1 out of 5 eggs2 out of 2 seasonics ive bought in the past few months have been defective

This review is from: SeaSonic X-SERIES X-1050 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: One of the easiest ways of wasting $239.99!!!

Cons: This is my second review of a seasonic product and a second faulty product...

This is the second seasonic i purchased within the past few months and so far 2/2 were faulty out of the box (the other being the ss-860xp2). I was unable to test the products within a month for neweggs return policy so i couldn't return through them. I tried filing a rma with the actual company website and they failed to provide me with a return code to write on the box for which they gave me all other instruction as to mail it. Also WORST COMPANY SERVICE EVER. I still have not gotten through to them via email or phone call.

I will never buy a seasonic again because I have effectively thrown away $500. 2 psu's bought in a month, same company, non functioning right out of the box....

Manufacturer Response:

London S., Sorry to read that 2 different model PSUs both failied out of the box for you. How unfortunate to have this happen to a single person, it almost seems... unbelivable.... Please provide the serial numbers to us at newegg@seasonicusa.com and we will provide immediate support. Please also provide the e-mails you have sent to our company so we can trace what has happened. It seems interesting that both units were not used within the NewEgg replacemnt time period and in both instances strange that Sea Sonic USA did not provide any support.... how coincidental... Regardless, we wait for your e-mail over this matter. Thank you.

This review is from: SeaSonic X-SERIES X-1050 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: I prefer the wrapped wires SeaSonic provides over the flat ribbon style cables some of the other companies use. They are more flexible and easier to organize in my opinion.

The cables are also a good length for me. Some power supplies come with cables that are way too long and they take up a lot of room in the case.

This P/S supports 3 separate PCIe connections (8 or 6 pin) . There is a lot of flexibility if you install multiple graphics cards.

The fan is quiet.

Cons: No issues so far.

Other Thoughts: The Power Supply itself it fairly large. I had to modify my case to install it. Every case is different of course but where my old 750 W supply could be pulled out or installed fairly easily, this one would not fit without making some modifications to widen the hole that the P/S had to slip through during the installation. Its not an issue once installed it just be able to maneuver it into place.

5 out of 5 eggsso much power!!!!

This review is from: SeaSonic X-SERIES X-1050 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: I got this psu as an overkill for my pc so i can get upgrades in the future. This psu is pure quality and very dependable. no problems with it on my end and im looking forward to my rebate >:).

Cons: I'm am pretty sure this is due to the tolerances when manufacturing but the power cable for the motherboard was an extremely tight fit for me which scared the living hell out of me using this for my first pc build. I had to use a lot more force than i am comfortable with so watch out.

Other Thoughts: SOOOOO MUCH POWER SOOOOO DEPENDABLE ITS BEAUTIFUL.

5 out of 5 eggsBomb-proof power supply

This review is from: SeaSonic X-SERIES X-1050 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: It's been running 24/7 365 in a BOINC rig with 2 GTX780's and an FX-8350 with everything water cooled, it's been pulling down right around 850 - 900 watts at the wall, the GTX780's are pushing 1228MHz with the TDP at 104% - 106% for either GPU (won't be able to push them much higher without a custom VGA BIOS). These power supply's are well worth the investment and SeaSonic builds PSU's for Corsair and XFX just to name a couple (though they don't do the engineering for their competitors).

Cons: These reviews really have me baffled, they are identical for this PSU and the X1250, both PSU's have the same reviews, word for word, something's not right about that. I really wish Newegg wouldn't let non-purchasers leave reviews, a lot of them are fan-boys and trolls

Other Thoughts: I have an X1250 on the way, I'm going to use it with an FX-9590, 2 GTX780Ti's on an Asus Crosshair V Formula-Z (no bottleneck yet with the PCIe x16 2.0 with present WU's) with 32GB DDR-1866. I'll be using this at GPU-Grid and CPDN too (everything water cooled, of course). It will be interesting to see how well the X1250 holds up pushing all that juice 24/7 365 (yes, I'm fully aware of the electric bill). I just wish SeaSonic made some bigger PSU's, I have 4 rigs running BOINC ATM, 1 with an X750 and the other 2 with X850's. I've never had any issue's with any of my SeaSonic PSU's. Kyle Bennett over at [H]ardOCP I think is one of the toughest, most critical and hardest to please reviewers on the internet, he says it like it is and he gave this PSU high marks (I like JohnnyGURU too, kind of goofy but a through reviewer, also excellent marks.

5 out of 5 eggsI love my PSU

This review is from: SeaSonic X-SERIES X-1050 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: - Lots of room for the future
- 5 years warranty
- Seasonic
- Powers My computer
- Modular (No mess inside my computer from extras cables)

Cons: There isn't anything bad to say about this. Only thing that was difficult about this was plugging in the cords to the psu were tight. But that is not a con. Now they are solid in my computer and will only come out if I want them to.

Other Thoughts: I wanted to get a platinum rated psu. But Gold was still efficient.

5 out of 5 eggsX=10

This review is from: SeaSonic X-SERIES X-1050 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: steady and robust, great cable selections, easy to install and use

Cons: stiff cables

Other Thoughts: This modular PS is top notch in my opinion, the cabling selections offer many options for conventional and non conventional PC set ups. The power ports are clearly labeled and easily accept the cable connections. I didn't dock an egg for the cable stiffness. because this may only be a con for my set up and others may welcome a well wrapped cable system.
