Will 1200w be enough for a 5090?

Probably but there is obviously no official spec for the 5090 yet. Wait til it exists then check compatability.

1200 watt is a reasonable assumption, but as the other poster said: these things will be better defined at launch
Thanks sadly i was offered a unit thats worth £350 for £100 sealed locally - scrapped project, So pulled the trigger, hopefully it is
it should be fine, Seasonic are known for over engineering their higher end PSU`s to be beefier than their wattage rating suggests.
I’ll be flabbergasted if it isn’t. Should be fine.

Id happily use my 850W not that I could afford 5090 anyway

Almost certainly yeah.
neither can i - but i have saved for over a year for a good pc

it will be fine you have to remember that our friends in the US run off a 115v domestic supply, so they can only draw a continuous current and power that equates to 1200-1500w max before they start to cook their wiring unless its an oven or something like that

Currently building a small nuclear power plant in preparation for the 5080.
I’d be surprised if it uses anymore than 280w.
Think people would struggle with to much heat in a lot of PC cases if a system did draw 1200watts
I think they'd crash and burn if it actually needed a 1200W PSU, let alone anything beyond it. There will always be the odd unicorn-vomit black-hole-cooled AIB that needs a bit more, but for the average power-gamer, PSUs top out at 1000W.
There's also the prospect - and I suspect this is likely - that the EU will slap a maximum on power draw in the next few years. They had a go at this for 8k TVs but left loopholes. I expect those loopholes to be closed when they come for GPUs. They will come for GPUs. Nvdia has made a lot of headlines lately, so they will be in Thierry Breton's crosshairs. Expect a max TDW of 200W.
