FPGA board's power consumption?

[Altera_Forum]

How to evaluate the power consumption of the FPGA board in the PCIE slot? Thanks.

Idea 1: Use a PCI-E riser cable on which you will cut the power lanes and put a multimeter in. 

 Idea 2: Measure your computer power consumption in a specific scenario with a Kill-A-Watt. Power it down, install the FPGA board, and measure the power consumption again in the same conditions. The difference should be approximately your FPGA card power consumption.
