600 PSU and SLI build enough juice?

[Frederik Andersen]

Hi my fellow hardware friends.

I have a problem with the power consumption of my PC.
(running it with one GPU is not a problem).

My spec's
Intel I7-4770K (100W?)
Asus Maximus VI Hero (Watt's unknown)
Samsung 850 Pro SSD (3,5W)
Asus DVD burner
Asus GTX780-DC2OC-3GD5 (Asus said 300W pr card which is kinda high?)
https://www.asus.com/dk/Graphics-Cards/GTX780DC2OC3GD5/specifications/

16GB Corsair Vengeance Pro series 16GB (Watt's unknown)
PSU Seasonic SS-600HT Active PFC F3. (600W)
+ the usual mouse, keyboard and small stuff via USB.

NOW HERE COMES THE QUESTION

I've bought one more Asus GTX780-DC2OC-3GD5, and want to go SLI.
According to my calculations the system requires at least 760W to run.

Is this correct?

And if thats the case, what PSU should i buy then?
(NO CHEAP STUFF)

An evga B2 or G2 850w would probably be a suitable choice, for you, the 1000w for overclocking headroom maybe. The gtx 780 is a 250w card, at minimum. You can use PCpartpicker to get a decent wattage estimate. http://pcpartpicker.com/parts/partlist/

i think you are right.
gonna look at the 1000w version, and find the best one.
Thanks for the fast answer

Evga G2 or P2 1000w are great units with 10yr warranty.

I replaced a several month old corsair 750w with an evga g2 with a 10 year warranty and it solved all my pc's problems, when looking at PSU's avoid looking at wattage as they can be extremely misleading, look at warranty periods as they are the best indicator of a decent PSU that will last
