ramps 1.4 wiring + psu (3 replies)

hi,

I would like to know which power supply I can use for the ramps 1.4 electronics.

I do plan to use a heated bed.
According to the wiki, I will need 5 + 11 A.

I found the SNT MW200-12 from MEANWELL for ~40€

It does 12 V and 16.7 A. Now I wonder if .7 A overhead is big enough if some peaks occur.

How much more than the bare minimum of 16 A should the psu be capable of?
What other psu would you recommend?

The cables of my stepper motors are wrong.
Red and blue are swapped in the connector.

Would this also work? The connectors came wired up and I wonder why they are wrong.

Thanks for your help
