I've been reading reviews that the G3 is fairly noisy compared to other PSUs. Anyone care to share their experience?

    I just received it yesterday and I'm trying it out.  Yes, I saw the same review on Tom's.
     
    I had it on ECO mode.  The fan suddenly kicked in and it was VERY notable.  I do have a pretty quiet case, so it was a very sudden increase in fan noise.  I have the 850W version.  I think this was more temperature driven than load, as my build doesn't have too much wattage need, nor was I doing anything that was straining the system.
     
    Because I've only had it a day, I'll keep trying it out.  Maybe it'll do better with ECO mode off, so that there's a continuous cooling effect?

    I think I read that - that someone thought it'd be, or it was, quieter if left off ECO.

    Thanks for sharing.

    Well, this is rather depressing news. I was all set on purchasing a G3 1000W, but it looks like I’ll need to rethink that decision in light of this fan noise issue.
    (I thought the only downside to the G3 line was the caps in the cables, which I’d resigned myself to deal with.)

    Testing it further the past couple of days, this 'catchup' fan noise is definitely temperature driven rather than load.  Using a watt-meter, my rig has only hit 350W when running graphics-driven applications (i.e. games).  It kicked in when the PSU was pulling 150W, which is the usual draw at idle.  I have not tested full load though.
     
    My case temps are not that great though so perhaps with better case cooling it would not activate so quickly.
     
    The max fan noise is unfortunately very notable even coming out of the Fractal Design R5, a case specific for noise dampening.
     
    On the other hand, by turning off ECO, I have to say it is whisper quiet and it is very difficult to hear it at all.

    If ECO mode is off, the fan runs all the time, just slow enough so that it is hard to hear?
    Won't the fan still be "VERY notable" when the card is pushed and becomes warm?

    Excellent point, yes it probably would.

    I don't have a system currently that can get to such a load so I can't say for certain, but it is something to think about.

    The excellent Tom's hardware review never tested with eco off so it's hard to say for sure.

    Hi,
     
    Welcome to the forums.  If ECO is on then the fan will not spin unless needed and if it is needed then it will turn on to cool the unit.  If you are not maxing out this unit then the fan will rarely turn on.  Also one of the reviews for the 550W G3 has noted that the noise was around 27 dBA when the fan was activated.  https://www.pcper.com/reviews/Cases-and-Cooling/EVGA-SuperNOVA-550W-G3-Power-Supply-Review/Efficiency-Differential-Tempera
     
    I can also confirm that if you do not want this type of behavior then you should consider turning ECO mode off and the fan will run all the time to avoid it turning on at a higher RPM.  
     
    Please take note that the above is not the same for the 1000W and higher models of the G3 as they are a bigger unit and will have less use of the fan in most cases, depending on the configuration and ambient temps of the room as well.

    Hi,
    I am interested in the 1000W version of the G3. However, if it's going to be noisy I'll need to broaden my search.
    So I guess my question would be is the fan in the 1000W the same noisy level as the 750W or 850W when it's running?
    Thanks...

    I have no experience with the G3's however so I can't comment on them specifically, but I have had similar experience with their other units. I love EVGA but in my experience as well, their power supplies can be noisy.  I had very similar loud noise issues with the fan cranking up to high RPMs with ECO mode to the point where it became very annoying so I switched to the Corsair PSU I have in my sig. The fan literally never comes on for me, except maybe sometimes in intensive gaming but at that point I'm wearing headphones and my GPU fan becomes the louder fan anyway.  I feel that EVGA needs to apply a more gentle fan curve, or some sort of re-design as there are competitors with lower fan noise for the same wattage size of PSUs.

    Tom's Hardware just came out with their 1000W review, so you can judge for yourself.
     
    Unfortunately the take home message, using their testing methodology, is that it's not quiet. =(  The final page of the review hypothesizes on reasons why.

    I have the 850W G3, and I have to say I'm pretty disappointed.  Eco Mode is useless - as stated by others, it's silent for 10 minutes or so, then the fan kicks in at a VERY high speed/noise level.   And this is idling in Windows.
     
    Eco mode off solves that, but the fan speed in non-eco mode is fast enough to be quite audible.  It is easily the loudest thing in my case (given that my GPU is water cooled).

    Own a 1000W G2 and find the fan is incredibly noisy on that model. Didn't realize how loud it is till I rebuilt my computer for silence. Before I had all the fans on blast. Half tempted to RMA to see if maybe it's the fan going bad. Sounds like the fan is grinding on itself. It has been running non-stop for the most part, and on its side in a 900D since July 2013 though. So it's possible it's gone bad.

    Edit: Also interesting how the manual says there is an ECO switch but there is in fact not one. Might just go ahead and pick up a 1000W T2 if my sleeved EVGA cables are compatible from the 1000W G2. Or maybe just sell it because I can't trust the fans to be quiet enough from an EVGA PSU. Going to see what Seasonic and Coolmaster have.

    Edit 2: Seasonic Prime 1000W Titanium and Cablemod cables on the way.

    This is somewhat disheartening to hear since I was planning on buying a 750W G3 for my next build coming up. I may end up getting it anyway just to test it out myself, but I am definitely a little worried.

    The first and only place I looked was Seasonic at their Prime Titanium series. They are claiming 20-25 dB during load. So with a fluid dynamic bearing, should be little to no friction noise unlike sleeve and ball bearing fans.

    I wonder why EVGA didn't address this issue as it looks like the older generation had excessive noise issues as well (from what @loveha posted above).

    I will. Never uploaded to YouTube before, but if I figure it out there will be a couple videos comparing the noise. Also downloaded a decent dB meter on my phone (LG V20) and caibrated it in a silent bedroom. It's more or less for the sound difference though. Not an actual reading. I looked into buying a sound meter but just about all between $30-$150 only go down to 30dB and Seasonic is claiming 20-25dB. When I do my testing I will be doing this with Eco mode off on the Seasonic so the fan is always running. My current PSU has Eco mode supposedly but I don't think it does because in a freezing cold room with no load the fan still spins. Will also be doing it after about an hour of gaming so the PSU has had time to get warmed up properly. Delivery expected Tuesday so expect an update Wednesday.

    I honestly can't wait. I'm pulling for the Seasonic honestly. Hopefully it makes EVGA work harder on acoustics because that is the direction the average person leans towards now days. We want as quiet a computer as possible.

    Well, they (EVGA) do say in their G3 1000W Overview literature (on Newegg for instance) "EVGA ECO mode means the power supply is completely silent during low to medium loads. This is one quiet power supply!"

    Hi everyone,
    I've got a G3 850w in my Phanteks Eclipse P400S TG with Asus Z270e / i7 7700k / NZXT Kraken X52 (2 NZXT 120mm fans @ 500 rpm intake) / 1 BeQuiet SilentWings 2 120mm 1000 rpm exhaust AND... a GeForce 1080 Founders Edition (1100 rpm @ idle, 2200 rpm @ load).
    My temps @ idle are 30°C i7 / 33°C 1080. At load in WoW Legion 40°C / 83°C.
    Well... the G3 is THE most audible component in my case... i've got ECO on... well this is a hairdryer sound. My GTX is silent compare to the G3.
    Going to check a Seasonic Prime Titanium 750w. Sad panda here :(

    Got some time to try and make a video. Sound does not record well on my phone. So I just used a dB meter I downloaded on my phone. I turned my fans up to what I normally have them at which is about 850RPM. Which is just enough to feel the air being pushed or pulled out of the radiators.
    The noise at the front taking measurements is about 30dB (+-1dB).
    The noise at the rear down at the PSU is 40dB (+-1dB). It also sounds like a grinding ball bearing, or motor noise at least.
     
    EVGA needs to have a look at the motor design they are using. Ball bearing fans is a form of friction, friction creates noise.
    Now I could be wrong, but when I listen to my Corsair ML fans I hear nothing but wind going through the radiators and filters.
    ML and FDB there is no friction. One is levitating and the other is gliding on oil.
     
    Now I am still awaiting my Seasonic PSU, but I expect it to be as quiet if not quieter than the rest of my fans at around the 30dB my phone is saying.

    Ok, cause I was gonna say that B&H is closed due to the Passover holiday and won't reopen again until Wed., April 12 (tomorrow as I write this).

    Can I ask you which Seasonic did you choose ?


    Seasonic Prime 1000W Titanium. I chose that because at half load of 500W which my system pulls roughly when gaming, is when the PSU is most efficient of 94%. Give or take a bit as that is what my UPS says with my monitor hooked up to the battery as well.
    I just got it hooked up in place of my EVGA 1000W G2. I can not hear it and the fan is on right now. My case and radiator fans are at 825RPM. The G2 was 10dB louder than my fans....
    I have some testing to do over the next couple days such as game with the fan on and see if it gets louder, and game with the fan off and see if it kicks on like a fighter jet. I am already very pleased with what I am hearing though.
    Now at the bottom of of this page it says...
    All features may not apply to PRIME Platinum, PRIME Gold Series and PRIME 1000 W Titanium.
    and I am not sure which features those are. I guess I should ask them directly. I know if you look it up on a mobile browser it is missing a couple certificates from outside testing facilities.
    One from ETA, something about 91% to 94% efficiency at any load.
    Other from Lambda with it saying 20dB to 25 dB during operation.
    So if you are really worried about those two things for some reason I would get one of the lower wattage Titaniums because the 1000W does not have them.

    EDIT: Been gaming (FFXIV) for the past few hours so the system has been under load for quite some time, and the fan has not changed speed that I can tell. I turned the fan off to see if it stayed spinning and it shut right off. This is with the game still running. So yea, Seasonic Prime Titanium PSU big thumbs up from me.

    @loveha - thanks for posting your experience so far with the Seasonic Prime 1000W Titanium PSU. It sounds (no pun intended) like a winner.

    So, was there a noticeable difference in the sound level of your system when you did this?
     
    Also, I note that the Seasonic is approximately $100 more than the EVGA G3 1000W at Newegg right now. I would hope you're getting more for your money if you know what I mean.

    Very noticeable sound difference between the two.
    More for my money? Over time, as a Titanium PSU is more efficient than Gold.
    Not to mention it has a 12 Year warranty compared to EVGA's 10 Year.
