I am building a new computer and am not sure what size of power supply I am going to need so hopefully you can help me out.

Here are the components that I will be ordering:

Motherboard: ASUS SABERTOOTH 990FX R2.0 AM3+ AMD 990FX SATA 6Gb/s USB 3.0 ATX AMD Motherboard with UEFI BIOS

CPU: AMD FX-8350 Vishera 4.0GHz (4.2GHz Turbo) Socket AM3+ 125W Eight-Core Desktop Processor FD8350FRHKBOX

Video Cards: 2X EVGA SuperClocked 02G-P4-2765-KR GeForce GTX 760 2GB 256-bit GDDR5 PCI Express 3.0 SLI Support w/ EVGA ACX Cooler

Memory: (2X for a total of 16GB) G.SKILL Sniper Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900) Desktop Memory Model F3-14900CL9D-8GBSR

Not sure how much hard drives and CD drives affect what size of power supply you need so if you want me to post those details let me know.

A quality 650w PSU should be fine. If you want some more headroom a 750w would be more than enough. (Overkill)
 
Nvidia recommends 700 watts for GTX 760 SLI.

I figured figuring the TDP on the GPUs + CPUs and seeing some charts it would be enough.

a system equipped with Intel Core i7-3960X, ASUS P9X79 Deluxe, 16GB Corsair 1866MHz etc etc, and SLI 760, consume 520 watt in gaming mode..

Going with 750w won't hurt either I guess you can say.
 
Hard drive power consumption is negligible, and is even lower if you go with SSDs. Speaking of which, you should really add one to that parts list if you can, it increases overall system speed and responsiveness versus a HDD by a very noticeable amount.
