Need HELP... JPAC to console setup question

Thanks in advance to anyone that replies.

I ordered a JPAC and the XBOX and PS2 console adapters, I am planning on hooking this all up in the next few days but had a couple of questions before i do.

On the installation information for the Jpac website they mention that the power supply could be a problem, but they say the JPAC gets power from the computer through the USB/PS2 port; I do not plan on having a computer connected at all and only using the xbox/ps2. Would this mean the JPAC would get power from them? or would it need its own power? and with this set up do i need to remove the power supply, and if so how will my monitor get power (actual arcade monitor) im putting all this in a Darkstalkers arcade cab, let me know if you have any questions, thanks for your help.

it would get power from the controller port.

As Shinji said, and to further answer, you will leave the existing arcade PSU in place to power everything else that requires power in the cabinet.

You might want to look out for the power supply though.I’m pretty sure the jpak site mentions something about needed to make sure some of the power supply is removed or not connected to the jpak. Isn’t this correct guys?
