it could cause you issues, try to connect max 2 risers per cable
Remember on a Sata connector there is only a single 20-18 AWG wire actually providing 12v. You should do what the person I quoted said and just run 2 per cable run. I have hundreds of miners runnning 2 per with no issues whatsoever, if you bump that up to 3 you will eventually have fires/failures/sadness of some sort.
