Thanks Cliff I used this one: https://seasonic.com/psu-calculator/
Looks very similar but will give the one you post a try and see if they both agree

Check this one out also Andrew, seems to have more connections.
EVGA - Products - EVGA SuperNOVA 850 G2, 80+ GOLD 850W, Fully Modular, EVGA ECO Mode, 10 Year Warranty, Includes FREE Power On Self Tester Power Supply 220-G2-0850-XR - 220-G2-0850-XR
Andrew, again you mentioned an X299 system. Those CPUs are 140W which will require more power. Also, are those values overclocked values? That can add a lot more as well. Those calculators seem to be all over the place, don't they. 650 W to 850 W.
Personally with today's systems I wouldn't go with anything less than 850. This also gives you breathing room should you need it.
That said, I myself run EVGA powers supplies in both my systems. Both 1000 Watt, both fully modular. One is the EVGA SuperNova 1000 P2, the other a SuperNova 1000 G2. Very similar to the one posted by OldMike65.
I really like my P2 because is has an Eco Mode switch that basically keeps the fan off unless the system is running full power. This helps keep things nice and quiet.
I'm not advocating you need a 1000 watt PS, but I think 850 should be minimum for high performance custom built rigs.
My two cents.
Yeah I got the higher powered one for the extra cables you get. But, I really didn't need all that power either. Still covers me though should I ever need it :)
And yes, really nice power supplies. Especially being fully modular.
My thoughts and opinions.
Right off the bat, those so called power supply calculator programs is nothing but Donkey do do dipped in chocolate.
Useless.
My suggestions are simple.
We know the top 3 brands.
Corsair
EVGA
Seasonic
Which brand do I want?
Any of the three will do just fine. Do some price checking and go for it.
How much wattage should I get?
A lot more than you need.
My last build has a EVGA 1200W/P2. That is a lot more than I will ever use but more wattage than needed hurts nothing.
Some times it helps. This 1200W power supply will give every thing it is requested of and only work about 30% of it's capability. This means it will run cooler, quieter and most likely last longer. It also mean I can cram more goodies in my system later on and not worry about power. Power supplies that don't have to work to hard put out a cleaner supply of volts and amps. It was also priced right.
Modular or (????).
Always modular. Once you go modular you won't go back to other types.
You will be able to do a much cleaner and neater build with modular. Later, if you add another goodie, just plug in another cable. Can't get simpler than that. I like simple.
How many leads? (cables)
More than you will ever need because someday you just might need them. Buying extra leads later can be very costly if you can find them.
How much should I spend?
Simple; as much as it takes to get more than you need at this time. Lots more is even better.
Think, think, think.
A power supply is the most important single piece of hardware in your system. The power supply, powers eveeeery thing in a system. The power supply is the root of this computer tree that is being built.
