Help selecting a PSU for 660ti

[qwiksilvertrav]

I know, probably a TON of threads on this and sorry.
I just picked up my GTX 660ti and looking to replace this old OEM 350w power supply with something good. I'm thinking about 750w so I have some headroom for future upgrades.
Right now I"m running a Core 2 Qaud along with the 660ti.
I'm not in need of the best PS money can buy. And not to worried about noise either. I just want something that'll be reliable and put out the rated 750w. I also want something that is SLI compatible as I plan on adding a 2nd 660ti down the road. I also plan on upgrading my proccesor and motherboard in the next few months too. Probably a Intel I7...
Thanks in advance

Oops forgot to mention I'm not really looking to spend over a 100.00 on a new power supply.

For a system using a single GeForce GTX 660 Ti graphics card NVIDIA specifies a minimum of a 450 Watt or greater power supply that has a combined +12 Volt continuous current rating of 24 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors.

For a system using two GeForce GTX 660 Ti graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 650 Watt or greater power supply that has a combined +12 Volt continuous current rating of 38 Amps or greater and that has at least four 6-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) @ 45-50°C ambient temperature, is the most important factor.

All of the following power supply units have a more than sufficient combined +12 Volt continuous current rating and have at least four PCI Express supplementary power connectors to power a system with two GeForce GTX 660 Ti graphics cards in 2-way SLI mode:

Thanks for the good summary. I think I'm going to go with Rosewill CAPSTONE Series CAPSTONE-650-M 650W Power Supply. Looks nice and efficient and has everything I'd want for just under a 100 bucks. Good reviews on it to boot.

Make sure that the CAPSTONE-650-M will fit into your case before you order it.

Your OEM power supply is most likely the ATX standard 5.5" (140mm) in depth.

The CAPSTONE-650-M is 6.42" (163mm) in depth.

I checked my case and it looks like it will JUST fit. Right now the current PS has about an inch of clearance behind it so I'll be cutting it close. I think it'll fit perfectly though. Thanks for your help!
