Will an Antec 1200 V3 be good enough to power 3 x EVGA GTX 570 in SLI?

I'm really confused

It is my understanding that the Antec 1200 V3 is a computer case that is sold without a power supply. For powering 3 cards I wouldn't scrimp and would go for something like this for my power supply: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Make sure your motherboard fully supports 3 way SLI.

Three 570's need about 60 amps. Figure another 10 amps for the CPU. That's about 840 watts right there. Figure another 100 - 150 watts for the rest of the system and you are up to about 1 kw. I'd select a 1200 watt PSU.

While I don't disagree that getting a 1200 watt would be playing it safe, Tom's had no trouble at all testing 3-way SLI and XFire on an overclocked SB platform with a 1kw PSU: http://www.tomshardware.com/reviews/crossfire-sli-3-way...

When they benchmark using a certain setup I usually trust that it's rock-solid stable.

What I meant is: Will an Antec 1200 V3 with its 8 fans be enough to keep 3 x SLI EVGA GTX 570 at a good temperature?

Depends on your motherboard. Which board do/will you have? The case should be fine, but if there isn't enough space between the slots, your cards will be hot and loud under load.
