Rig upgrade, need advice/help.

So my problem is, I found a Palit GTX 770 2GB (not the Jetstream) for 760 money, but I don't know if my PSU is enough to power it. My system specs are:
CPU: i3-3220
MB: AsRock B75 Pro3-M
RAM: 2x 4GB Kingston Hypr-X Predator
SSD: 60 GB SanDisk
HDD: 1 TB WD Green
PSU: Corsair CX500M
Cooler: CM Seidon 120M

Unfortunately I cant afford both the card and new PSU.

if your running 1 card then yes you have enough power

Thanks for the help.

at most you would probs be pulling 400W so plenty of headroom on my 780 with a minor OC and my Cpu OCed plus drives etc im pulling 360 through the wall but my PSU is a little more efficient so i added a bit

It's more than enough read that; 780 Ti and 4670K maxed at 400w

3960X overclocked to 4.6GHz, with an AMD 280X only pulled a maximum of 434w

The only thing that bothers me is that I read somewhere, that 770 needs 42A and my psu, according to some site, whicha I don't remember, puts 37A or something on the 12V rail, I honestly don't know and understand nothing about electronics and electricity. Also it is realy hard to find any review about the card itself, I only find reviews about the JetStream verion . Any thoughts?
