No, you should get a 650W+ from a reputable brand (corsair,seasonic,antec,xfx), preferably 700W+ so you have some headroom

all these will do the job fine and price is reasonable

here's a 750W if you afford it, it's the cheapest 750W i could find from a reputable brand but will give you plently of upgrade room

600W might work with a high quality PSU from a reputable brand, but your GPU use 299 (max) watt under load, adding another card will make it very tight on 600W and leave you with no headroom which you need for the rest of your system, you see? therefore 650W minimum, and your PSU aren't good, it works sure, but you need a high quality PSU to run your system especially if you wanna CF/SLI
