Jumper cable connector melting

It has to be connected to the PC because I need to be sending the colors for the LEDs from the PC (a lot, they respond to what's on the TV/PC when I'm watching a movie/show so they should be as smooth as possible, which is a lot of data, hence my inital upping the baud rate).

Ok, so if it fits my price range and size requirements, any 1000uF capacitor is fine?
