Review on 💡 Silverstone SX750-PT 750W SFX Power Supply - Fully Modular, 80 Plus Platinum Certified by Shane Mack

Glad it works. But that's probably the only thing that's good, apart from the fact that it's not a very good power supply. By definition, this is an SFX power supply, meaning it's designed for use in a smaller case, after all, there are regular sized power supplies out there. at a much lower price, so whoever buys this is building a small PC. Since it's a smaller computer, it will most likely be on a desk next to a working person. At least that's how I set up my computer next to the monitor and keyboard I'm typing on. Therefore, noise is a major concern for the use case. In this configuration, this power supply fan is very audible and is particularly annoying when the PC is under load. In fact, I bought a premium 750W PSU and compared the noise that PSU was making to before I installed it. My computer is a Ryzen 9 5900X with an RTX3080 card that generates heat under load. Using the Sound Meter app for an Android phone, this power supply generated around 50-55 dB under load (60-70 °C CPU and 75-80 °C GPU, depending on games/apps). After replacing the PSU (just the PSU as everything else is the same) I measured 35-40dB at about 30cm away from the PC case, the Cooler Master NR200. It was the audio part as shown by Android Sound Meter. That's a difference of about 15 dB. Annoyingly, the PSU fan spins pretty fast under load and makes a very annoying loud noise that sounds like the plane is about to take off and is quite tiring. The other PSU I compared, which I couldn't get hold of at first, performs much better in terms of noise. Under the same load I can hear the case and CPU fan but not the PSU fan, I use Noctuas so it's surprising they make more noise than this PSU fan. But in case I am hard of hearing, Android Sound Meter proves that the noise between two power supplies is about 15dB lower and this one has a louder noise. I agree with other reviews on this point, the cables are indeed very stiff and complex. Diversion in a small package so it only exacerbates the problems with this PSU.
