That's what I was thinking, the motherboard doesnt care but that site I show you , make me wondering... Because in the CB model it have same 500 w psu like i have OR the psu is not the same but better and still 500w... Its the way they explain things, there 's a huge lack of information ... I know i need at least a 600 w psu , i looked on Nvidia website. I 'll need also 6 pin and 8 pin connector and right now i have 2 x 6 pin , it's enough for the standard gtx 980. If I buy a transition connect from 6 to 8 pin and run 980 ti on my 500w with transition conector, what will happen? Will it works..?
