Power Rating of StereoPi

Greetings,
What should be the input voltage and current rating of StereoPi so that every component(2 camera, mouse, keyboard, Compute Module) will work properly?

Re: assert false in file qasciikey.cpp line 495

I followed the solution given in this link
My left and right image viewer along with disparity appears for about 2 seconds then it turns off my MobaXterm. I notice that whensoever two of my camera turn on together my StereoPi eventually turns off.

Re: Monitor turns off when running "rosrun image_view stereo_view stereo:=/stereo image:=image_rect_color"

Thank you for your quick response Sir
I have tried both the methods but those did not solve my issue

Also when I run "raspistill -3d sbs" it displays the image output of one camera but did not hang.
