    The RM850 PSU was packaged well. Like most Corsair products no paper instructions are included. I watched a few videos linked from the website and installed it in a MSI Gungnir case. Cable management was easy save for the size of the PSU requiring removing the PSU twice to change arrangement of modular cables. PSU did not have +12v output when I tested the computer. Switched it out with known good PSU and the computer worked. Returned to Best Buy and bought the RM850x model that worked great.
