Review on 💡 Corsair SF450 SFX Power Supply - 450W, 80+ Platinum Certified, Fully Modular (CP-9020181-NA) by Sean Patel

In short, you either need it for your build or you don't. If you have SFF, get that. I have a very small case so this is pretty much the worst case scenario for a power supply. This may be due to heat leakage from other components like my hot ASF 1070 FE, but from what I've seen Corsair prioritizes noise over heat dissipation. The thing gets quite hot, maybe around 50-70 C? I put my hand on the body where it was and it was quite hot. That being said, they're really your only option for an SFF power supply at the moment, and they're very high quality. It's modular and the cables that come with it look fantastic and are really good lengths. Some might say it's too short for their system, but it's almost perfect for mine (there are some bells and whistles, but that's to be expected). If you're deciding between the SF750 and this one, Optimum Tech made a great video on this power supply, but what you need to know is that it can handle newer GPUs at maximum load, even Intel's overclocked 10900k. You should ideally get the SF750 if you can find it in stock, but it will definitely work.
