So I bought this parts for my new rig. After building it, i tried to power it up and install OS. While installing the OS, it unexpectedly reboots and it always do. When I've succesfully installed my OS already and using my computer, it still automatically reboots. It's like my video card is having problem spinning whenever it reboot. Is my PSU faulty that it does not supply enough power on my video card?

If you have an older video card, swap it with the 7870 and see if it solves your issue.
If it still happens then it "might"be your PSU.

[EDIT] If you have OC'ed your mobo, reset all back to default, might be something wonkey in there.
