Can anyone confirm if the so-called "coil whine" has been fixed with this PSU? I've read where a lot of people had this problem. Thanks for you input!

Yes it has been fixed at least in the one I bought. No whine or any noise for that matter, sometimes I wonder if the fan even works. This is truly the best power supply I have ever owned and it is extremely efficient. I noticed a 32Watt drop in power usage after in installing it. Migrated from a PC-Power & Cooling PS measured by Kill-A-Watt.

I've had mine for a about 6 months without any significant noise. Coil whine is non-existent and I am very happy with the product performance.

It's a junk low of the low tier psu, spend the extra money and get a sea sonic or superflower made unit, my cx750 had major coil whine. I now happily own a silent evga g2 850w psu made by superflower.

I have not had that occur. I wish I could tell you more about what is causing that noise. It might have done so, but I had mine installed by a professional and I was not there for the testing. I have not had a power failure so it has not had to kick in either, so I haven't heard it in operation.

Hi sorry to hear about the issue. If you have tried everything with no luck, would suggest swapping it out for another. 1 of 3 I purchased we ended up returning. Now, we got ours at a local store so I didn't have to hassle with repackaging/shipping. My sister bought one and had issues as well. I commented on the table top version of this fan that unfortunately the manufacturer is not very consistent, or that QA is lacking. Despite the little issue i had, I am very very satisfied with my purchases. Good luck and I hope you get to enjoy your fan soon!

the power supply fan is really loud after installing I've found, I think its a big drain on the PSU

As long as your fan is clean, there really shouldn't be much noise under different load mods. I haven't heard that the fan is an issue.

not much you can do about the noise besides replace this with a better one such as Corsair. But you are looking at more like $60-$100, BUT A GOOD psu IS THE BASE FOR ANY GOOD COMPUTER.

1) did you make sure the heat sink was applied properly? what kind of temps are you getting @ bios when you reboot.2) power supply: how old? what kind of wattage?3) Have you tried doing any other intensive tasks like gaming or running a test app like SuperPi? Does it shut down then?

Well I havent seen their reviews so I don't know the conditions the had the failures from . but I can say this I own one of these cards and have been very happy with the performance and reliability of the card so far. My guess is that ppl who are having issues result from majority of 3 causes. 1 Low quality power supply or not enough wattage. 2 bad cooling air flow. Or 3 no understanding of how to properly overclock the card. The included software makes it very easy to make changes but this card already comes overclocked so if you push with out good power or cooling there will be problems like with any card.

Yes, i have a 500+ power supply inside this puppy as we speak. It was extremely tricky and seemed impossible for me to get my power supply in so i like ziptied it and that caused it to bluescreen, you need to make sure you get it in correctly and screw it in properly, though i didnt know how until i had a repair guy check it out.

I own the evga 850 To be honest to me it is not loud at all! i don't here it. but i got other fans that are running in the background. also it has a no fan switch on the back that only kicks in when it is needed. But i will never buy a nother corsair psu the other one i got it was a cs 750m that died on me (the fan stop spinning) look up the reviews on it. so i am staying away from corsair.

I purchased an XBR4 46" the last week of December. It had a fan noise or hum right out of the box. I have it on a table, so there are no enclosure issues here. I also have it plugged into its own outlet and not a power strip with other devices. The noise is very irritating especially since I know other people that own the XBR sets and they are dead silent. I returned to Amazon. It was painless. My new set was just delivered this past week and it is every bit a noisy as my first one. I love the picture but hate the noise. I also don't think the noise is normal or acceptable. I will contact Amazon this week to see what they are willing to do. I purchased an XBR4 46" the last week of December.

'course! I've not had that issue with this case buuuuuuuuuuuuut there's a few things we can do! Firstly, make sure all the power cables to the fans coming from the case are connected to MOLEX/4pin power connectors (or the relevant ones for the fan you are connecting) and if it's still not receiving power and spinning up either A) Send the case in for replacement or B) Try a replacement power cable to the fan. Not really much more help beyond that which can be offered I'm afraid!

I have had it since October with no issues at all.I must say that a BIOS update was needs because there were some throttling issues, and I consider unacceptable fiddling with a brand new out of the box new GPU BIOS.But beyond that I haven't had any problems.Probably some production batches were faulty and hence people having issues with it, maybe I was lucky.So far my experience with this card has been great, but that's just me.

Yes...Haswell architecture. I purchased this mid-July from Amazon, and have had zero issues with it, and no coil whine in my unit. Mine is essentially silent, and has run perfectly since day one. Battery life is excellent, and responsiveness with the SSD is fantastic - this does a cold boot in a few seconds, and wakes from sleep almost instantly. Display is the best I've seen, period. Fantastic machine overall.

What I did was open the case and take the guts out. I ported them to a case with a 120mm fan. I had to solder a bit and it was a pain in the butt. The PSU is decent here but it sounds like a jet engine. Mine had TWO 80mm fans. Insane. Now I have one decent, quiet PSU. Another option is to simply unplug one of the fans - unscrew the back and unplug the intake fan (facing the Mobo). You probably want to leave the exhaust fan intact.
