I have a rig of 4x GTX1060. Together they are drawing 350 W at the wall, which is much less than this PSU (730W) can handle. I would like to expand my rig to 6x GTX1060. But this PSU lacks 6 PIN connections and also SATA connections for raisers. You can check its connections here: http://www.xilence.de/en/products/power-supplies/performance-a-series/xn063.html

Are there any adapters to expand PSU connections? Is it safe to do?
