How much headroom when upgrading the PSU?

I'm looking to upgrade my EVGA G3 850W. After looking at various PSU calculators, I'm pulling around 800W. (5900X, RX7900XT, AIO, multiple fans and storage devices).

Should I aim for 1000W ATX 3.0/PCI5 or maybe go higher 1100W-1300W?

I've ordered a MSI MPG 1000w PCI5 PSU, which should give me plenty of future-proofing over the next few years.

PCI-E GPU connector - Is that the 8-pin connector on the bottom of the MSI X870E boards?

The 7900XT seems far happier on the new PSU I haven't had any black screen 100% fan crashes since which was a semi regular occurrence before.

The EVGA G3 was 7 years old so might have been on it's way out.
