Is there any way to plug the HD 7770 to this thing?
Yes if using a molex to 6pin connector like this:
Do some video cards come with this converter?
Depends on specific card, but some 7770 cards do come with it. What brand and series is your PSU anyway? Even with this converter plugged in, your PSU might not handle it well if its wattage is low.
