Shopping list for 24VDC upgrade, is it enough?

Just to make sure since you already seem to have the 50W cartridges and it isn't fully clear to me whether you mean those or new ones when you say you ordered them: you will need to switch from 12V cartridges to 24v cartridges. Running 12V cartridges at 24V quadruples their use, and you don't want 2x200W on your hotend.

Thanks for the warning! of course I've ordered a couple of new 50W 24VDC cartridges

@the_dragonlord As ever, I'm confused by your post. In your first post you put .....

"Heating Cartridges: 4,16A"

Assuming you mean 16A for all 4, then that would be 4A per cartridge, which at 24V would be 96Watts each (which is alarmingly high).

But then later you say .......

"I've ordered a couple of new 50W 24VDC cartridges"

While a 20A PSU will be more than sufficient, which is it? Is it a) 4 x 96Watt cartridges drawing 16A or b) 2 x 50 Watt cartridges drawing around 2 Amps each = 4 Amps in total?

I suspect he means 4.16 A total for 2 x 50 W heaters

That's just confusion of the decimal separator between German and English "4,16" means "4.16" in this case.

No, I meant 4.16A for both...we use , intead . as decimal separator...
