That is the main difference.  The 1300G2 (and most of the 1st gen G2 PSUs) do not have ECO mode which is feature that allows the fan to power down when not needed.  1200 Plat is a little more efficient, but the 1300 is solid.

I too bought the 1300g2 in lieu of the 1200p2. But as soon as I received the in stock notification I bought the 1200. I will either sell the 1300g2 or stick it in another build. I got both at 50% off so I'm not heart broken. The month or so I had with the 1300 was great, very quite. Ran 2 980tis overclocked, d5 pump at 4, i5 3570k over clocked to 4.4, and 6 fans. Never broke a sweat. If you stick with the 1300g2 you'll be happy.

I went with the 1600 P2, only a 50 € difference in price and I didn't want to gamble with waiting on the 1200 P2.

You did, right in your post you said  "anyway fan not work"
 
What do you mean ?
You just flip it over.

Actually they are not white, they are more silver, EVGA should change the description.
They will look great with the Ti`s silver 

The 1200 will be here Friday, I`ll put the cables in then and post some pics 

Excellent, I wait to change platform to install them.
They are perfect, absolutely perfect, size, I mean thickness is perfect.
Why you use that wire from Cable Set Box? 
Use little velcro from 1200 P2 box, you got few of them.
They are excellent for that purpose... You can separate VGA from SATA and Molex and CPU/24pin... 15-20cm from connectors.
 
Your graphic cards are perfect too. 
They cry for water block. 
NVIDIA can make same design next 5 years and still people will love them.
 
 

That looks excellent Scott! I like the silver as you said, it matches GPU's and other components. Now I'm jealous!! lol That's the PSU I want. :)

Nice package and strong PSU box are very important... EVGA pay attention on that details except for motherboards boxes.
But I notice CORSAIR have very nice boxes design for all hardware, but not so durable paper is thin...
Example I look box of my Seasonic X-750, 4.5 years old and I several time install and reinstall PSU and put in box, remove cables, many time opened but after 4.5 years Seasonic box is still strong, not damaged, no traces of usage new and still keep smell on new stuff not so strong but like 5 months old... I don't know what is with Seasonic PSU boxes today... but CORSAIR and many other boxes are gently... and on many reviews new box looks older than my almost 5 years old Seasonic.
I had this PSU first model, from 2010, package was as I remove foil yesterday...cardbox is such quality that you can't damage that or can't lose shine and become dirty after many years.
 

 
 
I prefer zip ties over fat velcro, just my personal choice, I think it looks better, I still have to tidy them up, done for tonight 
 
OK if you prefer zip ties... I use them for other cables on back side, but velcro from 1200 P2 is not fat at all. 
I like and velco from Hybrid cooler... 
 

do you have ECO mode on?
 
according to EVGA the fan should spin to %100 only if you reach 65C inside the PSU.
that's not really easy so it shouldn't actually happen at all.
 
with the ECO mode on I never saw or hear my 750W G2's fan spin during the last 6 months.
