So back in June i purchased an EVGA Supernova 650 Watt power supply. I never opened it due to the fact that it was for a build that I was buying parts for. Yesterday (9/8/18) I went ahead and opened it up since i have recently acquired all them parts for my new computer and am getting ready to assemble it. However, I notice the 6+2 pin cable (for the graphics card) was not in the box. I purchased it new from Amazon. I am kinda new to online customer service issues and am wanting to know how to proceed. I have bought numerous EVGA products before with no issues so I have really never had to do this before. Any advice would be appreciated.
