Thanks for the reply. Yes I worked out about 280.5w

Steppers (rated current x rated voltage + 50%) = 2 x 2.8 + 2.8 = 8.4 x 5 steppers = 42w
Duet = 5w
Heater cartridge = 40w x 2 cartridges = 80w
Fans = 3w x 2 fans = 6w
Panel Due = 3.5w
Heated Bed (4 ohm of resistance according to my multi-meter at least) = 144w

I thought less complication might be a good thing!

Thank you muchly for the swift replies. That is essentially what I had assumed but nice to find out for sure.

I'm wondering if buying a different heated bed with a higher resistance would be the better way to go:

With 4 ohm of resistance that equates to 144w and so a total of around 280w with a happy amount of wiggle room lending itself nicely to a MeanWell 300w PSU. Possibly I have just answered my own question….......
