Many thanks, the corsair was a strong contender and tbh I wouldn't have been disappointed with it. It's also newer than the sx500 but the 500 has a bigger fan, which helps a lot with noise reduction and equally good reviews.
I have a passive gpu and CPU so I was really disappointed a passive psu wouldn't fit.
There's also 2 ssd's in this build so very silent overall. Only noise is from the did drive when you first turn the machine on.
now you got me interested in the specs. Have been chasing silent fanless build for months now.
