Been a while since my M1 was built, what's the best/quiet PSU that can do 500W+, should really get an sfx psu so I don't have to have an ATX one sitting on the outside with cables going everywhere.
Also 'quiet' is subjective. Some people are down right anal about noise when it comes to PCs and power supplies. How quiet do you want? Personally I find the GPUs the most noise in a build but that's just me I'm not so demanding as some when it comes to noise.
