Not enough.
The psu is mostly determined by the graphics card.
You are looking at 430w for GTX960 or 500w for GTX970.

Of equal, or perhaps more importance is the quality of the psu.
Look for a tier 1 or 2 unit from this list:

I have no problem overprovisioning a PSU a bit. Say 20%.
It will run cooler, quieter, and more efficiently in the middle third of it's range.
A PSU will only use the wattage demanded of it, regardless of it's max capability.
A graphics card upgrade would then be seamless.

Hope I did this right. This is the best power supply option I could find on that site ,while using Google translate.

This one works but translated into English.
