Just wanted to report a seemingly rare issue I've encountered, I've found one other who has an 850 P2 on the NCIX reviews with the issue, and a mention on forums.overclockers.co.uk. 
You can find others with the issue if you search well.
 
The fan while in Eco Mode will get into an idle state and become stuck there, and over a very short period of time with my rig (4690k GTX 970) in benchmarks such as Unigine Valley or games like Witcher 3, the PSU will become overly hot and shut down the PC to prevent damage. 
Particularly the upper right corner of the exhaust/back (fan face down) of the 650 P2 gets very hot to the touch.
 
When the PC reboots from the unexpected shutdown, the fan will turn back on only until it is cool enough again to go idle, and again, become stuck idle.
I've monitored this with the case on its side, viewing the fan as benchmarks and sudden reboots occur. The rear of the PSU gradually builds heat which is noticeable to the touch.
I don't have any precise measurement tools to give anything conclusive.
 
I just hope it truly does shut down before damage can occur, and that my PSU and other components are not damaged. 
I seem to be very unlucky by getting this PSU with this rare issue, though I know I'm not the only one.
 
The fan works, it spins, nothing is obstructing it, works even in Eco Mode after it overheats and reboots.
For some unknown reason once it gets back to an idle state, it will not spin again. 
That some sort of software issue or something? Since the fan is clearly functional, and at least after the reboot detects the temperatures since it spins.
 
I've yet to switch it to manual mode, but as with the 850 P2 user, I'm sure it will work just fine in that mode. 
It's unfortunate though since I got this PSU primarily because of the Tomshardware review detailing how insanely quiet it was... in Eco Mode... which is broken for me.
 
I would RMA, but it's too late to do so for NCIX since its been over 15 days now. I'm in Canada, and shipping to EVGA in the US is unfortunately a lot more timely and costly.
As long as manual mode functions properly I can still use my PC, and I suppose I have 10 years to change my mind... failed in not even 30 days...
 
I highly doubt there's a solution to this issue but if anyone has suggestions I'm all ears
Hopefully EVGA is aware of this issue and can do something to fix it for future customers

I always hated that ECO stuff and never used it. The PSU gets too hot before the fan decides it wants to run. I really think it is a bad idea and wish manufacturers would stop using it.

Depend of situation, Eco Mode is great if you use 200-300W stronger PSU than need, but if you buy exactly how much need or only 100W more than better leave fan enabled always. From other side that flat part of PSU serve similar to heatsink, and it's not weird to become hot when fan not work. On my Seasonic was constantly VERY hot on touch and fan spin very rear.

that's really strange situation, I've been using my EVGA 650 P2 in ECO mode since I bought it last year.
never had any issues nor I've ever heard the fan spinning at all.
I used it with Z97 system as well as now on Z170, I don't benchmark but play Witcher 3 as well.
I don't understand why the PSU should get that hot with 4690k + GTX970 while gaming.
does your case get very hot inside which maybe leads to overheating the PSU as well?

We even have the same case lol. Yes my case can get hot, but the issue is simply the PSU fan fails to turn on suddenly in Eco Mode, yet works fine in Manual mode.
Eco Mode simply broke somehow, even though the fan is still working, and Eco Mode worked for the past 25 days.

I registered it the day it arrived. The PSU works perfectly fine with Eco Mode disabled so far, as the fan actually spins so it doesn't overheat.
It appears to only be the Eco Mode setting which is broken, which I don't have to use.
So I think I'll just hold onto it instead of dealing with the hassle of RMA, but thanks for the help.
I have 9 years and 11 months of warranty left should I ever change my mind haha!

I know the selling point of ECO mode is 'silent' operation but is your fan really that loud? My fan in my SuperNOVA 1300 G2 runs all of the time and I can't even hear it.

It's not bad, but I can hear it at idle. It's definitely louder than my 3x Noctua NF-A14's and NH-U14S CPU Cooler. 
It's not so much how loud it is that is annoying, but how it sounds which is annoying. Suppose that's what the experts call its acoustic profile, not really a fan of it.
I'll never hear it while listening to something with headphones which is good enough, and when the PC is under load everything else becomes louder than the PSU fan anyway it seems.
GPU fans definitely enjoy getting loud under load.

I've seen some fans that had some weird shapes to their blades that did make a strange noise but I have nine 120mm fans running at 100% all of the time too that might be drowning out any noise my PSU fan is making.

Yeah it really depends on your rig. Mine is tuned for quietness prioritized over airflow (40% on my two front intake fans and CPU fan at idle) so my EVGA PSU's fan was the most audible for me. But for people who don't mind the noise or like to crank their fans for more performance it wont matter. Unfortunately my EVGA 1200 P2 developed a constant clicking noise with ECO mode, and the same happened with my replacement so I'm back to Corsair with 0 noise.

Re: EVGA 650 P2 Eco Mode is broken, which overheats and restarts PCs 2016/06/08 04:14:26 (permalink)
My fans are all pretty quiet. I have two Cougar high static pressure fans on the top 240 rad, three Noctua NF-F12 on the back Monsta 360 rad, two Cougar high air flow case fans on the bottom blowing up into the case and two lighted Corsair high air flow case fans in the front. They're really not at all that loud and I have them at 100% because I don't have any way to put a custom fan curve on them. My MSI Z97 Gaming 7 motherboard BIOS has two panels when entering a fan curve. One panel shows the CPU temp and the other shows Motherboard temp which I think means internal case temp but it doesn't seem to work as I think it should. I think I am only getting control from the CPU temps. One of these days I will finally get a fan controller with some temperature sensors for my case. If my PSU fan ever spins up and gets loud it is during a game and I can't hear it above the game's audio. These Bose Companion 3 speakers were a good investment. I think they have been on 24/7 since 2008 or so and never gave me problems...      yet.

Not the news I wanted to hear. I just purchased the 650 P2 psu tonight. I hope I don't run into this issue.

So I've started a cross ship RMA and EVGA is covering shipping both ways which is awesome!
I don't have to spend $30+ shipping something across the continent, and I don't have to go weeks with a non-functional PC because of the cross ship process.
 
Can't stand listening to this PSU fan at idle, it's too loud to always be running.
Under load other things will become louder than the PSU fan which is fine.

Yup...same problem...
 
I bought the 850w P2 and I'm guessing eco mode worked fine for the first 35 days since my system never crashed. Then suddenly this week whenever my system was under load (playing games or running Unigine Heaven) after 7-10 minutes the system would shut off and restart.
 
I tested everything (MB, CPU, GPU, RAM) all worked fine in my other system and when running software tests on them. Then I thought hmmm maybe the PSU is overheating so I tested again with eco on and just like you said after it goes idle the fan won't turn back on when it hits high temps. I just turned of eco mode and I have Unigine Heaven running for the past 2 hours with no crashes.
 
Such a bummer cause eco mode was completely silent when idle. Now it's just a really slight hum that's only noticeable when I pay close attention (it's summer in NY so my AC is on most of the day anyways so I can't hear the fan 98% of the time). If the fan noise annoys me I can always RMA during my lifetime. lol.

Maybe I should have made a special request for EVGA to test the replacement before they send it off.
Watch me get another with the same issue or something

Keep us updated! I don't think you should have a problem. I am sure tons of people use the eco feature and you see hardly any complaints. Its a feature designed and advertise to work. Which it should 100% and be able to trust it as well.

I got same problem with mine, P2 850w, over a month I had issues with it when gaming. Put it in an older system that draws more power and it starting rebooting very often. I turned off eco mode and seems ok now.

So apparently my replacement PSU went from California to Kentucky in the past 2 days, and claims to arrive on the 28th.
Maybe UPS should try sending the package North instead as far East as possible, might help it get to mid-west Canada.
Interesting detour...
 
Supposed to arrive tomorrow and it's still not even in Canada...
Meanwhile an order placed the other day on Newegg got from California to Canada in a day.
UPS seems stupid, it's like they're throwing darts at a map of the US.

So in the past 16 hours it made it through to 3 different cities in 3 different states and actually got here on time 
The new PSU is good so far, but so was my original for about 20 days, so lets hope this one stays working!
 
I ran the most power demanding benchmark that exists according to overclock.net, the FF Heavensward benchmark for about 30 minutes, and the fan never spun in Eco Mode.
So instead of waiting hours for my extremely air conditioned room to be hot enough, I got a hair dryer, and within a minute the fan started up and I stopped heating it.
My broken PSU overheated and shut off within minutes of running any benchmark in Eco Mode, and the fan never spun.
 
All is good, the fan starts before the PSU overheats.
I can enjoy a silent idle with my Noctua filled PC again, and my GTX 1070 arrives tomorrow!

Same problem here. My 650 P2 worked well for a couple of months and than it started rebooting in Eco mode. I just switched it to manual mode and its been fine since. I keep reading about EVGA quality but this my first product from them and it's not off to a good start. Hopefully I won't have any further problems.

I tried eco on/off. Honestly. The fan is so quiet. I cant even hear the thing running. Even under full load. I also remember reading I believe it was from Tom's Hardware or Jonnyguru reviews. The 750w version actually had a louder fan then the 650w version. The 650w version was much more quit by 10-11db or so. Either way. Good to see EVGA took care of you and are back up running!
