No. Zotac lying to you. I'm sure they're in cahoots with the power supply manufacturers to trick you into thinking you need something when you don't.

Best solution

Depends on the quality of the power supply I upgraded from a 560 ti to a gtx 660 ti a while back and found out my power supply was 30$ on the net was a a 600 watt didn't hold up more then a day if you can link your PSU people will be able to assist you alot more easier

what really matter is how many amps it has on the 12v rail

so a good 500-600w+ psu will have about 40a on the 12v rail
12v X 40a = 480w with the rest being on different rails.

Bad psus will sometimes have 2 12v rails to make up the difference
12v X 20a + 12v X 20a= 480w but it is not the same since your gpu is only drawing from a single rail
