Load ~650 watts from PSU. I can see up to 12.41V with voltmeter. At idle 12.3V. Don't you think that this is too much for this PSU? Should i worry?
You're being far too negative, but I can't tell you what to think. All I can tell you is, you're likely dealing with a defective unit and they ship a huge quantity of these things out to retailers and they do the best they can to avoid shipping out defective PSUs, but it does happen. There is absolutely no way to guarantee that it won't happen. You're expecting perfection out of things that are made by human beings. No human is capable of producing perfection 100% of the time. It can't be done. Flaws happen. Even things made by machines and computers can have flaws because those machines and computers were made by people. No matter what, you cannot remove the human element.Originally Posted by booya
Yes, but I'm 100% sure the company knows that it has such devices and gives the go-ahead for shipping. Now I have doubts about the other characteristics (ripple and efficiency). And buyers have to spend time to return this junk
But in the reviews everything is just fine. And if not, the company prefers to contact the publisher and understand, why the results were not as good as they would like. So the only thing that works well in Seasonic, is the marketing department.

My multimeter is OK, my power line - I have UPS (APC SUA2200I) and even when working on batteries (pure sine wave) the voltage is the same.Originally Posted by TwoCables
Also, consider that it could be a problem caused by the power coming from the wall outlet.
Many people complaining about it. This is too many for Seasonic-level PSU. Esp. Titanium series. It's not cheap Enhance or else. 12V overvoltage is not uncommon for all Seasonic models.Originally Posted by TwoCables
Regardless, I want you to see that you're negatively judging all of SeaSonic over this one solitary PSU.
By the way, you specified an article at jonnyguru.com. Please pay attention to the inscription:Originally Posted by TwoCables
I'd say something is wrong with the meter.

Excuse me, but I can buy a simple ATX PSU for much less money. And for 15 years I met only one power supply unit, which had such overvoltage at 12V. In addition, your company claims only two percent, not 5%. And you call it Ultra Stable Voltage Regulation. Same about Micro Tolerance Load Regulation (0.5%). I do not see it on my device. Nothing out of this.Originally Posted by Sea Sonic Rep
We are sorry that this "junk" PSU is still within ATX specifications but not as good as expected.
I will repeat that the company is aware that it sells power supplies with such undocumented parameters (Who cares? Only a small part of the users will insert the multimeter probes into the peripheral connectors to measure the voltage. And if such users are unhappy - then we can always find a compromise, because it's cheaper than setting a strict quality control). And your words mean this. Please correct me if I'm wrong.Originally Posted by Sea Sonic Rep
Also, all PSU's shipped are tested and if they are not as good as expected, they are simply not shipped from factory and will have a rework to meet the specifications announced.
And when I have to send a faulty device to you, what do I use?Originally Posted by Sea Sonic Rep
Also, we are confident in our products and this is why we offer a 12 years warranty.
I live in Russia (Moscow). If you do not have a time machine that you could give me for a while, then I'm afraid you can't help me. No one will refund my time. I can return this power unit to the store on my own. But thank you for trying to help! As I wrote, the only thing that works well in Seasonic, is the marketing department. And of course engineering department, no doubt about this.Originally Posted by Sea Sonic Rep
This said, may I know where you are living in order to see how we can assist you if needed?
Thank you for this post as I own a Seasonic Titanium PSU. This reinforces my positive view of Seasonic as a first rate company and I will continue to buy and recommend your products.Originally Posted by Sea Sonic Rep

For me it is obvious, that this is almost the best example they managed to find. This is not a regular PSU, which is for sale. The man (Jonny) acted honestly and wrote about it. Other publications may be silent.

Let me think about it. I hope the store will not mind.Originally Posted by Sea Sonic Rep
Is it possible to at least let me know the serial number of your PSU? It will still help us to track it for test. Then, if you still want to do a step to us, kindly email us.
1) Please see above.Originally Posted by Sea Sonic Rep
I'm back to you as I just talked about this issue with our Product Manager and we would like to know few things:
The power supplies that I had and which left behind some impressions:Originally Posted by Nukemaster
Maybe I should not dip into this, but the actual idle to load is still VERY small and no hardware will be harmed by it.
You can buy 100s of ICs and have slight variations in all of them. I am guessing the same happens in the parts that make up a power supply. If it makes you feel any better, most switching regulators are more efficient at high input voltages
First I get this answer:Originally Posted by blaze2210
booya, show me a single large company on the planet that has never had any sort of issue whatsoever with their product(s). Things happen, which is exactly why the companies that stand by their products offer good warranties. The 12 years mentioned here is far longer than any warranty I currently have in place for any of my components. When issues with parts arise, what's important is how the company responds to it. In your case, Seasonic has stepped up and given you a solution on a silver platter.
Hello Booya,Originally Posted by booya
Hello!
I buy these things only in those places where there is money back.
And I got another power supply of the same model. 12V voltage regulation now within 2% (at least at ~70% load, this is all I can do). Still not as good as in the reviews! But OK.
As you can see, the cables and the instructions are packed differently
Let me think about it. I hope the store will not mind.
1) Please see above.
2) Intel i7-3930K C2 (OC'ed)
ASUS Rampage IV Extreme
Corsair CMD16GX3M4A2400C9
GTX 980Ti (OС'ed)
Creative SB X-Fi Titanium HD
4xSSD
Aquacomputer Aquaero 5 PRO + some fans
The pump is connected to an external PSU
3) 3DMark (Sky Diver) + Prime95 (Small FFT)
4) Peripheral connector
The load is monitored through the UPS (SUA2200I)
The power supplies that I had and which left behind some impressions:
2x Hiper Type R 480W (HPU-4M480)
Hiper HPU-4M730-SK
Cooler Master RS-500-AMBA-D3
Cooler Master RS-700-AMBA-D3
3x Corsair AX850 (Seasonic!)
Corsair AX1200
Corsair AX1200i
Enermax EES350AWT
Enermax EES400AWT
Enermax Platimax 1500
Chieftec GPS-500C
Thermaltake W0428RE
Thermaltake W0426RE
Thermaltake TP-1500M
None of them had such an 12V overvoltage as my first SSR-850TD. It should be noted, that some PSU from the list had problems of a different kind and even more serious ones. Seasonic this is not cheap brand and you expect more from it than from Cooler Master, Thermaltake and any other brand, whose power supply units are built on simpler platforms. Except powerful CWT and Flextronics, which are made by order of Corsair. Such PSU I can put in one line with Seasonic.
The increased voltage is due to the improperly operating feedback of the power supply. Somewhere so. I do not know the details.
First I get this answer:
We are sorry that this "junk" PSU is still within ATX specifications but not as good as expected.
I still do not understand if the company believes this is a defect or not?
But I still believe that Seasonic is trying to give to the reviewers the best copies of their products (it's normal, but...).
