Is it safe to plug both pcie cords in my gpu?
I got my rm750x (RPS0109) in 2020 brand new and didn't really inspect everything in the box because I had a guy building the pc for me. Its been years since my last pc upgrade and I decided to do it myself. I'm getting a 9070 and as I was getting another pcie cable from the psu bag I noticed I only have a sleeved one. It was never used and still tied up. The sleeved one doesn't say it's type 4 but has the model number 34-0 00371 and a Google search says it's compatible with type 4 psu but I want to get a second opinion. Is it safe to use? If not can I buy the cable stand alone?
