Special Features

SeaSonic Power Supply

Ultra Tight Voltage Regulation
Improved load voltage regulation keeps the voltage fluctuations on the 12V output within +2% and 0% (no negative tolerance), and on the 3.3V and 5V outputs between +1% and -1%, which (under 80 PLUS load conditions) results in smooth and stable operation.



SeaSonic Power Supply

Seasonic Hybrid Silent Fan Control - S²FC & S³FC *
The industry first, advanced three-phased thermal control balances between silence and cooling. The Hybrid Silent Fan Control provides three operational stages: Fanless, Silent, and Cooling Mode. In addition, there is a switch provided to allow for manual selection between the Seasonic S²FC (fan control without Fanless Mode) and the S³FC (fan control including Fanless Mode).




SeaSonic Power Supply

Benefits:

  • Reduces noise without increasing temperature.
  • Extends fan life by eliminating unnecessary rotation.
  • Optimizes heat dissipation at all times.
  • Fanless Mode provides unsurpassed silent performance.

New Feature: Hysteresis is achieved by a fan control IC, which optimizes how frequently the fan switches on and off. At 25 °C ambient temperature the fan turns on when the load rises above 35% (± 5%) and it turns off when the load drops below 25% (± 5%). Due to this lag in response the fan switches on and off less frequently, which reduces power loss in Fanless and Silent Mode.



SeaSonic Power Supply

Dual Copper Bars
These pure copper bars conduct high current more efficiently to reduce impedance and minimize voltage drop.

3 out of 5 eggsNice Unit with a MAJOR Nuisance

Pros: Stable, quiet, good reviews by power supply reviewers.

Cons: The first unit came dented, the second unit came with a very, very slight sent on the same side on the same side. The power cable between the outlet and power supply unit is too loose and the slightest movement will shut off your system. If you do not get the cable fitted 100% into the power supply unit, it won't power on. (You'll find yourself wiggling the cable to get the right fit/spot so your computer can turn on.)

Other Thoughts: I needed to apply the right amount of electrical tape to allow the cable to fit into the power supply without being loose. If you periodically need to unplug and re-plug your cable (for moving the case or cleaning inside the case) this will be a major nuisance because you will need to periodically change that electrical tape. You will find that you need to keep cutting the tape on the end of the cable (the end that goes into the power supply unit) to find the right thickness so that it can actually fit into the power supply's socket while not being loose.

4 out of 5 eggsPretty good

Pros: Silent fan, and runs 2 980's like a champ. I've never noticed the fan come on in Hybrid mode, even while gaming. Granted, I don't really check out my PSU fan that often.

Cons: Outside of the first one being DOA, none that I can think of.

Other Thoughts: First one was DOA. The RMA process was pretty straight forward, and only took a while because I dragged my feet. It arrived in their facility on a Thursday and I had a new unit shipped out by Friday.

Manufacturer Response:

Hi Josh, Thank you for the review and I apologize for the inconvenience the first unit caused. I am glad the repalcement is working to your expectations and if you have any questions or concerns, please write to us at: newegg@seasonicus.com Thank You.

5 out of 5 eggsGreat PSU

Pros: A power supply is only as good as the company who backs it. I did have the bad experiance of the power supply going out on me. I did return the PSU and recieved a brand new one before I could turn around. In addition the PSU is very quite delivers great levels and other technicians I know where amazed when I told them I got this for 169 dollars on sale. So at the time I got a killer deal and a great company to deal with. I would highly recommend this PSU

Cons: none

Other Thoughts: The only minor gripe I have is the 24 pin cable. Sure it looks great being a super heavy duty sleved cable. I have garden hoses smaller in diameter then this. However that is the issue the cable is acutually to big. If they could make it a flatter cable that is sleved that would be better

5 out of 5 eggsProb the best PSU on the market

Pros: Great performance, Much quieter than my x series 850w gold from Seasonic ( Could be dieing). This things also has better pressure fan or the way it's mounted makes it work better than the 850w.

Cons: None

Other Thoughts: Wish Seasonic could do a Flat 24 pin cable.

5 out of 5 eggsBest Power Supply I've seen

Pros: Incredible detail to workmanship, packaging, included accessory stuff

Cons: None.

Other Thoughts: I run and electronics manufacturing company that produces specialized comms gear.

Bought this for my son for a Christmas present. I'm so impressed, I think I'll be buying Seasonic supplies from now on for everything I build.

5 out of 5 eggsRound 2 after RMA

Pros: Very efficient. Hybrid mode. Packaging, extras and looks. More than enough power for now and allows me to add whatever I feel like to the system. I did get it for a really good price with the mail in rebate.

Cons: Barely fit inside my Define R5 case - width wise. it is a rather long as well PSU and limits some options in the bottom of the case. Fan is a little louder than I would like, but depending on your environment it may not be noticeable.

Other Thoughts: I am writing a new review - see the previous. I contacted Seasonic because I couldn't believe the fan should be on constantly and at that high sound. Turns out it was a problem with the PSU. while I was a little disappointed with their follow up - I didn't know what the error was, but hey they sent it back so it's good. Anyway, got it installed. Works well and hybrid switch does work now. Fan I don't think comes on with my current draw. When I switch to normal mode I can hear it, even in a case designed for sound reduction. I have the fan side down. If this were set on the floor or further away I probably wouldn't notice it, but since I have it on my desk to stay away from pet dander / dust I can hear it. Not a deal breaker, but not sure I have the "one." it's not really fair to call this a con, but it is pretty big and there's no way I can install the Fractal Design water cooler in the bottom as I can't have a PSU longer than 165mm. Anyway, Seasonic did fix in my RMA so I am looking for a 4.5 egg rating since there isn't one I'd go with 5. It's not their fault if I'm picking on it for not being exactly perfect for my set up. I purchased this item for the price, reputation and because it gives me no restrictions in the future and this item still satisfies those.

Manufacturer Response:

Thank you very much for your review and should you have any further issues, please contact us at any time. Sorry for any inconvenience this has caused and thanks again for your patience and understanding.

5 out of 5 eggsSolid performance

Pros: Johnny Guru rated this 9.8 / 10 score in June 2014. He would've given the Value rating a 10 instead of a 9 if the unit was selling for $30-40 under its normal three hundred price tag. Newegg was selling this for the price of the 860 platinum when I was shopping for a beefier unit. No-brainer to select this unit. I've got one of the better PSUs on the planet & 1200 watts of it for nearly half price brand new.

Cons: I have to turn it upside down inside my CM 690 II Advanced which then means I have to plug cables in upside down? There's nothing wrong with this device. I feel like I stole it.

Other Thoughts: I was using 500 watts of my 5 year old Seasonic 520 watt PSU and wanting to upgrade the 6850 GPU to the MSI Lightning R9290x. Now I could get two of those monsters and still have 20% overhead! All of these cables are the perfect length for this mid tower, and I'll move this unit over to a Phanteks Luxe chassis in a month - with no extensions necessary.

2 out of 5 eggsGreat if I can get it to work

Pros: Wonderful for the 170$ i payed for it

Cons: Ever since i hooked it up. Every now and then my computer will shut off and flicker on and off continously untill I unplug it. Assuming its a problem with the PSU. Anyone who can help please contact me ASAP.

Manufacturer Response:

Hi Nicole, This applies to your double post. If your system shuts off and then flickers on and off continuously, then most likely this is a MB issue and not the power supply. It is possible your MB is failing or you may have a short circuit somewhere in the system that is causing the reboot or causing a protection circuit to kick in. Please write to us at newegg@seasonicus.com and please let us know more about your situation. At the same time, you may wish to contact your MB company for possible remedy. Thank you.

2 out of 5 eggsVery good if i can get it to work properly

Pros: Got it for 170$ on sale. For the price this thing is a beast.

Cons: It worked wonderfully for about 2 weeks. Then one day my PC shut down and was flickering off and on every 5 seconds. I unplugged it and made sure everything was connected properly again, and it did it again a little while later. Iv'e checked my temps, "in case of throttling" and never went above 60 when it happened. So my only thought is that it is the PSU. Going to have a friend bring over his PSU to see if it is the problem. I hope its not, don't feel like dealing with RMA.

Other Thoughts: If anyone knows how to fix this please let me know.
