What is the rest of the system? If you have a CPU that takes 100+ Watts from the 12V rail and 4 RAM sticks of 1.5V (which is around 40W, maybe less) and a lot of other stuff, then it might not be enough. Also check which type of 750ti you want. Some of them require extra 6 pin cable.

You would want one without a 6 pin connector.

There is also a Zotac and PNY edition but I don't recommend those brands. Had too many problems. There is an MSI edition but it requires more power than the EVGA version and a 400W PSU minimum.

There is no "6 pin" free version from Asus or Gigabyte that I find in stock.

I strongly recommend going with the EVGA edition. It will be just as strong as the MSI but power requirements are a bit lower.
