Hello I have a issue.. I was given a 1050ti to replace my 520 the only issue im running into is my computer doesn't have a 6 prong power supply cord in it.. and the power supply in my computer is only 220w what would be the best way to be able to run the 1050? If I need a new power supply what one would be the best? And do I have to do anything special to change the power supply or can I just plug it in and go? Please let me know I'm semi new to computer building/changing
