in my current pc i have a gt 610 and a 300 watt power supply ive just upgraded to a 750ti and ive had a 500 watt power supply still in the box so i decided to get it out and install but there a small dent on the top right above all the wires coming out of the pcu the dent is very small in the corner where the factory binded it together or something like that so do you think that its a bad idea to install the psu. If it is will a 750ti run on 300 watt?
