Possible ???

Hello,

For my arcade controller I want:

two Perfect 360's
an illuminated trackball
all the button's on the top illuminated, # of buttons about 22

I'm wondering can I use the I-PAC4 (56-input) Keyboard Encoder
to power all this stuff?

Will a 300watt power supply be enough?

Thanks

If you are asking whether all that will interface to the computer via an I-pac, then no.
You will need a separate interface for the trackball.

If you are asking whether you can drive all the lights from the +5v connector on the I-pac, then possibly, but I wouldn't.

I would look into driving LED's directly from your computer's power supply.
The draw on LED's is alot lower than incandescents, and you won't have a huge heater inside your CP that way.

Should I just run the perfect 360's off the I-PAC and then the lights off the power supply?

And could someone give me a site where I could learn how to link LED's with my power supply.  So I don't fry attempting this.

If you are going to power your lights off the power supply, you might as well power your P360s off of it as well.

1) Will a 300watt power supply be enough?
    (OR should I go with a 550watt power supply)

2)How do I take power from the power supply and use it to run the P360's and the lights?

You need to add up the draw on all the devices, and give yourself some headroom.
With LEDs you should be fine, but incandescent lights may depend on the wattage.

They make pass-through adapters for case fans that will plug into the molex connectors on the power supply, and have a pigtail for the fan on the other end.
That would be the easiest way.
You could also cut the molex connector off of a set of the extra wires--provided you have an extra connector in your case.
