What power supply and cables do i need?

Solution
GTX 750ti is a very energy efficient gfx card based on the new Maxwell architecture. U can go for a 500W PSU considering u may upgrade ur hardware in the future, but u can easily choose a 450W as well, it won't harm. But do make sure u choose from good brands like Seasonic, Antec, Corsair and Cooler Master. Hope that helps.

No you don't. You get an overestimate, and even then knowing the required wattage is not enough for picking a PSU. What voltages certain components use play a role, as well as the fact that one should never buy a PSU off just labelled wattage.

Also, it's usually a peak load scenario what these calculators exemplify, whereas continuous load is much lower. Peak load, or brief spikes in power requirements, can be absorbed by the components of a quality power supply without a problem.
