EVGA G2 Supernova 1300 Watt vs EVGA P2 1200 Watt (Vs Seasonic P-1200)
 
Hello, I was looking for some insight after looking into upgrading my power supply and I wanted to know just how comparable these two models are because the G2 Supernova is on sale at Newegg for the same price as a Seasonic Platinum 1200 watt. However, based on reviews and testing it sounds like the EVGA P2 outperforms the Seasonic, but the EVGA Platinum line is out of my upgrade budget. Other than things like Platinum vs Gold (obviously), fanless/hybrid vs semi-fanless, and overall efficiency/ripple resistance/ect., does the G2 have ALL Japanese capacitors now, is the soldering and construction about the same, and lastly, how is the semi-fanless noise for regular use (is it worth worrying over "fanless" vs "Semi-fanless?")? Otherwise, reviews at least seem to paint even the G2 as the closest thing to Platinum out there and a stellar product, but those little details were just hard to pin down because early reviews obviously don't account for changes made later like the possibility of the capacitors on the G2 possibly being 100% Japanese or not. It also sounds like from a noise perspective it goes P2 > Seasonic, but where does the G2's semi fanless mode place it roughly? Overall I'm digging everything else about the G2 from what I've researched, but further clarification would just help ease my mind. 
 
Any help would be greatly appreciated so thank you for your time EVGA community!

Thank you for the fast response! I figured as much about the the PSU fans vs case fans, but some reviewers can make a mountain out of a molehill when it comes to noise so I just wanted some more thoughts. After reading about the economy mode, though, it sounds like the fans don't necessarily kick on with the G2 unless it reaches a certain temperature, or am I mixing things up? A lot of customer reviews of G2 units mention the ECO mode, so I would assume that's what they were talking about.
 
Also, is it safe to say that the G2s now have 100% Japanese capacitors based on this thread here:  compared to the early reviews from Johnnyguru and the like? Otherwise, I'm really getting amped (no pun intended) about the Supernova G2 1300w; it might not be "Platinum," but dollar for dollar I'll take an extra 3 years of warranty over Seasonic, EVGA support/community, and an extra 100 watts of headroom if everything checks out.

It looks like as it is the P2 1200 thwomps the competition quite nicely going by this roundup -->
They also mention that at least the P2 is quieter than the Seasonic, so that's encouraging to read as well. I found it a bit disconcerting that I could not for the life of me find enough user reviews on the Seasonic p-1200, but the Supernova G2 by consensus reads a lot more clearly towards the positives without question.
 
Oh! Just remembered: Would the pins on the G2 1300 support my motherboard? I figure they should, but I don't want to punch the buy button and wind up having to hit it again for a new MOBO last minute heh heh!
 
**Side question unrelated to the others, but does anyone know if the American Express $25 off $200 Newegg promo through twitter appears on the statement itself because nothing comes off the bill when I put the card in for payment, even though I got the twitter confirmation from AMEX.

Just purchased a new 1300 G2  ( had to for the price )
 

I see I'm pretty much in minority with mine 1200 P2.
Probably because he is launched later.
Anyway whole SuperNOVA series is nice and we really no reason to think who will need less power AMD or NVIDIA.
There are models for every combination of graphic cards and processors. 

I liked full black more. That's one of reason why I choose Platinum.
You know for full black fit with everything. Even if you build black > silver only.
Even with black/red, anything. OK sleeve cables will be full black anyway but better and connectors black.
Platinum unit somehow fit best with Titan Black series, this new EVGA GTX980 with turbine. Probably and new NVIDIA reference.
Or GTX780Ti Classified... because everything is black.
Anyway I knew you and few people will upgrade soon on 1600 Titanium...

sigurkirs, even if you plan a second card 1200-1300W is way too much overkill.
my advise to you is, in case you sensider SLI, buy 850W G2 or 1000 P2 but not more.
the new generation graphics cards tend to use even less energy so you should be more than future proved.
 
I'll never understand why people tend to buy higher wattage PSU's than they need.
most buyer never really take into account what they actually need, pity.
so you are not alone Vlada011, I'm even more alone than you.
if EVGA had a 650W G2 or even 550W G2 I would buy it without thinking.
 
best example, you can run a high end GTX 780Ti rig with a 450W gold PSU perfectly fine.
I've never seen a single guy really doing it. why!?
 
here the proof from Tom Logan himself:

of course you can Vlada011, just watch Tom Logan's video I posted and decide yourself.
 
look at this test result and tell me why do I need more than 650W for a GTX 980 SLI!?
 
 

look at my previous post with the picture.

the difference is the efficiency, Platinum is about %3-4 more efficient than Gold.
1000 P2 is unfortunately the only option at EVGA if you want Platinum and not too much over kill.
I wish they would have also 850W, 750W and even 650W P2 models - would be great. 

I assume it's identical, been using my 750W G2 for over a week now and haven't heard the fan at all.
it's not surprising though if the fan doesn't spin under 370-380W so maybe my fan never spins.  

according to the 2 graphs the 1300W G2 has a more aggressive fan curve from %40 load on.
but on the other hand as it's wattage is higher it's more difficult to get there.
 
the graphs don't show the "eco mode on" but the "eco mode off", meaning the fan spins all the time.
that's why you have a noise level of 26dBA even at 0 load.
for the "eco mode on" the graph should be like that, zero noise until %40 load:
 

SuperNOVA 1000 P2 is same quality as 1200 P2 only 200W less.
That's enough and for SLI and for Intel Extreme Processors.
Jacob have I think 1000 P2 with GTX980 SLI or something like that.
Nice number 1KW PSU.

Well it's official: I am now the (soon to be) proud owner of a EVGA P2-1000 Watt Power Supply.  
I got an even better deal though because Newegg's stupid app kept crashing with Masterpass, so I found it for $10 cheaper and free shipping on NXICUS, got my $20 rebate, and even a $20 gift card promo for first time customer. 
 
Thanks for the help everyone; now I just have to wait until some really worthy GPU deals pop up. Here's hoping for a 990, TI card or something powerful for the New Year!

Just got the 1300 G2, with newegg's price I couldn't beat it. I told the other half that she didn't need to worry, I KNEW exactly what I wanted for Christmas . I have been looking for a new PSU so that I could finish my upgrades, and it's just what I needed to get everything rolling and working smoothly. I'm looking to get the GPU waterblock next week and then the case mods begin .
