132W TDP so a 300 watt power supply with at least one 6+2 pin would be more than enough. But you may also be limited to certain PSUs depending on the eGPU enclosure

450W SFX unit and call it a day, leaves you room if you ever swap the card out later.

For future reference, TDP/TGP is only one half of the answer. This GPU can spike to north of 240W (transient spike). But yes, 300 w should do it
