Review on Seasonic FOCUS GX-850: The Ultimate 850W 80+ Gold Modular Power Supply for Gaming and More - SSR-850FX by Steven Lesperance

Power supplies are quite simple - they either work or they don't work. This one works. First, you get a PSU tester in the box so you can make sure it's ok before installation. It is very nice. Connecting everything and the cable was only possible to find out that your power supply is bad. So it's an issue with your MB, CPU, RAM and GPU on the bench only to find out it's the PSU. It was great to start assembling knowing that the power supply works. The cables are of high quality and are enough to control almost any build. This includes old Molex connectors in case you need them (I have). I gave it 5 stars for its noise level because I couldn't give it a 10. He doesn't make any noise. And I'm not talking about hybrid mode, I'm talking about the fan all the time. Under normal loads, it just doesn't make any noise. I'm sure if I were packing a power-hungry CPU and GPU in my box I could point that out, but with the slightly overclocked R5 3600 on a TUF Gaming x570 motherboard and an RTX 2060 Super it doesn't sweat or make any noise. Great power supply, nicely packaged and dead quiet. It doesn't get any better than that.
