LED Cube...Help? Answered

So I made an LED cube. Forget programming I just wanted a cool home decoration. I plug it into a 5v supply and the LEDS aren't as bright as they would be individually hooked up. Can you help me solve this problem? I took out the resistors and it still isn't performing well. I have them in parallel. HELP!?
Thanks

You probably have too many for the transformer you are using.  It it getting hotter than it should?  A transformer can only supply a certain amount of current before it is overloaded and eventually burns out.

so 64 leds running at 75 amps each powered by a 360 amp 5v supply wont cut it? Any suggestions?

That's right.  You don't have nearly enough power to properly run 64 leds using 75 amps each.   You're going to need a war surplus search light generator or better to properly run that cube.

And personally I myself wouldn't want to be anywhere near and led that pulls 75 amps let alone 64 of them.  You better have a good welders shield handy.

Can you post a data sheet for the leds or at least check your numbers again please?
