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 Hasw

Pros: I own four SeaSonic power supplies. They are of the highest quality. SeaSonic designs and builds all their own power supplies, most manufacturers do not, even most of the big names. Quiet. Their fan speed control is the best.


You could buy cheaper but not for this quality.

5 out of 5 eggsGreat product, and despite mechanical failure, Seasonic has the best support I've ever dealt with. (Re-review)

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 Hasw

Pros: +PSU worked fantastically for three years of near constant load. It was easy to install. It's near silent and looks pretty.

+As will be mentioned in my cons, my unit suffered a mechanical failure after about three years of use. It was a bizarre failure and very damaging (took out multiple parts) but those sort of things happen when it comes to computers. What matters is how a company deals with it. This product has a seven-year warranty, and while their phone support/automated system isn't great, directly emailing their RMA department (the email is listed on same page as RMA info, very easy to find) was a fantastic experience. The support was prompt, knowledgeable, and they were willing to give me a packing slip because of the damage to the rest of the system (no guarantee there). Compared to other companies I expected to fight with them for weeks over this. instead? There's only one company that does it better.

+For their great support alone, all my future builds will use Seasonic products.

Cons: -It failed after three years and took out a lot of my computer's components requiring expensive replacements that I couldn't really afford at the time. That said, this is something that can happen with any PSU.

Other Thoughts: -Maybe I sound like a broken record, but Seasonic support is the reason I can so easily recommend this product (Whoever works the 'Kevin' name is doing a great job). It takes a good product line and a lot of confidence for a company to go so far with their support. I've been building computers a long time and usually it's miserable, this time, it wasn't.

Manufacturer Response:

Hi Alex,

Thanks for your comment. We are glad that our RMA service in US helped you like you desserved it. Thank you for your trust in Seasonic's products.

4 out of 5 eggsGood Power Supply. Bad manual.

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 Hasw

Pros: From the Specs this should be a good power supply, efficient, reliable. A 7 year warranty means they are serious about quality. I have had Seasonic and Enermax power supplies in the past and have never had a failure. Very nicely packaged, quality look and feel. It does seem to loaf along and run cool and quiet, with a stock I7-4790K, and a GTX970. It has the modular cable system, which makes for a clean install. Buy American.

Cons: There is one 8 pin CPU connector and 1 each convertible 6/8 pin video card connector. There are more 6 pin cables marked PCIE. The manual is practically useless, 7 pages in about 17 languages, and reads like a low tech sales brochure. No Specifications, No pinouts, No wiring diagrams. Very cursory connector labeling, no explanations. I did not have a good feeling about the convertible video connector and had to do internet research, but it all worked out OK.

Other Thoughts: 5 Eggs for the Supply, -1 Egg for the manual. Still, I recommend it.

Manufacturer Response:

Hi Michael,

Thank you for your positive comment about our X-650. We do hope our unit will serve you for years. Also thank you about your feedback on our manual, I have forwarded your comment to try to see if we can't improve it.
Thank you.

5 out of 5 eggsAwesome Powersupply

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 Hasw

Pros: I was in the market for a new PS for a new build I'm working on. My needs were for a PS in the 600-650 range, so this one fit the bill.

This is a very nice powersupply! I was extremely impressed with the packaging of this PS, and more so with the PS itself. Appears to be very well made, nice black powder coating, plenty of modular cords for any need. I dont think I'll own a PS that isnt modular any more. I like being able to keep the clutter down and plug in the connectors that I need.

The PS was packaged in a velvet bag, thought I was getting some Crown Royal lol, and came with several zip ties, Velcro ties, and screws. It runs very quiet. I have to get near the case to hear if it is running.

Cons: None so far.

Other Thoughts: I am very impressed with Seasonic PS. I have one, M12 I think, in another build that is still running strong after 7 years! They were my first stop for this build. It was on a good sale at Newegg so I snatched it up. I highly recommend Seasonic and this PS, if you're in the market for a new PS.

5 out of 5 eggsThe Very Best Power Supply

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 Hasw

Pros: The highest quality Power Supply, if you care about protecting the components connected to your PSU, then Seasonic is the only one to buy.
I have several older PC builds using this PSU, and with all the power surges and power outs here, this is the only manufacture that protected all my components.
And all of my Seasonic PSUs are all working perfect, same as the day that I first received them. 2 of them are 10 years old now.
I love the premium packaging that Seasonic uses for all of their Power Supplies.

Cons: None!

Other Thoughts: The cables have very much improved over the years, making a very clean installation these days. Easy to keep the cables out of the cases airflow path.
and enough extra cables to improve hiding the cables from view and the airflow on my 10 year old builds.
I will always trust Seasonic to provide the very best Power Supply in the entire world.

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 Hasw

Pros: Fully Modular, very quiet, all the power most people need, and a good price.

Cons: None-to-date

Other Thoughts: Some of the modular cables could be 2-3 inches longer, especially since my MB is a litter bigger than most.

1 out of 5 eggsPoor Customer Support by Seasonic

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 Hasw

Pros: NewEgg as always shipped the item in good condition.

Cons: Power supply blew out after about 1.5 months of use. I have sent the power supply back to Seasonic for replacement and it was confirmed to be delivered on Sept 29th, however I have not received any update on the status of the RMA. I have emailed their support division as well as called the office and left a message, still no response. This is not a doc on NewEgg but a warning that my experience with Seasonic customer support has been very poor.

Manufacturer Response:

Hi Richard, I am very sorry for the lack of information. Please send to me at newegg@seasonicus.com your RMA number and we will trace what happened. Thank you and again, our apologies for the inconvenience
