P4000 - is it possible to use PCIe x4 slot

I’m wondering if it is possible to use NVidia P4000 GPU in PCIe x4 slot given that I properly connect the external power using the 6 pin GPU cable?

My question is due to TDP of the card is 105W, the PCIe x4 slot can supply 25W of power and the 6 pin cable is 75W, so technically this setup will be 105W - (25W + 75W) = 5W less the required power.
