Power supply and sli

Hi there, so I'm new to PC gaming and have recently completed my first build as follows:
Case: Corsair Carbide 400r
Motherboard: Gigabyte GA-Z77X-UD5H
CPU: Intel i5 3570K
GPU: MSI GTX 660 TI Power Edition
RAM: G Skill Ripjaws 8GB (2x4)
SSD: Crucial M4 128GB
HDD: Western Digital Black 1TB
Optical Drive: Asus 24x CD/DVD
Power Supply: Corsair tx650 v2

So my question is if I decide to add another msi gtx 660 ti in SLI will my current power supply be enough or should I go up to 750w or 850w.

Thanks in advance for any answers as I said I'm new to this so any help would be appreciated.

    You are good to go. Your system now takes 250W in full stress. Adding another 660ti (aprox 134W stress) will not force you to buy new PSU.

    Cheers.
