Think I need to upgrade my power supply - what will be sufficient?

So fairly recently, I sold my two GTX 660's and upgraded to GTX 660TI's in SLI. I also decided to take advantage of my internal hard drive bays, and installed most of my hard drives inside my case. However, when gaming, my computer will randomly shut off and reboot. This hasn't happened under any other circumstances, and both of my cards are new and seem to be functioning so I believe the PSU is the issue. Below is a list of all the components it's running right now, if the PSU is insufficient like I think it is, what should I replace it with? If the PSU is sufficient what else could be causing the random shut downs during gaming?

i5 3570k 3.40Ghz (not OC'd)
4x 4GB 1866Mhz RAM
2x GTX 660Ti
1x GT 610
3x WD Caviar Green 2TB
1x WD Caviar Black 1TB
1x WD Caviar Green 800GB
1x WD Caviar Green 500GB
1x Samsung 840 Pro 128GB
1x LG Super Multi DVD RW drive

That covers the major stuff, nothing else of note I don't think. The power supply is a Corsair TX650M. Any help would be appreciated! Thanks

It's right on the edge in the power dept. a 750w would be better.

A 600watt is the minimum power requirement for 660 Ti's in SLI.
Get the 750watt as for future proofing sake if you plan to OC your cards and CPU

Why dont you try a modular seasonic PSU. I think that your computer shuts off because the new GPUs need more power so depending on how much money you will spend, I have a couple examples.
-SeaSonic SS-750KM3
-SeaSonic M12II

Yes, but that PSU isn't available in most places online and is discontinued so he wont have enough time to buy one before they sell out.
