Yes your PSU is enough for the gtx 980 .
The card has a max TDP of 165 watt and requires a 30 amps and a 500 watt PSU is recomended so the seasonic 620 is cool.
People always told me you need to calculate all of your parts needs and take a PSU according to that.
So with my processor and motherboard and everything, is it still enough for the card?
