Ok, so here is my list so far:

- Intel E5-4650 (mostly standard, will do a light OC)
- Asus P9X79-E WS motherboard
- 16 or 32GB RAM
- (2x) Nvidia 770 in SLI


Power supply must be a 80 plus Platinum. I want to make sure that there is enough power for CPU, case, and a few other fans or coolers.

850-900 watts would be good, but you can't overclock a non-K intel CPU. You should get an other CPU since the motherboard is not compatible with this socket.

Yes, it is a Xeon E5-4650. So let's say it won't over clock, and it is compatible with the mobo (see link: http://www.cpubenchmark.net/cpu.php?cpu=Intel+Xeon+E5-4...) (At the bottom are links to others who have submitted benchmarks with that mobo), so i'm really looking at a base wattage of 850 with SLI. Is this correct?

The reason i'm looking at a Platinum is the efficiency of the PSU. Platinum is the top of the efficiency for these PSU's, gold is a little less, etc, etc. i don't build as often as i used to, and the CPU i was given, so i'm trying to use it with this build. Any advice is appreciated.

850watts is what is recommended for a system with 2 x GTX770 http://www.realhardtechx.com/index_archivos/Page362.htm Actual power consumption is a lot less here total system measured with a LGA 2011 6 core http://anandtech.com/show/7492/the-geforce-gtx-780-ti-r... So a quality 750watt would handle it. The difference between Gold and Platinum is so small that if you pay extra for the platinum then it will hardly pay back in savings on the electric bill.
