Welcome to the realm of 1000watt power supplies. Not saying you absolutely have to have one, but to feed all your goodies with nice clean power, I would recommend it. It's not only the cards that need the juice.
I was looking the other day over at newegg. There was a BFG 850 watt that had gtx260 sli "ready"...... and somehow considering the rest of the stuff in my case, I didn't think it was enough.
check in the card's specs the Amps needed it says 38A while my PSU has a single 60A rail... remember i want to sli them...
Just so you know, the card in the link is the original GTX 260 (not the Core 216). I just want to make sure you don't get that card thinking it's the Core 216. The old one's still good, though (within 10% of the performance).
The PCP&C 750W PSU will work fine. Invisik will be probably around soon to brag about how his GTX 260 SLI and overclocked Q6600 can run on a 500W Antec PSU (I'm hatin' 'cause I'm jealous ). The thing to remember is that the 38A requirement is for the entire system, not just the card by itself.
that psu is plenty im running 2 gtx260 oc with a quad oc @ 3.2ghz all running on a 500w. so its safe to say 750w is plenty. In my opinion i would get the regular gtx260 since they dont perform much different then the gtx260 216sp. save some money, or use it for more ram.

Avenger_K u saw that coming lol. oh ya more good news i manged to hook up a another card a 9600gso for dedicated physx. so im able to pull 3 cards off with my 500w. oh ya i heavily oc that physx card too. But i removed it and put it back in my bros computer since 2 gtx260 is plenty and the 9600gso bottlenecks my gtx260 in ut3. xD

One thing, the old G260 is EOL, and newer 55nm chips will arrive soon, and theres price cuts coming on the 216s as well

As dishonest women often say: It´s not the size that counts, its how you use it....
In case of PSU's, it IS kind of true.
You can get a so called 850W-1000W PSU from any mickey-mouse brand, but the truth is, you will not be
getting that wattage in real life. Most of those no-name brand PSUs will choke with two GTX 260s even if they claim to support 800+ W.
In parts as critical as the power supply, don't skimp out. Go with reliable, fire tested brands like Antec, Thermaltake, BFG etc.
I have a Thermaltake 750W PSU with two GTXs 260 (BFG MAXCORE (216) OCX version) which consume as much power as a 280. The PSU feeds them the required juice without a hiccup. My case is also chock full of 100mm intake and outake fans, along with 5 hard drives and 2 DVD drives.
A basic but sure-proof way to determine the overall quality of a PSU, is to feel the weight.
The more weight they have, the more powerfull its output is. (this is related to the quantity and quality of heatsinks used in the PSU. As more wattage is provided, more heat is generated, thus the need for better cooling.)
