A Samsung 970 Evo draws ~6W-10W max. @ 3.3 V and usually a lot lower than that. So y'all got heaps of power to drive that.

Thermal throttling, you want to pay attention to. These are not drives you leave bare on an adapter board with no dedicated cooling fan. You need heatsinks or dedicated fans or both if they are working hard. (and a reminder that many of the drives we use don't work too hard all the time... only occasionally).
