Hello forum. I'm planning on doing an extensive gaming PC upgrade when Cyber Monday rolls around. I currently have a Corsair TX750 power supply. I'm just wondering if it can support 2 GTX 660 Ti's. I currently have an EVGA GeForce GTX 660 Ti (factory overclocked). I am planning on buying another GTX 660 Ti, regardless of manufacturer, and running it in SLI. I also plan to overclock my processor a bit more up to 4.2 GHz where it is at 4.0 GHz currently, purchase a simple 128 GB SSD, and add more RAM. If it is recommended to purchase a larger power supply, are there any cheap suggestions?
Please respond and thanks in advance.

The GTX 660ti is a 150W card. That relates to 12.5A on the +12V rail per card. You don't say which processor you plan on O/Cing, but even a 125W CPU would only draw about 10.5A maxed out. Allowing for other +12V components, I would say the Corsair TX750 80 PLUS BRONZE PSU with its 62A (+)12V rail will be quite sufficient. Previously, I used a Rosewill 750W PSU (62A +12V rail) on my 2nd machine with 2 x Twin Frozr 660 OC gfx cards with room to spare.

Run your system's specs thru a PSU calculator for an quick check: http://www.extreme.outervision.com/psucalculatorlite.js...

I currently own the i5-3570K processor overclocked at 4.0 GHz and plan on overclocking it more up to 4.2 GHz or maybe further depending on the CPU temperatures over extended periods of time. Thanks for the reply by the way. I deeply appreciate it and thanks for the advice.
