Need advice on PSU

[byomes]

Hello everyone I got a quick question for my gaming/3d rendering build. I was wondering how big of a power supply I need for the following components:

CPU: i7-3770k (paired with a corsair h50)
Mobo: ASRock z77 extreme6
Vid: EVGA gtx 670 2gb
RAM: Corsair Vengeance 2x8gb
HD: seagate barracuda 1tb 7200 rpm sata 6.0
SSD:samsung 830 128gb

Possible upgrades:
-Another SSD over 250gb
-gtx 680 SLI
-32gb of ram
-incase cooling fans, etc

***Was thinking about the corsair HX series HX750 12v 2.3

Thanks in advanced.

The HX shoul even handle your upgrades although SLI 2 x GTX680 recommends 800watts. http://www.realhardtechx.com/index_archivos/Page362.htm

For a system using two reference design GeForce GTX 680 graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 750 Watt or greater power supply that has a combined +12 Volt continuous current rating of 53 Amps or greater and that has at least four 6-pin PCI Express supplementary power connectors.

Some of the non-reference design GeForce GTX 680 graphics cards use one 6-pin and one 8-pin PCI Express supplementary power connectors because they consume slightly more power.

The Corsair HX Series HX750 750W (CP-9020031), with its combined +12 Volt continuous current rating of 62 Amps and with four (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with two GeForce GTX 680 in 2-way SLI mode.
