Does it provide 4 PCI-E power connectors? That's the big question.

It might be enough, but I'd go higher since I've never heard of the InWin brand.  While the minimum power supply for a pair of GTX 260 cards in SLI is only a 600W with 40A on the combined +12V rails, most sites recommend going higher, especially with beefier CPUs like the Core i7 now commonplace.

The calculator at SLIzone only lists a couple of 750W or lower models, the overwhelming majority of recommended power supplies are 800W and higher.

nope.its only enough to run one single gtx260 core 216.if u want to run it in 2-way SLI u need at least 850W power supply but it depends on how much amperage your PSU can supply.u may not need that much wattage.3-way SLI?1000W PSU recommended.

yeah i7s are very power hungry they can draw up too 200W but it should be fine you may need to go up to 850w for two graphics cards if you ever get a second
