Try it. Get one of these wattage counters and measure how much your system draws under load by prim95 and MSI combustor. If it comes close to what your PSU can deliver, you are probably bottlenecking it. If it comes to like 350W, you're fine. I'm talking about when the 780 is already installed of course.

who cares...

You may be fine running your setup with a GTX780 SuperClocked but it's hard to say without knowing the model PSU you have.

550w is fine, depending on the model and maker. It's not about the wattage it's about the amperage on the 12v rail.

 

Remember - 550w is the total PSU output, and that includes the 5v and 3.3v rails !

 

However with a decent solid PSU you will be fine. You don't mention what PSU you have so it's kinda hard.

That PSU line came out exactly a month and one day after I ordered mine. I was so mad.

Is it a 3770k? You have a non-K processor listed, but a Z77 motherboard. 

Nvidia recommand a minimum of 600W for a 780 system, so you should get at least 650W.

 

Nvidia massively exaggerate it because of people's insistence on using shit power supplies.

550W can work but it depends on the specific power supply model.  Lower quality power supplies are often not actually capable of their rated wattage, hence the need for NVIDIA to be very conservative with their recommendations (that, and they don't know what the rest of your system is).

 

The system will probably consume around 400W-450W on fully load if you don't overclock anything.  And you probably shouldn't, running a power supply near its max load is not really good for it.

Power supplies also tend to degrade with time and high use so after a while you probably wont get the same wattage as you did out of the box, not to mention whether the power is clean or not.

You're a little bit off.  MAX TDP of a 780 is 300W in theory but NVIdia capped it at 275W (overclocked).  CPU appears to be locked to 77w.  I'd say 350W under 90% load, 400w if overclocked

 

I have a 450 watt powering my 660 but its fine, you should have at least a 700 watt psu 

700W for what?  You could power 2 780's at stock with an I7-4770.
