Hello
i have a pc that is pretty good now, but i want to upgrade my R9 280x, but my question is, should i upgrade to 2 280x(what i want) but if i do, i have to get a new power supply since i only have a 750w now, and if i get 2 r9 280x i need atleast 850w. but! do i get another 280x or do i get 290x or 780/TI, what is the best option right now ? (srry my english)

What exact 750w PSU do you have? If its a quality unit then 750W is more than enough.

I have a Silver Power SP-S750

If its that one, then you are good to go with another R9 280x.

But you said bronze 80+ so i doubt. Exact model?

the Model Name is: SP-S750 and, i have a link to a store that sells it, but that site is in Norwegian, so i doubt you would understand it : https://www.komplett.no/silver-power-sp-s750-750w-psu/771926

Yeah I would not trust that PSU.

So, i should get a new PSU, but what card should i get, one more 280x or a new and better single card ?

 

[Novuake]

I would get another 280x.
