A normal x16 PCIe slot has always been able to supply up to 75w since the beginning.
A normal non-GPU PCIe x4/x8 slot that you'd use for a NIC provides 25 W.
For a 25G NIC, I’d be perfectly unsurprised if it demanded an x16 slot. I’d be more surprised if it didn’t have a power connector like a video card, though.
