wdadws :
sorry , found new one http://pcpartpicker.com/p/3bmqe
Solid but overkill and also just not enough to add a 2nd 770 in it.
If you want to SLI them later i suggest one of these:

http://pcpartpicker.com/part/cooler-master-power-supply-rs850afbag1us
These 2 are enough for you to Overclock + Fill RAM + add more storage + add another 770
Later this year.
If you dont want to add another GPU down the road:

Also you really don't need Platinum. Those are overpriced and some Gold's work at a Platinum Cert.
Check the link i posted with the PSU tierlist.
Tier 1 / Tier 2 are good.
