Okay so here's the deal, the new GTX 750 Ti came out a few days ago and the price right now is 149.99 for the EVGA one. I saw the performance and it does a hell of a lot better than my GTX 660 1.5 GDDR5 OEM GPU. What my actual question is do I have to change my PSU? On Nvidia's website it said the minimum reccomended PSU is 300w and my PSU is at 430w. The reason I am asking this question is because I do not know if it will still work or need a replacement PSU.

Link to the product I want to buy:

Here are my PC specs:

CPU: i7-3770
R.A.M: 16Gb 1600 MHz
GPU: GTX 660 GDDR5 1.5 Gb
PSU: 430w
HDD: 2TB
ODD: Dvd Burner RW
O.S: Windows 8.1 64-Bit

Will I have enough headroom when I switch my GPU out for the new GTX 750 Ti?
Man if it doesn't. DAMNIT!

But, yeah there you go. All answers appreciated.
