Nvidia recommend a minimum 500watt power supply for the GTX 750. If you are going to use another graphics card then check the manufactures web site for its power requirement.

Graphics cards generally require the most power of any component in a computer.

Caccy ? I read some where a PCI Slot can only give out 75 watts of power, there is no power lead on the NVIDIA GeForce GTX 750 Ti, it gets it`s power from the PCI Slot, so how can it require 500 watt PSU .

If you check the spec in your link it specifies 60W for the card and recommends a system power supply of minimum 300 watts so it is capable of drawing all of its power from the board.
