I have a really shady unbranded PSU that came with my computer that I've started adding new parts to. I added a fan via molex today. I've been using my computer for about half an hour, skyping and playing minecraft when my screen turned black and came back, twice. I do intend on upgrading the PSU when I have the money, I just can't do it now.
Am I overloading my PSU?

Is it just the screen doing weird things or is the whole system rebooting?
If the system is crashing/rebooting then yes, it does sound like a PSU problem. If your computer continues to work normally and it is only your display that appears to be losing sync, check system logs for GPU driver restarts which might indicate a problem with the GPU which might also be caused by the PSU. If the logs are clean, the problem might be the GPU's video outputs, the cable, the jack on the GPU or display, the display electronics or the display's power.

Well unfortunately I am back. I was watching a full screen twitch stream when my computer went black, the audio went out, and it seemed to freeze. My PSU wasn't acting up or anything, so I'm convinced it may be my GPU...
If this is the case, I have no idea what caused it.

That means his PSU is probably within ~5W of its current remaining power handling capacity before protection circuitry starts tripping... most likely an over-voltage protection shorting one of the rails to force the PSU to shut down by tripping input or output over-current protections.

Check your system event logs and see if the GPU drivers reported something.
Computers crashing when you start doing something more power-intensive than usual is often a PSU problem when the PSU has barely enough power output quality left in it to get you into Windows..
If you happen to have a multimeter with min/max function, you could connect that to the +12V rail and see what the min/max values are after your PC crashes. If OVP/OCP tripped, the multimeter might catch the spike or sag.
