The problem with that though is that I need to connect my iphone to the computer to sync and stuff. I really feel like this is a software problem, maybe some conflicting drivers or something. I mean I have a 650w psu so that shouldn't be the issue.

I mean I have a 650w psu so that shouldn't be the issue.

I am not suggesting it is drawing too much power for the PSU, I am suggesting it may be drawing too much current for the USB controller for that USB port. For USB 2.0 that is 500mA maximum and for USB 3.0, it is 900mA @ 5V. That normally is a decent amount for typically USB devices but an iPhone may be pushing that. Also note that on many motherboards today, not all of the USB ports are 3.0. So try a different USB pair. And, as mentioned above, a self-powered hub may still be the best option. A hub that has its own power supply will use the computer's USB port for data only.

And in case it is a software problem, make sure you have the latest drivers from Apple.

You might also try connecting your iPhone to another computer and see what happens.
