I currently have a Corsair 750w Gold PSU, but thinking about upgrading to a SuperNOVA P2 850w for when I am able to step-up to a 3080ftw. PC Partpicker estimates 678w.
 
Is this upgrade necessary/recommended? My build is only about 3 months old, but would like to give it the best efficiency I can afford and I have heard being less than a hundred from max wattage is not ideal for the system. Clearing 100watts is recommended, but that was just from one source.
 
My other question is, do both of the PSUs come with the correct connectors for the 3080ftw?

    If you're going to upgrade, go at least 1000w and READ THE REVIEWS.
     
    Gold performs just as good or better as Platinum if you're comparing the same platform, about a 2% efficiency difference.

    Yea, since I've posted this, I 've caught more info on the BIOS update and with all the things I am hoping to do with my system, it makes sense to got 1000. Thank you.

    EVGA recommends a minimum of a 750W PSU for all their 3080 cards..But that's based on what they think an average PC is..To get a good estimate of your specific PC wattage need and to see the recommended wattage, use the OuterVision Power Supply Calculator.
     
    An RTX 3080 FTW3 needs three 8-pin (solid or 6+2) PCIe power connectors.

    Do you need a better PSU?..Maybe, maybe not..Depends on the rest of the components you have in and connected to your PC.
     
    See what the PSU calculator says and roll from there.

    Hey thanks for the reply. I ended up going bigger than I maybe need to, but I want to do some overclocking down the road for the sake of learning. So I got a Seasonic Prime TX Titanium 1000w. The PSU market is slim, so I just wanted to get something that will last, even if it is overkill for now.
