750 Watts or more?

[quazect]

So, I'm thinking about an ITX build, and I have it all planned out, but one thing worries me. Is a 750 watt (80+ Platinum SFX Form factor) PSU even able to handle a 3080 ti and an i9-12900k? If not, do you guys have any good suggestions for SFX form factor PSU's?

I'd really doubt it. I'd put 1000 watts for a normal build, let alone a ssf build. 

What specific case are you using? Can It only accommodate sfx psus?

[An0maly_76]

Agreed. I run an 850W for my 3060ti.

sf750 is good even for 3090+12900k

optimum tech did a build with an sf750 and 12900k+3090

you need to undervolt though

I would grab a decent 1000w for such a scenario.
