Thermalright TR-SG-850 ATX 3.1 850W Plus Gold PSU

Thermalright TR-SG-850 is an 850W modular ATX power supply with 80+ Gold efficiency, aimed at mid-range to high-end gaming and workstation configurations. Thanks to support for ATX 3.0/3.1 and PCIe Gen 5.0/5.1, it is fully ready for modern graphics cards, including those with the new 12VHPWR connector. The active PFC, 87% efficiency, and quality Japanese capacitors make the power supply more stable and less hot under load. The black design without RGB makes it suitable for simple, clean cases.

What you get: With a power of 850W, you have enough resources for a strong CPU and modern high-end GPU, without the power supply struggling under peak loads. The full modular design allows you to use only the necessary cables, which simplifies cable management and improves airflow in the case. The PCI-E Gen5 12VHPWR connector provides a direct and secure connection to new graphics cards, without the need for adapters. The 120 mm intelligent Start-Stop fan reduces noise in idle or light load, as it can stop completely and only turns on when actual cooling is needed. The internal DC-DC LLC Half-Bridge structure and 105°C Japanese capacitors aim for better voltage stability and longer life under continuous operation.

• Power 850W – sufficient for serious gaming and workstation systems with a powerful CPU and high-class GPU.
• 80+ Gold, efficiency 87% – less heat loss and more stable operation under load compared to basic Bronze solutions.
• ATX 3.0/3.1 and PCIe Gen 5.0/5.1 – the power supply is compatible with new standards and is ready for future graphics cards and components.
• PCI-E Gen5 12VHPWR x 1 – direct power to modern GPUs without adapters, with a cleaner and safer cable path.
• Full modular design – all cables are detachable, which simplifies assembly and improves internal airflow.
• 120 mm intelligent Start-Stop fan – quieter operation under low load, as the fan only turns on when needed.
• 105°C Japanese capacitors and DC-DC LLC Half-Bridge structure – better stability of the 3.3/5/±12 V lines and higher reliability over time.
• Rich set of connectors – 20+4 Pin ATX, 4+4 Pin ATX/EPS x 2, PCI-Express 6+2 pin x 4, SATA x 8, and Molex x 3 cover a typical configuration with plenty of storage and peripherals.

Who it is suitable for: If you are building a mid-range or high-end gaming/creator machine with the option for a serious GPU upgrade in the future, this power supply is a very good core for your system. It is also suitable for quiet builds where you want the fan to be silent under light load. It is not necessary for completely budget or office configurations, where even 500–600W would be sufficient.

The most sensible thing here is the combination of 850W power, ATX 3.1 + 12VHPWR, and full modular design – you get a power supply that is both ready for new graphics cards and convenient for a clean, organized build.
