Just wondering if I will need a new power supply if I upgrade my GPU.

My current system:

FX-8350
MSI 970 Gaming Mobo
EVGA 750 Ti Sc 2GB
8 GB Ripjaws
CX430
WD 1TB and a WD 500GB

I want to upgrade to an MSI 960 4G, PCPartPicker says the 430 watt PSU would be able to handle it but I'm uncertain...given I would have very little headroom. I also have my CPU overclocked to 4.2 Ghz so that would draw a little more power as well. Just want to know if my CX430 would be capable or if I should get something with 500 or 600 watts. Thanks
