Yes should work fine has a 20+4pin and a 4+4pin (you may have to seperate the 4+4 pin but thats where your 4pin will be).. Also may a recommend another alternative if you would like one with a 4 year warranty for around the same price seasonic has done me great with this exact same power supply and is currently on sale: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
My apologies comes with 5 year warranty.. I have heard antec is good though so its up to you! but would definetly look into the seasonic as it comes with the warranty for free and antec's doesnt
my apologies again the antec does come with a limited 3 year warranty! just saw the 9.99 for the one year warranty underneath it. so really its up to you both are very similar and decent brands. my apologies for the mis-information
Thanks for the help guys. I am figuring that 520 should be fine for a GTX 460 or 560 with an AMD tri core. I looked around and it seems it should do the job. It also comes with the required connectors.
