Power supply Thermalright TR-KG850 PSU ATX 3.1 850W Gold, Full Modular

Thermalright TR-KG850 is a 850W ATX power supply with 80+ Gold certification and a fully modular design, aimed at mid-range to high-end gaming and workstation configurations. It supports ATX 3.0/3.1 and PCIe Gen 5.0/5.1, meaning it is ready for modern GPUs with the new connector standard. The black design without RGB is for those looking for a clean, functional build without unnecessary lights. Overall – the focus is on efficiency, stability, and easy cable management.

What you get

With a power of 850W, you have enough headroom for modern multi-core CPUs and a serious GPU, without worrying about shortages under load. The 80+ Gold certification and declared 90% efficiency mean less heat loss and lower power consumption at the same load. The fully modular design allows you to connect only the necessary cables, which helps for better airflow and easier cable management. Support for ATX 3.0/3.1 and PCIe Gen 5.0/5.1, plus the presence of a PCI-E 5.1 connector, ensures direct compatibility with the new generation of graphics cards, without adapters. A 120mm fan takes care of cooling, while active PFC helps for more stable operation under varying power supply voltages in the range of 100 - 240 VAC.

• Power 850W – sufficient for strong gaming and creative configurations with one high-end GPU and many storage devices.
• 80+ Gold certification and around 90% efficiency – less loss, lower consumption at the same load, and less heat generated in the case.
• ATX 3.0/3.1 with PCIe Gen 5.0/5.1 and PCI-E 5.1 connector – readiness for modern graphics cards with the new power standard, without the need for additional adapters.
• Full modularity – you can connect only the necessary cables, making installation easier and keeping the inside of the case more organized and well-ventilated.
• Rich connector set – 20+4 Pin ATX, 4+4 Pin ATX/EPS x2, PCI-Express 6+2 pin x2, PCI-E 5.1 x1, SATA x6 and Molex x3 cover a typical gaming build with several SSD/HDD and additional accessories.
• 120mm fan – provides cooling for internal components under prolonged load.
• Active PFC and universal input 100 - 240 VAC – more stable operation and better compatibility with the electrical grid in various conditions.

Who it is suitable for

TR-KG850 is suitable for gamers and enthusiasts who want a power supply for 1080p/1440p or even 4K configurations with a powerful graphics card and modern CPU, plus headroom for upgrades. It is also a good choice for workstations for rendering, video, or 3D, where stability under long load is important. If you are pursuing extreme multi-GPU setups or overconsumption, you might want to look at higher wattage, but for a strong GPU, this model is a logical balance.

The most sensible aspect here is the combination of 850W power, 80+ Gold efficiency, and ATX 3.1 / PCIe Gen 5.0/5.1 in a fully modular format. You get a power supply that is both current for the new generation of hardware and practical for a clean, organized build.
