Cabinet power with powerbar

[mike boss]

I have perhaps a stupid/novice question, but figure no harm is asking.
I'm just finishing up the attached cabinets.
The yellow cabinet is a Bad Dudes with an LCD monitor.
In the cabinet I have a Home Depot lighting fixture and LCD monitor plugged into a powerbar.
I also however plugged the power supply into the powerbar. The power supply has a couple extras plugged into it, 12v for the cold cathode lighting, and 5v for the RGB to VGA adapter.

Question is this, I have everything going into the powerbar and the powerbar is left in the "ON" position. But with the backdoor on you cant access the powerbar. So I simply have the plug end coming out around the side of the cabinet. When I want to power the cabinet I simply plug in an extension cord.
Could this cause any issue ?

So are you saying you are turning it off and on by plugging/unplugging the cord to the machine?
I don't see any problem with this, other than the wear and tear on your cord plug and the wall outlet. (or extension cord plug, if that is what you are using.)
If you are using an extension cord, it needs to be a good heavy one, at least 16 gauge wire (14 gauge is probably better), and properly grounded (three prongs on the plugs).

LOL! I guess the above post I made was a lil long winded.
Everything plugged into powerbar, powerbar left in the "ON" position, when plugged into the wall (and/or) extension cord cabinet turns on.

I know a friend of mine said in North America the power is clean, steady, not like Sri Lanka where is from.
I figured we don't get many surges, and the ones we do are protected from because of the powerbar and it's built in surge protection.
I just thought that perhaps all elements of the cabinet not being turned on by a switch could be an issue ?

Both my Final Fight and Bad Dudes have decent powerbars with surge protection, and the cord I think is sufficient.
However I'll get another. I use the machines in my garage, and it's not easy to reach around behind them.
Using the powerbar made sense for elements like the LCD monitors and light fixtures as they plug right in.

I want to have both Bad Dudes and Final Fight's internals plugged into separate powerbars.
Then when I want to play plug in the powerbar to the extension cord.

EDIT - would a cord like this be sufficient ?
