Virtex 7 2000T board current estimate

[nth_degree]

I have a PCB that takes 12V input and hosts 4x Virtex 7 2000T FPGAs as well as connectors for two FMC daughter boards. What do I need back of the envelope? Best recommendation for a compact regulated power supply for this job?

Any desktop PC power supply should work.

Power consumption of any FPGA (and Virtex 7 in particular) is VERY dependent of RTL, loaded into them. Blank chip can consume a 10-100mA (you can find out exact number in Datasheet), fully loaded can consume up to tens of Ampere (close to 100A, IMHO)

The capsule of a Virtex is about the same size as a CPU, so probably no more than 50W.  Better estimation might be done by the size of the radiator, if there is any.
