CPU : i7 4770K
RAM : 16 GB DDR3 at 1600Mhz
MOTHERBOARD : Sabertooth z87

Wondering between MSI GTX N770 or MSI GTX N780.
The 770 is recomended with 550W Seasonic and I'm not sure if it is enough for the 780 which I want and prefer the most!

for a GTX 780 600W is perfect. for what you'll pay for a for a 550 (look for a 600-620 equivalent Bronze certified) and of course check the warranty (4+ years at least)

Yes a G-550 is plenty for a GTX 780..Plenty! - especially on a Haswell i 7 CPU.

(Call me crazy...)
I run a EVGA Superclocked GTX 760 on the small Seasonic G-360. (needed a 2x molex to 1xPCI-E 8 adaptor)
System:
i7-2600 (*Lowpower OC to 4.2 GHz w slight lowered Vcore) 8GB DDR3-1600, and just one 1TB Samsung 240EVO SSD. (No HDD)

Typical high gaming/graphics load is measured 220-250W on the PSU input (=max 225W on the PSU output)

Rock stable so far. Furmark and 3dMARK11 (Extreme) testet.
30Amps on one 12V rail on that little thing :)

Yeah I hoped in that!

Made a test where it shows that it has 450 power consumption with i7 4770K and 780 GTX ( OC )
