The seasonic would be better. Better quality and they manufacture their own. Corsairs in the CX series are manufactured by channel well and use cheaper capacitors which is why they're usually cheap. Not sure why, everyone wants a top end cpu, top end gpu, then wants to run bargain bin psu's in their system. Doesn't make for good sense to want to power $1000 worth of equipment on a $40-50 psu. I guess that's why they're so popular, it's everyone's go-to lately. But then there's a reason they're all but giving them away.
