Gtx 560 minimum power requirements

My thermaltake pure power np 500w runs my evga gtx 260 superclocked edition which requires a +12V current rating of 36 amps. The PSU specs say that I only have a combined 29 amps on the +12V rail. Its been running this way for 3 years with no problems what-so-ever My question is, will I be able to run an EVGA GTX 560 without any problems seeing as it requires less power or should I just upgrade my PSU to be safe?

    Since it ran the 260 it will run the 560. I suggest though replacing it with a better up to date PSU http://www.newegg.com/Product/Product.aspx?Item=N82E16817371016
