I have a Sentey Extreme 550w psu and when I overclock my GPU or CPU they run cool but my games still crash, is it my psu that might be causing this to happen. I have an FX-6300 and an R7 260x.

It might be a power supply issue, BUT the real chance is you probably messed up your overclocking.
To boost CPU and GPU performance while keeping them stable, a bit more voltage is needed.
Higher voltage leads to higher temperatures.
Every CPU and GPU has a threshold beyond which it becomes unstable no matter the voltage.
If you approach this limit, your PC will crash frequently.

I've spent many years assembling PCs and have frequently questioned whether an ordinary person could verify this idea. I've never discovered one. PSU components are quite affordable, so trying another might reveal the truth. It could be weak VRMs on the motherboard.
Edit: The only alternative I can think of is using a system monitor with logging, then examining your voltage readings during operation for any drops or spikes. This might indicate a faulty PSU.

I have been building PC's for decades, and have often wondered if there is ANY way for an average person to test this theory. I've never found one. PSU's are relatively inexpensive parts. Try another one and you'll know. Could be wimpy VRMs on the motherboard.
Edit: The only other thing I can think of is to use a system monitor application with logging, then look at your voltage levels under load and look for drops or peaks. Might be an indicator of bad PSU.
When a cheap old PSU failed in an overclocked PC belonging to my daughter, I wondered if the new PSU would allow a higher overclock. It made no difference.
