Extruder stuck at 167 C

I have an i3 Prusa that i just finished building and I think the power supply is crap. It only outputs 10.75 Volts and that's after i tried to adjust it with the set screw. When I attempted to do a test print the extruder couldn't heat above 167, it would bounce around 165.5 to 167.0 while the target temperature was set to 200.

just checked the voltage to the print head, its only 8.5 V

Any ideas?

Fixed, kind of

Still think the underwhelming power supply is a problem but by increasing the distance of the hot end from my bowden style print head I was able to get it up to temp
