Hi, I have a OC issue.

When i overclock my i7 7700k to 4.8 with xmp in bios (asus prime mb) my pc will reboot once every time i start it.
When running, it works all great.

What could be the problem?
650w 80+ gold
1080ti

when it restarts, does it show that the overclock is working?

Set menual voltage. Some of the chips not stable on 4.8

Did you check if your RAM is getting OC'd as well? Sometimes the RAM gets a boost to match the speeds of the CPU.
