You F.U.C.K.I.N Retard Corair use Seasonic as the base for most of their PSU's......A Rog strix 650 watt PSU is a Seasonic dumb arse. A Corsair 650watt PSU is a Seasonic. Do you now understand?
Oh wait Seasonic cables are not what you asked for you muppet, oh and neither are Corsair ....just cause it doesnt say for asus rog does not mean it will not fit. Next time someone tries to help you don't insult them as you just end up looking like a fool.
