5 out of 5 eggsSolid PSU

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: Very, quiet, stable, and well-built. Zero issues.

Cons: None.

Other Thoughts: I build and buy a lot of computers and components, and I am not very brand loyal for most things. In general, any PSU will work fine most of the time for average users. At home, though, I only buy Seasonic. Period. I like to have all of the computers use the same modular cables, and with one kid who is a hardcore PC gamer and one that does a ton of scientific modeling, I just can't deal with down time and instability. I have never had a Seasonic PSU fail, and the small price premium is well worth it for me.

1 out of 5 eggsDead after 3 months

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: See below

Cons: Dead as a doornail 3 months after purchase. Now I have to pay to send a heavy power supply back to seasonic for replacement. I liked this power supply and I thought with a name like SeaSonic I wouldn't have any issues. Having to tear down your entire rig to remove your power supply is no fun. Hopefully it is replaced in a timely fashion or you will see me update this review with another rant.

Manufacturer Response:

Hi Jason, I am sorry for the inconvenience. We try our best to ensure the best quality but being analog devices, things can fail but we hope our service center has resovled your issue properly. As well, being a modular power supply, you only have to remove the PSU itself by detaching the cables and I hope this reduces some of the work involved. If you have any questions, please contact us at: newegg@seasonicus.com Thank you.

1 out of 5 eggsDOA, Twice!

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: None, :-(

Cons: The power supply arrived DOA. Everyone has a bad day, so I asked for a replacement. The 2nd power supply arrived DOA. That makes me question their testing procedures. The 3rd power supply came from another manufacturer.

Other Thoughts: Newegg's RMA procedures were outstanding. Two thumbs up.

Manufacturer Response:

Hi Stephen. I am sorry to read of your experience. If your replacement also was not able to boot your system, perhpas it is not the PSU but either the way you installed or there is possibly something wrong in your system? If you have any questions or concerns please contact: newegg@seasonicus.com Thank you.

1 out of 5 eggsFailure in less than 60 Days

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: Great cable system and a very pretty packaging for the unit.

Cons: Lost the power rail for the Motherboard in approximately 50 days. Currently going through the RMA process on the unit. While unit is out for work I switched back to a 5 year old Thermaltake unit that was solid in my previous computer.

Other Thoughts: Cost to send it back isn't exactly fun given the weight of the unit.

Manufacturer Response:

Hi Ethan,
Sorry for the failure of the unit. We try our best to ensure top quality and we are sorry when this happens. Please visit www.seasonicusa.com and start the RMA process. Thank you. Please write to: newegg@seasonicus.com if you have any questions.

1 out of 5 eggsWarranty EXCLUSIONS! Beware!

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: Seasonic brandname. Generally thought of as a solid well engineered PSU. Run several of them, was all I would buy for my new PC builds.

Cons: Beware of thier 5 and 7 year warranty. While it will cover the PSU itself, cables are not covered. Buying new cables for your specific device is NOT cheap! Might as well buy a whole brand new one for the cost of a new set of cables. NEVER again will I purchase this garbage, off to EVGA, Antec, or Thermaltake. Maybe they will treat the people who actually buy their products better than this once good company.

Manufacturer Response:

Hi Eugene,
I am sorry to read of your review. Can you please let me know what went wrong with the cables? Sorry, we don't cover user damage but if it was something else such as manufacturering defect, then the cables are covered. Please write to me at newegg@seasonicus.com Thank you.

5 out of 5 eggsGood customer support

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: After 3 years my SS-750KM failed. I was working on my computer and it just turned itself off. I grabbed a spare supply, if your computer is really important then always have a spare, and I was back in business. I went to the Seasonic web site and got an RMA. I sent it to them and they immediately sent me a new one.
I wish all companies were so responsive.

Cons: It's heavy so it costs more to ship it back, if you consider that a negative.

Other Thoughts: Well made power supply that is efficient and quiet. 7 year warranty is fantastic and they support it.

5 out of 5 eggsSuper Quiet

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: Extremely Quiet
750W 80 Plus Gold
Fits my mid tower case perfectly
Amazing high end packaging!

Cons: Not free?

Other Thoughts: This thing is super nice looking and sturdy as heck. It came in really really nice packaging with bags for the PSU, cables, screw, and cable ties. Everything feels pretty high quality. This PSU actually cut my power usage at peaks by 20-40 watts under full cpu and gpu loads. For the extra 40-50 bucks more than my old PSU, this seems well worth it, as long as it last a long time. My old one did last about 5 years.

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.
