Hi again - I wouldn't risk it, your PSU has 40 +12v amps and 42 is recommended for a system
with a gtx 780. Yes, there's a little headroom built in, but you should also be allowing some
xtra headroom for when the system gets stressed, OC, etc. You need more juice, so to speak.

Yes - most sites recommend the same power supply specs for a 770 as a 780, but the
770 does in fact use a little less, 35 +12v amps should cover a system with a 770
for gaming, 38 +12v amps or so if you stress it, and you have 40 +12v amps.
