Rosewill Hive 650W Enough to Run GTX 560Ti 448 SLI?

Hey just wondering if this PSU: http://www.newegg.com/Product/Product.aspx?Item=N82E16817182132 would be capable of running GTX 560Ti 448 in SLI? I've read some conflicting reports about running 560 Ti's SLI on 650W power supplies and would just like to get some community input on it.

    The 560-448 us basically a 570 w/ one SM unit disabled.

    According to nVidia, the 570 wants 550 watts for the 1st card and rest of system + 219 for the 2nd
  2. On second look the GTX 560 Ti 448 does not use quite as much power as a GTX 570 but it does use more than a GTX 560 Ti.

    You might want to go with 750 watts just to be sure. Guu3d recommends 750.

    Thanks to both of you for your answers. Anort3, you were right, for some reason I thought my 650 had enough of the PCI-E connectors with it but it didn't. I'll probably end up just not doing SLI then, thought about it because there was a nice 560 on eBay for a decent price but if I have to upgrade PSU in the process it would start getting to the range where I would probably be better off just picking up a 600 series card and forgetting about SLI altogether.
