Depends on the datacenter. Any modern datacenter won't have an issue. However, if you didn't do your research and wound up in something that wasn't built to current specs, I can easily imagine a 42U rack overloading. Similar example: there's a tier 1 network provider with a solid datacenter business; I had servers in one of their facilities during the period in which blade servers were becoming common. They literally ran out of power; we had some empty racks with a contract allowing us to turn on power for them at any point and they couldn't fulfill it. Looking back on the specs for 80s and 90s datacenters can be really amusing in retrospect.
