New vid card and power supp

[ThatGoonGuy]

Im getting a gtx 970 4gb and i have a 500 WATT but i think i can stick with that because that what the site said ( min 500 watt power supply ) but if anyone knows what power supply i can get for like under 100$ please link it for me !!!
also make sure it has enuf spots for the vid card. i myself dont even know how many ports it will need to have (Power Supp)
