I was wondering if it's safe to SLI 2 of the GTX580 or that's just too risky.
System might hang or not even boot up since I don't have enough juice to power them up

And I have a 750W XFX Power Supply (not some generic one)

The 750W XFX power supply may be enough to power two of the 580's but I recommend something like an 850W for just a little bit extra power (these things can reach over 900W when overclocked and these cards have high power consumption, best to be safe.); you don't want your 750W power supply to shut down due to it not having enough power would you.

Just to be on the safe side, go for something more powerful. Because those cards are quite power hungry. 

Along with that, you'll probably have some extra hardware.

If you upgrade components  often i will go with 1,000 watts and up :) future proof ...

Max power consumption is about 300W for the card, 400 to 450 with the rest of the system, maybe even 500W. 750W just will not cut it. Sorry bud.
