1 out of 5 eggsNice packaging, poor product

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: Nice packaging (now I know why it was expensive), and good amount of cables.

Cons: High pitch noise on day 1 in a new build. I thought it was not that annoying at this time.
After almost 2 months, IT IS annoying.

5 out of 5 eggslasted 3 years so far, still alive and kicking

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: bought it in October 2011, still works just fine. keeps quiet and cool, amazing packaging

Cons: only con might really just be me being an idiot somehow, I recently moved my entire build into a new case, whenever I plugged the hdd in my pc wouldn't turn on at all. luckily the power supply comes with some extra cables so I switched them out and everything works fine

3 out of 5 eggsSolid but failed after 2 years.

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: Ran quiet for 2 years.
Nice simple pro design and packaging.
Modular and nice cabling.

Cons: Failed, could no longer power my GPU. It appears One of the PCI-E modular cables had melted into the PSU.

4 out of 5 eggsGood so far, but...

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: Modular, with a lot of connectors. Quiet. Efficient.

Cons: I wish the cables were a little longer and with a little more space between the drive connectors:

1. The PSU is mounted in the bottom of my large tower case, and the server motherboard has the 24-pin and 8-pin connectors along the top edge, just too far away for me to bring the 24-pin cable up the back of the MB mounting plate and through the adjacent cutout: I have to use an extender if I don't want to run the cable in front of /on top of the motherboard and perhaps block needed airflow.

2. The Molex and SATA connectors are just too close together to allow one to connect to each of my iStarUSA drive cages: I can use only alternate connectors.

2 out of 5 eggsCoil Whine

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: Great packaging, quiet fans, compact modular design, stable power.

Cons: Has had a distinct and noticeable intermittent coil whine since day one. I even went through the trouble of RMA with newegg to see if I got a bad unit but got the same results with the replacement.

Manufacturer Response:

Hi Joseph, Sorry for the inconvenience. Please note the coil whine can be an issue of the MB and or the VGA in combination with the PSU. It is best is you can activate all energy saving modes in the BIOS, this might help. Please write to me at newegg@seasoniceu.com and we can try to help resolve the issue for you. But it might not be a PSU issue.

5 out of 5 eggsFlawless

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: 0db, dead silent, high performance, great flex to the modular cables (usually modular cables are stiff), velvet bag

Cons: the velvet bag

Other Thoughts: Who bags a psu in a velvet bag? i guess the answer is seasonic. Frankly this is both the most hilariously awesome corny and lame add-on to a power supply I've ever seen. No clue what to do with it now that i have one. but it was sorta wild to pull the psu out of it in the first place. definitely a picture i emailed around a bit. Anyway now that i've wasted your time let me lay this out there

this is the best psu i've ever owned.

2 out of 5 eggsWell, it wasn't DOA at least

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 works

Cons: - When it powers on for the first 2 minutes it makes a screeching noise that eventually fades away. It does this in normal and hybrid mode. and is completely unacceptable.
- The connectors don't click into place. they just sort of push in and don't seem fully secure. Is it plugged in or not? I dunno, let's turn it on and see...

Other Thoughts: Gonna RMA and go with a Corsair.

Manufacturer Response:

Hi Brodie, I am sorry to read of your issue and I hope the RMA process works out well for you. If you have any questions or concerns, please let me know at newegg@seasonicus.com Thank You

2 out of 5 eggsCoil Whine (Buzzing 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: Nice packaging, decent modular design. Power delivered is stable.

Cons: Coil whine noise is produced during random activities (mostly gaming), the buzzing sound is almost unbearable. For the price of this PSU you'd expect more.

Other Thoughts: The manufacturer likes to pass blame to your other components but this is unlikely the root cause for noise problems.

It was a hassle, but I finally got around to swapping out this PSU for my older Enermax PSU and as expected, NO NOISE PROBLEMS now. I will avoid buying Seasonic in the future.

Manufacturer Response:

Hi Travis, I am sorry to read of your issue. Please e-mail to me at newegg@seasonicus.com with your system configuration and the type of VGA used and we will try to sort this out for you. Thank you.

3 out of 5 eggsWonderful, until...

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: Fantastic modular design, sooooo quiet (because of the efficiency that leads to the fan not having to run -- and the Nippon Seiki fan is so quiet, you don't even hear that when it DOES have to run); packaging, quality manufacture... just great.

Cons: Unfortunately, mine failed.

Other Thoughts: Now, it failed after four years. For an average PSU, acceptable, I guess. But for this unit (and I paid a full $140, I wanted it so bad), not so good. The 5 year warranty is bailing me out here, but I'm still stuck with an unusable $2800 power PC for several weeks and am forced to type this out on a tablet. I've never had a PSU fail on me before -- and, in my very early days, actually trusted one that cost $30, which I now very much know was a piece of cr#p (not purchased at Newegg, btw). I know anything built by humans can't be perfect, and Seasonic will -- I trust, given the warranty -- take care of this, but it is very disappointing to be without my "big PC" and my new CPU/MB/RAID array, all purchased through Newegg. I'm going to be without for several weeks, and I didn't expect this to happen with one of the best reviewed (both professionally and peer reviewed here on Newegg) PSUs in the world.

Manufacturer Response:

Hi Dean,
I am sorry about the failure of the power supply but if you contact Sea Sonic USA, the RMA process is quite fast, it is very possible within 1 week you will be up and running, if not less. If you have any questions or comments, please contact me at newegg@seasonicus.com Thank You.
