[asniex]

nvidia gtx 660 Ti SC +
16gb corsair vengeance might upgrade in future
2tb seagate 5400 HDD + 80GB HDD
Stock intel fan and 2 x 120mm fans.
In the future I might add a Corsair H100
Should I get a 650W..? is it too much or less ?
I am gonna get a corsair TX series as it is cheap and silent. Please suggest me guys.
And I also have 3 intel mobos and 2xP4 , core 2 duo processor what PSU's should i get I wanna use them for creating a small render farm
Should i get individual PSUs or Can i get a 800w+ and connect all three ?

Bupming the thread up. I need to buy the PSU quick.

A Corsair TX series PSU will be more than adequate. As for the wattage, it all depends on what you're planning on doing in the future. Will you be doing a SLI/Crossfire configuration? If not, then a 650W PSU will be more than enough. Keep in mind that as the years go by PC components are becoming more energy efficient. If you're planning on getting a second GTX 660 Ti, then a 750W and up is what you'll need. For your second question about your 3 Intel Mobos, I'm not sure what to tell you. But my gut tells me that it'll be best to get indivual PSU's. Don't quote me on that though. Good luck!

There's not enough connections on one PSU , you will need three to farm.

Get an 850W + PSU to give you more headroom.
