I've been in university research computing for 15 years, so large enough (~900 nodes) we need a dedicated DC, but not at the same scale as others around here.
Our racks are provisioned so that there are two independent rails, which each can support 7kW. Up until the last few years, this was more than enough power. As CPU TDPs increased, we started to need to do things like not connect some nodes to both redundant rails or mix disk servers into compute racks to keep under 7kW/rack.
A single HGX B300 box has 6x6kW power supplies. Even before we get to paying the (high) power bills, it's going to cost a small fortune to just update the racks, power distribution units, UPS, etc... to even be able to support more than a handful of those things
