Power supply Thermalright TR-TB850S ATX 3.0 850W 80 Plus Bronze PSU

The Thermalright TR-TB850S is an 850W ATX 3.0 power supply with an 80+ Bronze certification, aimed at mid-range to more serious gaming and workstation configurations. It offers stable power delivery at 100–240 VAC, active PFC, and efficiency up to 85%, which is a good base for a system with a more powerful GPU. With the available PCI-E Gen5 12VHPWR connector, you have the option for modern graphics cards without relying on adapters. There is no RGB or modularity, but you get a simple, black ATX unit that does the job without unnecessary extras.

What you get

With a real power output of 850W and DC output lines of 3.3/5/±12 V, this power supply comfortably supports a combination of a powerful CPU and a serious GPU, plus several drives and additional fans. ATX 3.0/PCIe Gen 5.0 compatibility and the 12VHPWR connector allow you to use modern graphics cards without additional adapters or compromises. The five SATA connectors provide space for a combination of SSD and HDD, while the three Molex connectors are still useful for fans, controllers, or older peripheral hardware. A 120mm fan takes care of cooling, and the active PFC helps with more stable power delivery and better utilization of energy from the grid.

• 850W Power – sufficient for a serious gaming or workstation build with a powerful GPU and lots of peripherals.
• 80+ Bronze certification and up to 85% efficiency – less heat loss and more stable operation under load.
• ATX 3.0 and PCIe Gen 5 support – ready for modern configurations and the next generation of graphics cards.
• PCI-E Gen5 12VHPWR connector – direct power delivery to modern GPUs, without relying on adapters.
• Two 4+4 Pin ATX/EPS connectors – convenience for motherboards with more serious CPU power sections.
• 5 x SATA and 3 x Molex – enough connections for several SSD/HDD drives, fans, and additional devices.
• 120mm fan and active PFC – better stability and temperature control for daily and gaming use.

Who it is suitable for

The TR-TB850S is a good choice if you are building a mid-range to high-end gaming or workstation machine with a stronger GPU and want ATX 3.0 and 12VHPWR without entering the price range of higher certifications. It is also suitable for upgrading an older system that you want to prepare for the next generation of graphics cards. It is not the best option if you are chasing maximum efficiency or strictly require modular cabling.

The combination of 850W power, ATX 3.0/PCIe Gen 5 support, and a 12VHPWR connector in a non-modular, simple black chassis makes this power supply a practical choice for a modern gaming configuration without unnecessary decorations.
