2 out of 5 eggsRandom shutdown

This review is from: SeaSonic X Series X650 Gold ((SS-650KM Active PFC F3)) 650W ATX12V V2.3/EPS 12V V2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Packaging was good. Came with a bag for the cables as well. Pretty quiet when it worked.

Cons: The unit would randomly shut down my computer. The power would just turn off instantly at times when the computer was at idle or if a youtube video was playing or gaming. It can shut down at any time. Sometimes it wouldn't shut down for a week and other times I could experience this 3 times a day. It is absolutely random and I've RMA'd the power supply once already. The replacement did not fix it. I've also RMA'd my motherboard tried different GPU's thinking those were potential issues. In the end, I used a spare PSU and that one worked with no problem for the whole month that I had it.

Other Thoughts: There's something wrong with this unit and it seems other people are reporting the same issue as well. Maybe it is with a particular configuration.

Manufacturer Response:

Hi Chris,

Random shut down can be attributed to a variety of issues and even possibly software (virus) related. The replacements we provide are all tested to Intel and Seasonic specifications and to have 2 untis exhibit the same behavior can potentially mean the problem's root cause is not necessarily the power supply. If you have further comments or concerns in this regard, please contact me at newegg@seasonicus.com Thank You Very Much.

2 out of 5 eggsHorrible reliability

This review is from: SeaSonic X Series X650 Gold ((SS-650KM Active PFC F3)) 650W ATX12V V2.3/EPS 12V V2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: It's fairly quiet. Packaging looks good.

Cons: Randomly shuts down my computer. RMA'd it once and it still does the same thing. Tried a different PSU and that one was fine. I'm not even running anything too power intensive. A 4770K at stock and a R9 290 at stock.

Other Thoughts: I see others reporting the same thing. There hasn't been a fix that I am aware. Seasonic RMA process was fairly quick though.

Manufacturer Response:

Hi Chris, I see this is a repeat post. Again, if you have any concerns or comments, please write to me at: newegg@seasonicus.com Thank you

5 out of 5 eggsSo far so good, no coil whine or noise

This review is from: SeaSonic X Series X650 Gold ((SS-650KM Active PFC F3)) 650W ATX12V V2.3/EPS 12V V2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: 1. Great packaging / organization
2. Modular
3. No noise

Cons: 1. You might have possible coil whine due to hardware compability issues. It's not an issue of the PSU, getting a replacement will yield the same problem

Other Thoughts: i5 3570k
MSI p67-g45 b3
sapphire 7850

I was torn between getting a fanless 500w power supply or this x-650. The only thing keeping me from buying this power supply was the complaints of 'coil whine'. Luckily for me, there is no coil whine audible farther than an inch. If I put my ear right next to it, yes there's a slight noise but that's normal and definitely not audible from a distance at all. So far, 10/10. It is pretty much silent. We'll see how long it lasts before it goes kaboom! :)

1 out of 5 eggsBad news

This review is from: SeaSonic X Series X650 Gold ((SS-650KM Active PFC F3)) 650W ATX12V V2.3/EPS 12V V2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Works fine in Seasonic fasion for six months. The packaging is a thing of beauty. Most cables from older Seasonic PSUs work fine with the newer supplies.

Cons: The power supply completely failed after six months. Not a good showing!
I confirmed the failure by replacing the PSU with a Seasonic 460W X series fanless.

Manufacturer Response:

Hi Willliam, I am sorry for the inconvenience of the RMA. Please contact our USA office to start the RMA processing. If you have any questions or issues please contact me anytime at newegg@seasonicus.com Thank you.

This review is from: SeaSonic X Series X650 Gold ((SS-650KM Active PFC F3)) 650W ATX12V V2.3/EPS 12V V2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: The modular design keeps the case clean, and it's quiet.

Cons: It failed twice over the course of 2.5 years. It's now in the trash can.

Manufacturer Response:

Hi Mike, Sorry for any inconvenience caused by the RMA. Can you please let us know how the unit failed twice. Normally when the power supply fails, it will not boot up again. Please contact our USA office for RMA and I am sure they will gladly take care of it for you. If you have any quesitons or issues, please contact me at newegg@seasonicus.com Thank you.

5 out of 5 eggs2011 and Beyond

This review is from: SeaSonic X Series X650 Gold ((SS-650KM Active PFC F3)) 650W ATX12V V2.3/EPS 12V V2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Reliable

From a 2500k in 2011 and its going in my new Haswell build next week. Overly thrilled with its reliability and power output.

Cons: See other thoughts

Other Thoughts: Note: During the time this was the norm but todays standards have gone in the direction of separate sleeving. I would like to see more PSU distributors incorporate that feature.

1 out of 5 eggsCapacitors Popped

This review is from: SeaSonic X Series X650 Gold ((SS-650KM Active PFC F3)) 650W ATX12V V2.3/EPS 12V V2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: It worked well while it lasted.

Cons: One day outside of the return window and the capacitors pop with smoke emerging from the back of the unit after attempting to wake the computer from sleep. I have ordered a different supply to see if any of the other components survived. With the price of this unit, this is a fairly unacceptable way for it to fail so soon. After going through the reviews for the x650, it would seem a few others have experienced this problem as well.

Other Thoughts: Instead of all of this fancy packaging, can I have sleeved cables instead?

Manufacturer Response:

Hi Kaleb, I am sorry for the failure of your power supply. Please contact seasonicusa.com to start the RMA process. We try our best to make the best possible power supply but failures do happen though we make every effort to minimize it. Please note, all Seasonic power supplies are equipped with the necessary protection features to ensure the safe operation of your system. As for cabling, some prefer flat cabling and some prefer the braided cables and we had to make a choice and opted for the flat cabling for the ease of system build. If you have issues or concerns, please contact me at newegg@seasonicus.com Thank You.

5 out of 5 eggsGood so far

This review is from: SeaSonic X Series X650 Gold ((SS-650KM Active PFC F3)) 650W ATX12V V2.3/EPS 12V V2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Completely modular and so quiet running with the side off I don't hear it running
at all with the fans on a load,switch it to hybrid mode and the fans don't even
come on.Very pleased with this buy and the rebate just makes it better.Newegg got it to my house in record time as usual. I'm also glad to see the cables for a
floppy drive because, well I still have a few lol

Cons: None

Other Thoughts: This is the first power supply I have bought since 2008 and it replaced a 950wt
CoolMax that has ran my gaming rig that is still got a original Foxconn Destroyer mobo, 8 gigs of Gskill DDR2 1066, 1 Evga GTX+ 7900 and a dual core
unlocked AMD 555 @ 3.9 with a Raptor 10,000 rpm all original. The only reason I've had to buy a ps is someone thought they would vandalize it and they evan
broke the on and off button on the AOC monitor.But after putting in the new ps
everything is stroking like it has since 2008 and it's a nice feeling, oh yeah✌

1 out of 5 eggsFailed Seasonic Power Supply

This review is from: SeaSonic X Series X650 Gold ((SS-650KM Active PFC F3)) 650W ATX12V V2.3/EPS 12V V2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: well packaged and quiet until it prematurely failed

Cons: Seasonic X650 Gold failed after 3 years. The power supply would shut down immediately after power up. I sent the unit in for warranty repair. The returned unit made so much noise it is unusable.

Other Thoughts: Seasonic does not have customer friendly support. The support email address on the Seasonic web site is incorrect. You must request an RMA and mail the unit in (at your expense) to receive warranty support. Since I've sent the unit in once before, sending it back a second time is a gamble. The Seasonic warranty has minimal value.

Manufacturer Response:

Hi Clair,
Sorry for the inconvenience of the RMA process & the failure of the power supply. Please note, we do try to produce products of the highest quality and when failures occur, we try our best to rectify the issue.
As for the RMA procedure, it is our standard procedure that the freight is paid by the sender. I am sorry about the replacement unit being noisy. All replacement units are well tested before sending so please let me know your RMA number and we will investigate this matter. And as for the contact e-mail address, please let me know to which address did you send the informtion as I have checked, all addresses are correct. On Seasonic USA site, there is a direct RMA link to use for RMA processing. Please e-mail the information to: newegg@seasonicus.com Thank You.
