I have 1200 P2 too but I don't know how to answer you.
I don't have such tools to check.
 
You say with Eco Mode Enabled, what happen when you disable Eco Mode?
I mean EVGA P2 is one of best PSU available on planet, looking performance, but looking whole package and compatible cables best without doubt, only T2 is above.

No I didn't have issue for now.
My fan no buzzing tone. I listen and before installation in case and after no noise.
I even looked one video where one guy record fan and increase volume on microphone only to present that Seasonic 1KW Platinum is more silent. But I send him message that his video is not accurate at all. If someone see that he will get completely wrong picture.
I mean his fan was so loud that I even to put ear directly on PSU grill I don't hear as his video.
On this model 1200 P2 fan is very silent, I'm not sure is it same with 1000 P2 or 1600 P2 but I can say for 1200 P2.
Even in most silent water cooling case with radiator fans on 1200RPM people will not hear normal mode of 1200 P2.
Probably is difference fan PSU work 80%, but no reason to buy PSU with tight space between power consumption and PSU limit.

Yeah, I fired mine up with the tester beforehand and didn't notice it being loud or anything. It's a very slight sound (it can't be heard when the video cards have spun up), but it's noticeable when the PC is idling. I'm leaning toward trying out another one, unless someone can confirm that the erratic power draw is the way it's supposed to work.

I noted this on my last build with the Same UPS Unit that you have. Great Unit By The Way
I have a 1300G2 and the X79 FTW Motherboard and was seeing the same wattage bouncing up and down.
I have 5 other 1300G2 in rigs and none of them show this wattage drop. Two tested on the Same UPS Unit to make sure the UPS was OK.
I pulled out the X79 FTW and will replace it with the X79 Dark Motherboard to see if it acts the same way. Waiting for UPS to drop it of today!
It will have all the same Parts, CPU, Ram, Video Card so it should be a good test to see if the Power Supply is the cause and not the Motherboard.
If it does then I will request and RAM on the 1300G2 and to note it is a Brand New Power Supply. The 1300G3 has no eco mode.
Also this wattage bouncing up and down only happens with the computer in an idle state, if it is in heavy use I do not see the wattage bouncing.
And to note as well with the computer turned off the UPS will show 0 Wattage and Bounce to 59 or 65 watts and then drop back to 0 and then repeat.
 
But on yours if you turn off or set eco mode OFF do you still see the wattage bouncing up and down? I read the above Edited Post never mind.
 

Well now I'm a little concerned since you're seeing this behavior, too (and the fact that not all of your 1300's exhibit it is a little more concerning). My machine will normally idle between 130w and 145w with the monitor running, so I really don't like the fact that it's jumping up to over 200w when it's just puttering along. Now I just need to figure out the quickest and easiest way to get a replacement... I've yet to register it, but I'm also inside the return window with Newegg...
 
Haven't noticed the wattage fluctuating with the PC turned off yet, but I only just fired it up yesterday. It's been off since early this morning, and was displaying 0w when I checked it just before leaving for work.
 
Thanks for replying! Glad to know I'm not crazy, even if I am being a bit paranoid.

I will post an update as soon as I Install the new Motherboard.
In my case I am hoping that the cause in from the X79 FTW Motherboard and Not the Power Supply.

It looks like you're running an R4F in one of your systems, same as me. Does that one have one of the 1300's installed, or is it still running the NEX1500 that's listed in the Mods Rigs write-up? Mine definitely didn't exhibit this same behavior with the AX1200, so I'm inclined to think mine has to be the power supply, which was the main bit of hardware I changed out over the weekend... unless, of course, the 1200 P2 functions in a way that is fundamentally different from all my previous power supplies.

Nope, this is that rig now X79GTX690Cruncher and it is now using the 1300G2 with no issues at all.
I am pulling down the CPU Water Loop to change it around to get better water flow.
Same MB ASUS Rampage IV Formula System 2 AX1200 PSU
ASUS Rampage IV Formula System 4 has been split into 3 different rigs the current one active is the X79GTX690Cruncher
And that one was taken over now by my X99 Classified Rig X99GTX980Cruncher This Best has One 1300 G2 and One 1600 G2 installed.
The 1600 G2 Powers the 4 GPUs and the PCIe Extra Power on the MB and the 1300 G2 Powers the MB and all the items connected like water pumps hard drive fans and so on.
ATM it is Folding HFM on the GPUs and Crunching on the CPU over on BOINC SRBase.

But if I'm reading it right, you do have an R4F paired with a 1300 G2 that isn't fluctuating all the time like the system you're switching motherboards in, right? In other words, you don't have a 1300 G2 that's acting up when connected to a Rampage IV Formula... unless I'm just totally confused now. Which is likely. 

I've just decided to bite the bullet and ordered my own replacement 1200 P2 from Amazon (my original came from Newegg, so I figured the second one would at least come from a different lot/batch if the first one is defective). I'll decide what to do about returning one of them after the dust has settled since I can avoid restocking fees with either one.

BTW does anyone from EVGA ever troll these particular forums? It'd be awesome to get an official answer one way or the other before I go tearing my PC down again. I called support last night and asked about it, but the tech either didn't understand what I was trying to tell him, or he just didn't know. Nice guy, but not terribly helpful.

Testing shows the same power spikes as before so I will open a support ticket on my 1300 G2.
For all I know this might be normal on newer 1300 G2 Power Supplies.
 
I took my PSU out of my X99 Rig and it does the same as the other 1300 G2 but I can only see this on our Model of the UPS.
On my X79 Dark on the Same UPS it does not have the same issue as the other two 1300 G2 PSU.
So I have Two 1300 G2 that have is strange issue and one that does not.
My other test shows that on my APC UPS they do not show the bouncing of power.
I will still open a Support Ticket to ask this same question to them.
 
It is most likely our CyberPower CP1500PFCLCD UPS Units and both mine show the bouncing of power with the PSU on and the computer off as well as with the Computer On in an idle or not using state and we see this bouncing of power.
This is my Full Model of my UPS CyberPower PR1500LCD Smart App Sinewave UPS 1500VA 1050W SNMP/HTTP Mini-Tower
Jan 2015 two each and one in Feb so mine are new units.
 
Also my APC 1500 Pro UPS are NOT Sinewave UPS Units.

No, my older 1300 G2 is working normal my 3 New ones are having this strange bouncing of power and only on the CP1500PFCLCD UPS.
None of them do this on the APC UPS Units.
I have tested all 5 of my 1300 G2 and the 3 last ones I got have this strange issue.
But I do not think it is really and issue anymore. We do have 10 years and I do not even think I will have my current rigs after 5 Years.
 
To let you know also I tested the PSU with only the Power Cable with the Test Plug on it.
So you need not install your new PSU just plug in the 24-Pin Cable into the Power Supply and then plug in the Test Plug that comes with your Power Supply and with the Power Button Off plug the Power Cable the same cable you now use on your computer.
Then Turn on the Power Supply and see if you still have the Bouncing Wattage.

Mine are the CP1500PFCLCD (1500VA/900w)... so it's a slightly different unit. It's an "adaptive sinewave" UPS, but I've never had any problems with it keeping an active PFC power supply going during a blackout (or brownout). I have four of them altogether, but only use the one for my PC and monitor... the rest power my home theater and network equipment. The PC unit is the oldest, but it's only about three years old. The newest one is from January of this year.

I have an older APC SmartUPS unit that is pure sinewave, too; it doesn't have an LCD display, though-- just a series of dots to indicate the battery charge and load. I'll try out both power supplies on the other UPS units, though it will probably be later this week.

I also bought a cheap Kill-A-Watt meter to see if it gives the same reading as the UPS. Maybe between the two of us and all these battery backups we can figure out what the heck is going on.

Thanks again.

I would like to know what EVGA say for your PSU, if you send them.
Maybe is everything OK with PSU.
It was very little complains on P2 series because all reviews say best about them, and new SuperNOVA line.
EVGA will soon probably to launch and 1000/1200 T2 - Titanium. 1KW Titanium will be probably most wanted PSU.
 
Why you post this topic at all.
Now worm eat me inside because we have same PSU. 
 
 

I don't know anything about that worm ya got there.  
 
Seriously, though... I'm planning to check what it's actually pulling from the socket later this week. I obviously thought it was some weird behavior with the PSU when I started the thread, but since bcavnaugh posted some of his findings yesterday, I'm not so sure anymore. It could be this particular UPS unit. I'll be swapping out some parts later this week/next week, so I'll be sure to keep the thread updated with what I find.
 
Thanks!

I hope your UPS make problem not 1200 P2.

We'll find out soon enough. Honestly, I wouldn't be awfully surprised if it is the UPS (not that it's actually defective... just that there is some weird incompatibility with the newer SuperNOVA power supplies).
 

bcavnaugh
I have a Kill-A-Watt meter on the way as well.

 
Something just occurred to me... has your UPS actually kept one of those two power supplies with the bouncing wattage running during a power outage? That would be quite the nasty little surprise if it suddenly reared its ugly little head later on.  I'll be sure to check for that, too, while I've got everything torn apart.

I will test that now for you.

Test One Yes It Holds while on Battery in the Bios. Test Two Yes It Holds while on Battery in the OS.
I am not going to worry about now, I think we are fine. BTW did you pull the Power Plug from your UPS?

Sorry for just now getting back on this... it's been a rough couple of weeks, and and I've been operating on far too little sleep for several days now. It finally caught up with me last night. 
 
The new PSU and Kill-A-Watt did arrive yesterday, though, and I managed to get a couple things done before passing out last evening...
 
The first thing that I noticed is that the unit from Amazon is obviously newer, so it's definitely from a different production run than the first one; the outside of the packaging was a little different, the S/N appears to be a higher number (assuming that they go in sequence from lower to higher), and the tester plug was a little different than the one that came with the original unit (the newer one has a cap on the top of it, whereas the original one was open and had the wire loop from the pins sticking out). I was kind of surprised by this, since I just assumed that Newegg would always have newer stock on something like this, but anyway...
 
I hooked up the new power supply (with the 24-pin and tester plug installed) to the Kill-A-Watt, and plugged it straight into the wall socket. The readout fluctuated between 6.6w (lowest that I observed) and 12.7w (the highest), with no load attached to it. It would occasionally dip low, or spike, but it mostly stayed in the 9w range. I imagine the fluctuation was due to the fact that I didn't have it plugged into a surge protector (or UPS) to regulate the voltage.
 
That's all that I've got for now, though. My rig is located on the bottom shelf of a cramped desk in the living room and is an absolute bear to wrangle into and/or out of position. I also have to clear off a working space in the kitchen for tearing it down again. It will likely be tomorrow evening-- or even Saturday-- before I'm able to devote the time to getting started again. Once I've got the PC pulled out, I'll hook up the new PSU to the UPS and see what the readout shows. I'll also see what the Kill-A-Watt shows for the original unit before I pull it out of the build, since everything is still connected to it.
 
P.S. Thanks for trying out the battery on the UPS. That's one less thing I'll need to do now.

I would not look at the serial number but the lot number.
I am going with what I have and not creating a support ticket.
Also because EVGA did not see any need to post to here we should be ok with or power supplies.
