My current rig is as follows:
i5 3570k cpu (usually at stock speed, but I plan on OC'ing more soon)
MSI Z77a G41 mobo
MSI Twin Frozr 7850 2GB gpu
16GB Ripjaws 1600 ram
Rosewill 630W 80+ Bronze psu

I've had this set up for a little over a year now. It doesn't get used all the time, but I do use it regularly. When I am not actively using it, I either keep it in sleep or turned off (usually in sleep).
A couple resources online recommended a psu around 600w. Since mine is over a year old and right in that recommended area, I'm thinking it might be good to upgrade the psu along with the graphics card. If I go with a GTX 770, would it be wise to upgrade my power supply as well? Or would that just be unnecessary?

I feel like a bit of a noob, but: on the product page (http://www.newegg.com/Product/Product.aspx?Item=N82E16817182200) it says the PSU has a single 12v rail. Am I missing something showing the other 12v rails in the supply? Sorry, I want to learn this stuff myself so I can answer my own questions about it without bothering others.
