PSU’s rated output with headroom for peak loads. Periodically check for dust buildup on the fan and vents and clean as needed to preserve cooling efficiency and acoustic performance.
