actually using Seasonic (PRIME 750W) and I like it. Not that expensive but the packaging has somewhat premium feel to it. PSU exterior feels really high quality and works flawlessly. The only thing I would change is if they could add versions with sleeved cables (at least for the board + gpu), especially since the included 6+2 pins are 2-in-1 even though the instruction says you should only connect gpu 1-to-1 due to power constraints.Really hard to hide with horizontal GPU, but with vertical mount they are not visible that much (using NZXT 500 + CableMod vertical mount which I highly recommend).
