Which redundant power option fits my X450-G2?

It depends on whether the switch is a PoE model. Extreme documents the RPS-500p for the non-PoE X450-G2 models, so it is not the listed backup for the X450-G2-48p-10GE4-Base on this page. For PoE models, the documented external option is the EPS-C2 chassis populated with one to three Summit 750 W AC modules (part 10931). Inside the switch, the X450-G2-48p takes its own internal power supplies, and its PoE+ budget grows with the number and size of the supplies installed.

How do these switches stack?

The X450-G2 uses its two rear 21 Gb ports for SummitStack-V84 stacking over passive copper QSFP+ cables, or it can stack over two front-panel 10 Gb ports (SummitStack-V). Extreme supports up to eight X450-G2 switches in a stack. The X450e-48t stacks through its two rear stacking ports with standard SummitStack cables, and an XGM2 option card adds 10 Gb alternate stacking ports. Cables and modules are on the SummitStack page linked above.

Is the 750 W supply a drop-in for the X450-G2?

No. In the X450-G2 family the 10931 is used inside the EPS-C2 external power system, not in the switch's own power supply slots. The X620-16p is the switch that takes it as an internal supply.
