780ti - do i need to change psu?

[shatpank81]

Hi

just changed my order for the gtx 770 to the ref 780ti
i have a superflower 550w golden green on its way to me which at the time of ordering would have been for the 770, but a bit worried now reading that the 780ti should ideally be on a 600w and needs certain power through the rail.

so do you think i should keep the superflower 550w sealed and send back and order a replacement?
if so what one should i get?

i have an msi b85 motherboard, i5 4460, 8gb ram and 2 x SSD's

Thanks all
Think ill stick with the 550w superflower
I just had a budget to get everything but got an extra £50 for my xbox one so put that towards upgrading from the 770 preorder to the 780ti preorder
But never even gave a thought to the power supply..
I would have bought a 650w normally to make sure but i couldnt go over £60 for the psu at the time and like the quality of superflower
