430W PSU enough for a R9 280x?

[SuperChil]

I have used a PSU calculator and with the components I have plus the the 280x it states I will only require about 320W. I currently have a Corsair 80+ Bronze 430W PSU and I was wondering if it will be enough for the GPU?
My system
Core i5 4570
64GB Sandisk SSD
1 TB WD Cavier Blue
Gigabyte h87n-wifi
No optical drives
2 case fans

Although I do know I will need an extra 8 pin connector I figured I could use the one provide with the card?

You should use something above 500 watts. That will be sufficient for the GPU, CPU, Fans, and a few nice little LED fans or strips.
