Nobreak não senoidal prejudica o PC? estraga fonte PFC ativo? onda quadrada? desempenho do pc gamer?

Does a UPS damage a power supply with active PFC? There's a controversy surrounding whether a UPS would damage a PC or if the noise caused by the square wave would damage the PFC (Power Factor Correction) of the power supply. The big problem is that there's a lot of misinformation, many theories, and a lack of scientific studies on various subjects. This creates a favorable environment for speculation and even for the market to exploit product loopholes and push new products onto consumers through these controversies. Therefore, let's do something more scientific here to eliminate some of these controversies and speculations. This type of discussion is quite common in the world of PC gamers, where there are debates about whether a UPS would damage the active PFC of the power supply or if it would cause the computer to lose performance because there would be too much noise. This noise caused by the square wave would pass to the motherboard and cause the PC to lose performance because it would no longer be possible to distinguish between the binary values ​​0 and 1. And so on, various theories on the subject continue. Okay folks, this question came from a colleague subscribed to the channel who asked about PFC and UPS. Since we didn't have anything concrete (until now), we discussed academic issues, whether or not there would theoretically be any harm to the PC. So we stepped away from the academic world and did 3 tests: 1 - In a very basic power supply, with a simple transformer, a diode bridge and a capacitor, that is, a very primitive DC power supply, to assess whether or not there is noise passing to the next stage; 2 - In a low-quality PC switched-mode power supply (one of those very cheap ones); 3 - Finally, in a good quality power supply in a working PC. In this last test we also checked with a benchmark whether or not there would be any harm to processing, in 3 attempts, one on mains power and another in battery mode (disconnected from mains power) and thus we took an average to assess whether or not there was a loss of performance. Check it out, I hope it helps everyone. If you enjoy this channel, support our work and receive benefits:    / @tudoemvolta
