2 out of 5 eggsBad RMA Service

This review is from: SeaSonic SS-750KM3 750W ATX12V V2.3/EPS 12V V2.91 SLI Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: It worked fine when I first got it. Nice modular PSU with lots of good cables and all the fixin's.

Cons: 3 days of ownership and whenever I played any high resource game, my computer would crash because of unstable voltages of the PSU. I switched out the PSU for one in my old computer and figured out %100 that the PSU was the issue. I thought, hey, no worries, I can just RMA it. I sent the RMA in and hadn't gotten a response for 3 days so I sent an email. Took 2 days to respond and then they asked me for some clarification number I was never given. There is also nowhere on the site to input your RMA number to see the status on it.

IN A NUTSHELL: Their RMA service is 1/5

Other Thoughts: Buy this PSU and hope it works.

Manufacturer Response:

Hi Kendrick, I am sorry for the difficulties you have had for RMA servicing. We are working to improve the RMA processing. Please note, in USA, the RMA is done through www.seasonicusa.com RMA section. There you will be issued a number and instructions as soon as all your information is entered. Thank you.

1 out of 5 eggsAnother defective SeaSonic unit

This review is from: SeaSonic SS-750KM3 750W ATX12V V2.3/EPS 12V V2.91 SLI Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: well rated, excellent selection of cables, beautiful packaging.
Small unit, fits even tight cases

Cons: Unit didn't work, just like the other 3 SeaSonic units I have gotten in the past two months (though those were from other vendors), reliability is a SERIOUS issue.

Other Thoughts: I tested the units using PSU testers, known good computers, and re tested the PSU after, these new X series PSUs have really let me down. The issues have lead me to completely exclude the brand from any future builds.

Manufacturer Response:

Jeffrey, I am sorry for your situation with our products but it seems, maybe, perhaps, your test methodology is at issue here if you have had 3 other units and none of them worked. Suffice to say, to be so unfortunately unlucky, well, from our perspective, a bit difficult to understand. Perhaps you may want to check your PSU tester to see if that is working ok. If you have any questions or concerns, please contact me at newegg@seasonicus.com Thank You.

4 out of 5 eggsSo far so good...

This review is from: SeaSonic SS-750KM3 750W ATX12V V2.3/EPS 12V V2.91 SLI Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: It's working. Noise isn't high. Wasn't DOA.

Cons: Price tag was very high. I hope I am paying for a product that will last me as long as the guarantee says it will.

Other Thoughts: I bought a new power supply because I suspected my previous power supply crashed my mother board which I had to pay an arm and a leg to replace. I got this power supply after hearing many reviews that Seasonic is one of the top companies for this product. Will keep posted over time. Let us see if they are as advertised
