Will a 100W PSU be enough?

Basically, the topic. I've seen the matter discussed on the forum before, but with no definite conclusion.
I'm planning to reassemble what remains of my old printer into a functional machine and was about to get the PSU. The heated bed is main's powered via an SSR, so the only parts consuming power from the 24V rail will be the hotend heater (about 30W), 4 steppers (?), and Duet+PanelDue (?). All of the fans will run from a separate 12V PSU.
Does anyone have a rough estimate of how much 3 2.8V steppers ran at 1.5 A would actually draw?

This is voron electronics video. You may found recommendations that are related to your configuration.
They recommend a 200W fanless 24V meanwell.

Some guidelines for total power required here: https://duet3d.dozuki.com/Wiki/Choosing_the_power_supply#Section_Total_power_needed
100w may be enough depending on your hardware. I use a 200w and there is substantial headroom, but I think I was still over 100w with everything I have connected.
