I'd get the 12v -6.5A -78w one myself. May as well for the extra few pennies. Gives you the option to add stuff.
My control box has got 60v, 36v, 24v & 5v in there!!!! If/when I need 12v I'll get a step down unit from my 24v. It's looking a bit ugh with psu's

Sorry I just don't see the point.
all you are doing is just burning electricity up and putting heat into to the control box

Why so many.? . . . You are just melting down the other electrics and heating the planet with all that wasted electricity.!

Regards a larger PSU for Geoff then he's only controlling a few relays and the BOB, He'll be lucky if pulling 1A total so he's still got 2.5A spare with 40W 3.5A PSU.

Geoff go with Clive's suggestion the 36W will be fine.

They only use what they need.
60v for the Nema 34's.
36v for the Nema 23's. (Although I now know they could probarbly go on the 60v fine).
24v for BoB spindle, estop, limits.
5v for the BoB pul/dir etc and SSR relays.

It's been added to over time and I'm still learning. In reality I could ditch the 36v as suggested above and also ditch the 5v by using a step down module from the 24v for the needed 5v. Only recently realised they existed lol. I'll wait until they fail and re-jig it all later on. That's why I got the larger than needed 24v supply for when this change occurs.

May be worth going for a bigger wattage. These don't fail very often imo. See how much is connected to it.
Mine only powers the 12v-24v part of my BOB and that's it, but I still stuck a 24v-60w on there. I can always get a step down unit if I ever need to add a 12v line.

So with yours being a 12v as long as you get the same voltage unit a bigger current and wattage rating won't matter.

Just a note that automotive relay coils generally take a lot of current compared with GP electronics ones. I haven't looked at your wiring, but I wouldn't use oneanywhere but on a vehicle.
