PC reboots when playing games

[ShadowDragon101]

So I have a Dell Studio XPS with a Seasonic PSU and a RX470. I just recently replaced the PSU with Seasonic since my monitor was giving no signal during games. Now instead my PC is rebooting during gaming. I doubt the problem is the PSU, any way to see where the problem lies?

check your drivers for your gpu make sure theyre all up to date. also seeing how you got a new psu are you sure it can handle what your powering with it? coolermaster has a gool on their website that is good for determining how big of a psu you need.
