Hello. I was wondering if this Chieftec Nitro Series BPS-950C 950W PSU will be able to handle R9 290X crossfire? I've been reading abit, and I think it is made with same platform as Corsair TX. I got a i7 4770k, and I will probably buy a second R9 290X in the future. Will it be okay, or do I need a new PSU?
