1 out of 5 eggsQuality Control!

This review is from: SeaSonic X-1050 ( SS-1050XM2 ) 1050W ATX12V / EPS12V SLI Certified CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: The PSU looks like a quality engineered component. It wasn't until I plugged it in that things went downhill...

Cons: I installed the SeaSonic PSU, hit the power button, the lights flickered on for a split second and... nothing. It took me awhile to figure out the problem was the power cord socket on the back. If I pushed sideways on the plug, the PC sprang to life. Once I let go, it died. I unplugged, reinserted and even tried a different power cord, but got the same result. This seems like a simple case of absent quality control.

Manufacturer Response:

Hi Ryan, Thank you for your review. Please note, all units are fully tested before it leaves the factory and as well, this applies to the AC Socket. Can it be possible that you did not properly insert the AC Cord into the Socket? If you are able to push it sideways, then possibly the AC Cord did not get seated properly. But again, it can be internal. The best thing I recommend is that you would send this unit to our USA office for RMA support. If you have questions or concerns, please contact me at: newegg@seasonicus.com Thank You.

5 out of 5 eggsExcellent Power Supply

This review is from: SeaSonic X-1050 ( SS-1050XM2 ) 1050W ATX12V / EPS12V SLI Certified CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: -Stable
-Good build Quality (Especially internals)
-Efficient [80+ Gold]
-Quiet most of the time; if not silent.
-Fully Modular
-Well priced (~$160)

Cons: -Color Scheme is questionable [subjective]
-Somewhat larger than other power supplies
-Stiff cables (Expected with Seasonic)

Other Thoughts: When installing the Seasonic X-1050 Gold, I first noticed the size of the power supply. Although I expected a slightly larger than usual PSU, it actually covered a slight bit of cable-management grommet.

Being a fully-modular unit, cabling was an easy task, with the exception of some cables being a tad bit shorter than I would like. Nevertheless, I have my own sleeved cables which worked fine. Also, the cables are rather stiff, almost to the point of being annoying. I actually cut myself while managing some of the cables.

Anyways, the power supply internally is what I have come to expect from Seasonic, the soldering done very cleanly and without any issues. The layout is well organized with a healthy amount of heat sinks and a single 120mm fan. The AC power connector is somewhat stiff, and takes quite a bit of force, which is actually an advantage as it takes a bit of force to pull out. The only negative thing I could find is that the AC connector moves ever so slightly in place when force is applied. This is actually not an issue, as it is merely because the "can" holding the connector has a miniscule gap between it and the assembly, thus a bit of wiggle room. However, there is no real risk or issue of anything going wrong due to this. It is not even noticeable unless one is really looking closely.

As the power supply is rated 80+ Gold, one can expect an efficiency of somewhere around 87~90%. If the load is continuously greater than 950 watts, it would be somewhat risky to exceed this amount for an extended period of time. However, occasionally bringing the load to >1000 watts should be fine. Running dual R9 290Xs at 1200/1400mhz, the max load alone from the GPUs can be as much as 700 watts, however, I have never noticed any stability issues due to the power supply. Under maximum load, the fan may spin up and become audible, but the noise has never been intolerable. In comparison, even my WC pump and radiator fans are usually louder.

Priced as ~$160, I think the Seasonic X-1050 is a great power supply for the price, and is actually re branded by other brands (hint XFX).

Manufacturer Response:

Thank you Eugene for your support and the very nice review!

2 out of 5 eggsUpdate - Fails to power on at ~2 year mark.

This review is from: SeaSonic X-1050 ( SS-1050XM2 ) 1050W ATX12V / EPS12V SLI Certified CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Modular, Silent, Looks good?
In a bottom case location and in hybrid mode, the fan almost never kicks on.
Easy to clean, if you need too as the fan grill is removable.
Lot of cables, SLI and Sata cables are nice length.

Cons: The CPU and 24pin are very short. If you have a large case with a bottom mount PSU and connectors at the top of the MoBo this may be a bad choice.
Died - frequently fails to power on at the 2 year mark, powers on maybe 1 in 10 attempts. This is the third Seasonic X-1050 I have seen with this problem, mine and a friend had two bad ones in a row with the same problem after returning the PSU twice to Newegg. I suspect their QA/QC could use some work.

Other Thoughts: RMA'd. Expect Seasonic to fix it, but their RMA process is painful. We will see if they actually fix it.
Tested the PSU and it is Faulting on Ground, 5.5v and 3v. Other PSUs work in the PC, but this PSU fails in other PCS.
Gave it 2 eggs for the update as Seasonic, so far, has honored the warranty and it did last almost 2 years.

Manufacturer Response:

Hi Daniel, my apologies for the inconvenience caused with the RMA. I am not sure what you mean by the RMA process being painful and wonder if our service center will actually fix it. We honor the full period of the warranty and this you need not be worried, so long as the unit was used for its intended purposes and was not opened. If you have any questions or concerns, please contact me at newegg@seasonicus.com thank you.

5 out of 5 eggsWorth the money!

This review is from: SeaSonic X-1050 ( SS-1050XM2 ) 1050W ATX12V / EPS12V SLI Certified CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Solidly engineered PS that works as advertised. Silent in hybrid mode under normal use at 50% load. Beautiful packaging and nice accessories included.

Cons: I agree with other reviewers that the included cables are difficult to bend near the ends. (tho the cables are of high quality)

Other Thoughts: This is really scenario specific, but I wish there were more (and longer) molex cables included (for use with sata backplanes for example). Including one more of the long 3-plug molex cables would have fit my needs perfectly.

Pros: When working it was a great power supply

Cons: It broke after two years.i shipped back to seasonic and over three weeks later have still received no reply or aknowledgement from them.i called them (seasonisus) and the rma extension takes you to a voicemail with foreign accent and asks for a email.i have received far better service from most of there competitors.I will never do business with them again,and i advise you dont unless 3 weeks plus without a pc doesnt bother you.

Other Thoughts: Customer service is more important than the product but i guess they dont care.im off to buy a replacement

Manufacturer Response:

HI William, I am very sorry for your RMA experience with our USA office. The person in charge of responding to RMA is currently away from the office for the week, and therefore the delay in response. Please let me know your RMA number and I will track it for you. Please send e-mail to: newegg@seasonicus.com Thank you and I am very sorry for the inconveniene this has caused.

4 out of 5 eggsA good option

This review is from: SeaSonic X-1050 ( SS-1050XM2 ) 1050W ATX12V / EPS12V SLI Certified CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: -pretty nice

-great quality

-works great

-fully modular

-good price compared to other high quality options such as (cooler master v1000, corsair hxi or rm 1000w, and antec true power power supplies)

- great warranty 5 years

- fan is extremely quiet (also includes hybrid mode with the fan)

Cons: - Silver mounting screws

- terrible modular interface with a bunch of big bulky plugs ends which make it really hard to bend the cables

- also really weird labeling, seasonic wants you to have the fan up you can put it down but the labels on modular interface is upside down and the power supply label will be facing on the otherside so you can't see it.

Manufacturer Response:

Thank you for your review and input. I will foward this to our product manager. As for cables too stiff when mounting, you can use a hair dryer on medium setting to warm up the cables a bit before installation. As for the labeling and fan on which way to mount, please note, some cases have the PSU on the top and others on the bottom, therefore we have to find a midway solution for both. Thank you for your support.

1 out of 5 eggsStarted failing after 12 months

This review is from: SeaSonic X-1050 ( SS-1050XM2 ) 1050W ATX12V / EPS12V SLI Certified CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Pretty geek purse
Modular
Black

Cons: Started failing after 12 months--if I powered down, I could not restart unless I pull the power cord for about 10 minutes.

After 18 months, PC would suddenly shut down

Other Thoughts: This was an expensive PS that replaced a Corsair HX that failed after six months. Have replaced with this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16817438013

Fingers crossed. PS like hard drives seen to fail far more than previously was the case

Manufacturer Response:

Hi John, I am very sorry for the inconvenience. Please kindly contact Seasonic USA RMA service for support. If you have any furhter questions or concerns, please contact us at newegg@seasonicus.com Thank You.

This review is from: SeaSonic X-1050 ( SS-1050XM2 ) 1050W ATX12V / EPS12V SLI Certified CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Great psu. Fully modular. Well packaged 80+gold rating. Long cables (but could use a couple more inches on the 8pin CPU connection.) I was able to run all cables behind the mobo tray on a nzxt source 210 white case. (has lack of space behind the tray compared to some cases I've used.) comes with a two pocket bag for all the modular cables along with Velcro straps (6), and zip ties.

Cons: I haven't found any so far.

Other Thoughts: Wish it was cheaper
