Wh at is the minimum amount of watts i need for 770

I am thinking fo upgrading to a 770 and dont know what the minimum amount of watts in my psu should be? My system specs are:


maximus vi hero

dvd drive

16 gb of ram 

some led strips

2 hdd

i currently have a 650 watt psu and dont know if that would be enough to handle the new upgrade. the help is much appreciated thanks.

400 to 450 minimum.

you could run it on a decent 500 watt but a 650 is fine I see on your profile you have a hx650 so you will have no problems doing that.
