I am planning to upgrade my custom pc to :
I7 3770
NVidia 770
8g corsair ram
1tb hdd
Asus h81m plus motherboard
What recommended power supply would I need to power it?
 


what really matters is how much amperage is on the 12v rail. the 3770 will pull 10amps on its worst day. the 770 will pull 24amps with an extreme overclock under water. the xfx 550w power supply has a single 12v rail rated at 44amps... far more than you need.
