So I (finally) managed to snag a 30 series in the form of a 3070ti FTW3 @ Microcenter.   Question is with a recommended PSU of 750w, will my seasonic gold GM-650w do?  Every PSU calculator I run my machine through says it is, but every spec list recommends 750w?  
 
Should people be following the PSU recommendations explicitly?  Is there wiggle room (as the PSU calc's suggest?)  

If your doctor recommends something I suggest you just listen and don't ask questions.

Should be perfectly fine. 

Thanks doc.

I mean a 650 Watt power supply should be able to run a 3070 Ti. The new 30 series graphics cards have significantly more overclocking potential. So if you overclock your card, it will require more juice. I think if you don't overclock, you should be able to run a 3070 Ti with a 650 watt power supply. Otherwise, you could always just go to MSI afterburner and lower the power limit so that it does not take up a lot of power.

you should be fine, I ran a 3080 on a 620w bronze from seasonic for a little while just fine.
