Thanks @d.cochran, I forgot that I probably should have mentioned that I have run Six with 18 servos from a 7.4V lipo without any brownouts, this is because LiPo batteries can provide the in-rush current that the servos demand.

The difference is that switching power supplies, or even linear voltage regulators, have a very hard time meeting the burst current demands of multiple servos which is often over 10Amps. This was one of the largest reasons we are now using LiPo batteries connected directly to the servos (Fuse protected of course) as opposed to using voltage regulators.

@Anthony... (read Jeremie's last few posts)... 10amp power supply can't handle the initial inrush of power that those servos require... We have been through this before in another thread about your power supply (a while back) not handling the initial inrush need to start servos moving.... Again, what you experienced was a brown out that triggered the ezb reset... Minimum power supply should be 20amps in my opinion...

For my inMoov project I am looking at a 60 or 100amp power supply....
