Review on 💡 Thermaltake Toughpower Grand RGB 850W Power Supply with 80+ Gold Efficiency, Smart Zero Technology, 256-Color RGB Fan, Fully Modular Design, and 10-Year Warranty by Abhey Rai ᠌

The first copy was with a defective fan. The unit was installed with the fan facing down and the valve made rubbing noises when spinning up/stopping. I took it off and upon inspection I found that the fan plays if you turn the unit over in your hands or shake it a little. Took it back to the store. The second copy was already caught without a marriage, there was no backlash of the turntable at all. Initially, I also put it with the valve down, since the case has a hole with a filter for air intake from below. At the same time, there was also a very quiet, barely distinguishable sound from the fan at startup. Probably such feature of a design/bearing of the fan. Turned the valve up, it works quietly, well, the backlight became visible in the case. I didn’t return it anymore, because at that time there was no version with RGB sync on sale. When buying, immediately check the fan play in the store - twist the unit in your hands, shake it slightly, it should not make any sounds. However, I give it 5 stars. If you are building a quiet system, then this unit is more than suitable! Although because of the valve it would be necessary to put 4.5.
