About Thermalright TR-TGFX850
The Thermalright TR-TGFX850 is built to fit inside compact computer cases. It follows the SFX standard, so it is tiny at just 100 by 125 by 64 millimeters. Because it is fully modular, you only attach the cables your specific parts need. This keeps the inside of your small case neat and helps air flow move freely to keep everything cool.
This power supply is ready for the newest computer hardware. It follows the ATX 3.0 and PCIe 5.0 rules, which means it has a native 12VHPWR connector. If you buy a powerful new graphics card, you can plug a single cable right into it. This single cable can safely send up to 600 watts of power to a card like an RTX 4090, so you do not need any ugly adapters.
When it comes to power, this unit provides a solid 850 watts of total output. It has an 80 Plus Gold certification, meaning it wastes very little energy as heat and runs efficiently, often reaching about 91.2 percent efficiency. Inside, it uses a single +12V rail that can push 70.8A, along with active PFC and DC-DC technology. This keeps the voltage steady and clean for your expensive parts.
The cooling system is both quiet and smart. A 92mm fan with a fluid dynamic bearing keeps friction low and lifespan long. The best part is the fanless mode. When your computer is just browsing the web or doing light work (under 30 percent load), the fan stops completely. It makes zero noise. For reliable power, it also uses tough 105°C Japanese capacitors to handle heat well.Thermalright TR-TGFX850: SFX Computer Power Supply with 850W capacity and 80 Plus Gold efficiency.

Reviews Thermalright TR-TGFX850
Finally found a power supply that fits my tiny PC case without any hassle. The cables are easy to plug in, and the fan never even turns on when I am just watching videos. My new graphics card connects with a single clean cable, which looks awesome.
Really solid unit for the price and it powers my whole setup without breaking a sweat. The modular design made building in my small case so much easier than I expected. I took off one star only because the cables are a little stiff, but they still bent enough to fit behind the motherboard tray.
Switching from a big standard ATX unit to this SFX one changed my whole computer. There is so much room in my case now, and the airflow is way better. I ran a hard game for three hours, and the power supply stayed cool and completely silent. A great choice for anyone downsizing their PC.
