Note that your power consumption is more than just the CPU (combined TDP of 2x225W [0]). You also have to consider SSD (16x20W when fully loaded [1]), NIC (4x24W [2]), and the rest of the actual system itself (e.g. cooling, backplane).

[1] I couldn't find 14TB enterprise SSDs on Intel's website, so I'm using the numbers from 6.4TB drives: https://ark.intel.com/content/www/us/en/ark/products/202708/...

[2] I'm not sure offhand which model number to use, but both models that support 200GbE on page 93-96 have this maximum wattage: https://docs.nvidia.com/nvidia-connectx-6-dx-ethernet-adapte...

Or, you can skip all the hand calculations and just fiddle with Dell's website to put together an order for a rack while trying to mirror the specs as closely as possible (I only included two NICs, since it complained that the configuration didn't have enough low-profile PCIe slots for four):

In this case, I selected a 1100W power supply and it's still yelling at me that it's not enough; 1400W is enough to make that nag go away.
