You probably won't need more than 550W, but I would suggest getting a 750W or 850W PSU so that you can SLI in the future if you want.

Don't go below 650W if you are planning on OC'ing

750w is the safest.

maybe if he is going to sli, but 500w is fine for a titan and an i5 so 600 is good for a 760

Titan uses 310W alone under load.

For a system using a single GeForce GTX 760 graphics card NVIDIA specifies a minimum of a 500 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 30 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors. Some of the GeForce GTX 760 cards have a single 8-pin or two 8-pin or one 6-pin and one 8-pin PCI Express supplementary power connectors.

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

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

Wow thank you for the answers and the laughs hahaha. Thank you all for the answers. Also for the people asking if I will be using SLI I really don't think I will be doing that since it's not something I'm into /:. Maybe in the future but I've decided to get a 750W PSU and I will take some of the ones you guys posted into consideration :). Especially the 1600W one.
