Thermalright TR-TGFX850W, White: A compact SFX power supply with 850W output, 80 PLUS Gold certification, full modularity, and ATX 3.0 / PCIe 5.0 support. Its zero RPM fan mode ensures silent operation at low loads, while the native 12VHPWR connector makes it ready for the newest graphics cards.
About TR-TGFX850W
The Thermalright TR TGFX850W White delivers 850 watts of stable, efficient power in a remarkably small body. It is built for modern small form factor gaming PCs and workstations that run the latest graphics cards and processors. With a native 12VHPWR connector, it fully supports ATX 3.0 and PCIe 5.0 standards, so your system is ready for future upgrades without messy adapter cables. The white housing also adds a clean, stylish look to any build theme.
Efficiency is a strong point of this unit. It carries an 80 PLUS Gold certification, which means it reliably converts over ninety percent of wall power into usable energy for your components. This high efficiency reduces wasted electricity, lowers heat output, and keeps your electricity bills in check. The all Japanese 105°C capacitors inside provide the toughness needed for years of demanding use, giving you confidence in the long term reliability of your PC.
The fully modular design makes building and maintaining a small case much easier. You connect only the cables you actually need, which cuts down on clutter and allows air to move freely inside the cramped space of an SFX chassis. The dimensions of 100 by 125 by 64 millimeters fit standard SFX mounts, making this power supply a strong choice for popular mini ITX and compact ATX cases. An included ATX adapter bracket also lets you use it in larger cases.
Clever cooling keeps the unit quiet during everyday tasks. The 92 millimeter fluid dynamic bearing fan stops spinning entirely when the load is low, creating a zero RPM mode for silent operation while browsing or watching videos. Even under heavier gaming loads, the fan spins smoothly and stays controlled. A full suite of protections, including OCP and OPP, guards your valuable hardware against electrical faults, and the five year warranty backs up the quality of the product.

Reviews TR-TGFX850W
Super happy with this little power supply. Fits perfectly in my Mini-ITX case and the modular cables made the build really clean. The fan doesn’t even spin during regular desktop use, it’s completely silent. Running an RTX 4070 and a 7800X3D with zero issues.
Really solid SFX unit for the money. Love the white finish, it looks great through the mesh panel of my case. Cables are a bit stiff to route in tight spaces, but that’s common with this form factor. Powers my 7900 XT system without breaking a sweat.
Bought this for a compact home office build and it exceeded expectations. The native 12VHPWR connector meant I didn’t need any ugly adapters. It stays whisper quiet and the five year warranty gives me real peace of mind. Highly recommended for SFF enthusiasts.
