Added a couple extra things and now my PC won't boot.

So I put an AIO in my computer, added some rgb fans and an nzxt hue+ and USB hub. My PC booted perfectly before, and now all the rgb stuff flashes for about 1 second before shutting off, and it's been on for about 3 seconds at the longest. I'm about 95% sure my 750w PSU is good enough and I can't figure out what else I need to do.
