My new built PC crashes then restarts on its own while playing games. I think that the GPU is not getting enough power. If that's the case, is there any thing I could do to fix it? Like slightly undervolting the GPU?
The specs are:
TR2 600W PSU (the 12v rail is +12V1 23A and +12V2 20A)
MSI Z87-G41 PC Mate
EVGA Geforce GTX 660 (Requires 450 watt psu with a minimum of 24 amps on the +12 volt rail)
i5-4670k
8G ram (2 sticks)

Thanks for the help
-Joe

Too many possibilities. You will have to trouble shoot piece by piece; Its unlikely it is your power supply but it could be. Try switching the cables around, making sure the gpu power rail is not feeding everything else.
You want all that 23 amp 12v 1 rail on the graphics card.

It is enough. You can even run that setup on a solid 350w, you might got a lemon psu.

The psu has a PCI-E 6+2 pin and a PCI-E 6 pin on the same feeding cable. I'm not sure which is the +12V1 or the +12V2

How would I find this out?
