Need some help regarding my PSU and GPU

Hi!

So I am buying a new GPU soon which is a GTX 760 windforce. And I have some doubts with this move.
I will first list my whole rig here so it would be known what my power draw is:

* CPU: i5 Haswell 4570 - 3.2 GHz
* MOBO: Asus B85-plus
* GPU: Currently a HD 5770 and soon hopefully a GTX 760
* 2 regular fans and 2 LED fans
* 1 HDD, 7200 RPM.
* Maybe a DVD rom in feature and a Fan controller

All of this is supported by a Enermax triathlon 550 W modular PSU. Link

Now first of all I would like to be again 100% sure that this PSU will be actually able to support my rig even at full power. (I will not be doing any kind of OC)

Here is a picture of some specs about the PSU (I am not that good at reading out if it's got enought A for the new GPU :/)

And now secondly... If the PSU indeed is able to support all of what I have in this rig.. I have some questions about connecting it.
I have two rails or connections or however you call them on PSU that support the 12V GPU products. And for them I have two cables.

Now as you can see, the first cable nr 1 has only one connector and the second one nr 2 has two of them in one. So if I connect the second one to one rail, I could connect like 2 HD 5770's to it.

But I am wondering that If I get that GTX card now, how am I supposed to connect it`? It requires one 8 pin connector and 1 6 pin connector.

So can I just take the one cable (figure 2 on the second picture) and connect it to the card. Or do I have to take both of thoes cables and connect the single on to the GPU and then only one of the connectors from the other one?

Thanks in advance,

Veske


Edit: Seems that the forums picture attach function does not want to show dropbox pictures... Just pasted links instead.

the psu would be able to support your build, but not optimal for dual 5770's. For dual 5770's you would need a 600 PSU according to http://www.newegg.com/Product/Product.aspx?Item=N82E16814102858

the 760 is a very efficient card with a max draw of 160w

Your gfx card will supply extra dongles to make it work. Look at the pictures.

if you go the dual route the care will still supply extra connectors, but you would have to upgrade your psu to at least 600

The one wire that has two of thoes 8 pin connectors seems like the best choice but I am just thinking that the PSU probably is not that smart to like move some A from the other rail to the one I use as the GPU requires 30 A atleast and one rail has 25 A.

But am I wrong or?

When you purchase your new 760 it should come with the appropriate connectors and there are like hundreds of youtube videos that show how if you're really not sure. Trying to explain these thing verbally is not very efficient. Try looking up a vid it will help avoid mistakes by seeing what you're doing.

So noone who could anwser it? I would just like to know if I can use just the one cable which is nr 2 on the second picture. Or do I have to put two seperate cables into the PSU which will make my cable management a lot harder.
