I currently have a 750W PSU and my current build is an AMD 8350 @ stock with a GTX 670. I am considering upgrading to a GTX 780 and overclocking my 8350, I was wondering if the 750W PSU will be enough to handle this change?

Thanks for the help in advance.

For a system using a single GeForce GTX 780 graphics card NVIDIA specifies a minimum of a 600 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 42 Amps or greater and that has at least one 6-pin and one 8-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) is the most critical factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

What's the brand and model of the 750W PSU?

It really depends on what 750w PSU you have. Just because it says 750w doesn't mean it's not a piece of junk. What's the make and model?

That's a poor quality PSU , with second rate capacitors.

Not the greatest, but it should run a GTX 670 or GTX 780 plus an overclocked 8350.

This. You might wanna go for an 850W PSU if you want more space to make improvements.
