Anybody running a 2080ti

I'm hunting down some 2080ti atleast 5 of them to start another rig . I'm wanting to know how much power it uses. Based off the internet it says around 250w but if someone using it I would like to know . But based off the internet would I be OK if I purchased a 2000w psu server 80 platinum? What's is the best motherboard for those cards. I was thinking about the btc-37 riserless , i am using one now but I come to not liking how I can't space out the cards to my liking . But any extra info would be much appreciated. Thanks in advance
