I just upgraded from i5-4460 to i7-4690k and my computer kept randomly rebooting (after a few minutes of run time). Then I started looking online (on my phone), and I realized that my PC needs 675W and for almost a year it has been running on 550W. Are there any bad effects that wi come from this? Also, how did it even function?
Just realized I've been running on super low PSU

Full system specs? Make and model of the current psu? You haven't provided enough information to provide an informed answer.

How old is the psu? It uses some very poor capacitors jg have them a life expectancy of 2yrs.

If those are failing it could be causing the shutdown issue.
You should also check cpu and gpu temps to make sure its not an overheating issue.

Good point, I mixed this up with a different model. Makes sense especially if the CPU and GPU are not overheating.
Either way wattage wise, only need about 450-500. a good 550w replacement would be fine.

Enter the bios after it restarts and see what it reads. Also try leaving that bios screen open for several minutes and see if the temp climbs or if it shutsdown.
As requested, I have run the BIOS for a good bit of time to see the CPU temp. It never crashed, but the temp got up to 47 Celsius. And seemed to be slowly rising. I then set the CPU fan to full power (at any temp) and it began very slowly lowering the temperature, though at first I barely noticed. Should I use a different fan/heatsink? I still have the old one.

First - go into your system settings and tun OFF 'restart on error' that way if the restart is due to a bluescreen error, you will see the error.
if you DONT get a bluescreen error, then you may need to re-apply the thermal paste from upgrading your CPU

For windows 7 (since its what im running here)
start menu -> my computer
RIGHT click on my computer -> properties -> advanced System settings -> Advanced Tab -> "startup and recovery" (its on the bottom section)
in that tab just below the center will be a check box "Automatically restart' UN-check that and then press 'ok' on all he dialogs you opened.
win8/10 should be very similar
if its already un-checked then its some other hardware problem. Try safe mode as suggested by @bignastyid and see if it stays on longer
