Power supply unit Thermaltake TR2 S 750W ATX 20+4 pin, 80 PLUS, 120 mm fan, black

Thermaltake TR2 S 750W ATX power supply unit provides up to 750 W continuous output for desktop PCs and compact workstations. Designed to the ATX form factor with standard dimensions (150×140×86 mm), it includes a 20+4 pin ATX connector for motherboard power and an 80 PLUS 230V EU certification for baseline energy efficiency. The unit uses a 120 mm hydraulic bearing fan for cooling, a single high‑amperage +12V rail and a DC‑to‑DC design to stabilise voltages under variable load. Built‑in industrial‑grade protections guard connected components against overcurrent, overvoltage, undervoltage, overpower, short circuit and overheating.

Advantages

The TR2 S 750W combines a compact ATX footprint with a quiet 120 mm hydraulic bearing fan to maintain stable temperatures and low noise during operation. Its DC‑to‑DC topology and single +12V rail ensure consistent voltage regulation and strong amperage for modern CPUs and GPUs. Black, low‑profile cables help with cable routing and airflow management inside the chassis. Industry‑grade protection circuits provide basic hardware safety for continuous use.

Suitable for

• Mid‑range and some high‑end desktop gaming builds
• Home and office workstations requiring stable 12V power
• Compact ATX systems where standard PSU dimensions are needed
• System upgrades replacing older non‑modular ATX power supplies

How to use

Install the PSU into a compatible ATX chassis using the supplied mounting points and secure it with screws. Connect the 20+4 pin ATX cable to the motherboard main power socket and route additional peripheral and PCIe connectors as required for drives and graphics cards. Ensure correct AC mains connection to a suitable power source rated for 220–240 V and switch the unit on after all DC connections are verified. Allow the internal 120 mm fan to establish airflow; normal operation includes low audible fan noise under light to moderate loads.

Recommendations

Use this PSU in systems where total system power consumption remains below the unit’s 750 W rating, maintaining headroom for peak loads. Keep cables tidy and avoid obstructing the fan intake. For sustained high‑power GPU or CPU configurations, verify combined component power draw and consider additional ventilation in the chassis. Regularly inspect connectors and dust filters to ensure optimal cooling and long service life.
