I haven't used Teleios sleeving yet, but, I have been using Paracord sold by Mainframe Customs. It's a pain in the rear for a 1st time sleever, but I still highly recommend it! 🙂
but if you want to buy cables that fits to your PSU? i can not find enny colored ones that is made for that PSU after a quick google. i have corsair PSU and i can get for mine.
are you going to do it your self or get others to do it?
