I have a 390w PSU (a prebuilt dell pc), so in fear that it can't power my gtx 1060, I bought a Shark atx-650-n12s PSU without thinking. Now my question is, will it be enough for at least a month or 2?
System specs:
i3 4150
8GB DDR3
1TB HDD
Gtx 1060 FE

Edit: I know my CPU would be a bottleneck, so I am buying new mobo, CPU and ram soon.
