Is the power brick big enough

I have a coaxial quad (900mm, 4114-400kv motors ,40 amp esc’s and 6s batteries) is the power brick that comes in the box with the cube big enough or will I fry it ( I’d prefer not to fall from the sky)? If it is to small what are my alternatives? I know of Mauch , but is very high price , do I have any other good choices?

Just get mauch - they are only $10 more than the power brick mini

The power brick that comes with the cube can do 30A continuously, 124A for a few seconds…

If that doesn’t suit your needs… get a Mauch
