5 out of 5 eggsstable 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 Haswell Ready

Pros: I've used a similar Seasonic PSU in another build for many years, and it has held up well with overclocking. This one isn't being used in an overclocked system. It is quiet/silent and hopefully will be as reliable as the other one.

Cons: Unfortunately, I had to purchase this PSU to replace another brand PSU that failed. So I paid more than I should have were it on sale at the time. But that's not the PSU's fault.

Other Thoughts: I guess one issue is with the SATA power cable plugs in general. Sometimes the orientation of the plugs is the opposite of what is needed and you end up not being able to use all of the plugs on the cable due to the increased distance between the plugs when the plugs have to be inverted. Again, this is a general issue with all PSU SATA power cables. I wish PSU manufacturers would try to figure out a solution to this.

5 out of 5 eggs

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 Haswell Ready

Pros: Fully modular.
All black cables.
Great efficiency.

Cons: None.

Other Thoughts: Seasonic makes the best PSU's on the market today hands down. They also make many of the other brands PSU's. My mentality, why drive a Toyota when you can drive a Lexus? Why buy Corsair when you can buy Seasonic?

3 out of 5 eggsGood PS - bad promotion

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 Haswell Ready

Pros: Great Power Supply - modular, allows you to use just what you need to keep your case clean and flowing air for cooling.

Cons: Knocked 2 eggs off due to BAD PROMO of $15 rebate that I'm still waiting for 6 months later. Followed ALL instructions for submission, "supposedly" rebate was issued - didn't get it, had to call multiple times for re-issue. They said its "supposed" to be delivered by 1/20/15 - Guess what? No rebate check and the Customer Service agent said there is nothing she can do about it. Tell me this - How hard is it to issue a rebate check, put proper sending address and postage and drop in the mail?
Extremely disappointed here, only because I would have used that rebate check to purchase more items from Newegg.
'nuff said!

Manufacturer Response:

Hi Chris, I am sorry to read about the promo issue not properly handled. Please note, this is an issue with NewEgg and not Sea Sonic and I kindly ask that you contact NewEgg. This review site is for Seasonic products. If you have any questions, please contact me at newegg@seasonicus.com Thank you.

Pros: High efficiency.
Above average build quality.
Cables are long and sleeved nicely.
Nice presentation in the package.
Quiet.

Cons: First one was DOA, need better QA before these leave the warehouse.

Other Thoughts: First one was DOA but this one works perfectly. When this goes on sale its hard to beat.

1 out of 5 eggsLOUD HIGH PITCH BUZZING SOUND

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 Haswell Ready

Pros: It works

Cons: Makes an annoying buzzing sound.

Other Thoughts: I spent top dollar trying to get a no noise system and here i am stuck with a loud psu, it works , it powers everything, the fans aren't making the noise, it's the electrical components making this coil whine. I'm not sure what to do i had such high hopes reading all these good reviews on seasonic's x-series power supply.

Manufacturer Response:

Hi Mohammed, Thank you and sorry for the inconvenience. The noise can be indirectly caused by the MB or VGA and I recommend that you first please enable all Energy Saving Modes (ErP) in the BIOS and then see if this resolves your issue. As well, it can be the VGA's dynamic load causing this issue. Please visit www.seasonicusa.com if you wish to do a RMA and let them test the unit for you. Or you can write to me at newegg@seasonicus.com and we will try to sort this out for you. Thank You.

5 out of 5 eggsGood PSU

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 Haswell Ready

Pros: Good quality build.. Virtually silent..

Cons: None so far. Owned few Corsairs before but decided to go with Seasonic. Got it for $99 from Newegg. Thinking I should've went with the Platinum version for $40 more but oh well

Other Thoughts: I bought it new... Not sure why mine was not shrink wrapped. I remember buying a few Corsairs and could've sworn they were all wrapped in original boxes.. Shouldn't have my box been shrink wrapped? Minor wear-tear on the sides of the box. It works and has a good warranty from Seasonic, so I'm not going to complain but I am a little concerned that's all.

5 out of 5 eggsGreat, quiet PSU

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 Haswell Ready

Pros: 650w of 80+ Gold certified power
Can be used in regular or hybrid fan mode
Modular
Lots of cables

Cons: A bit hard to plug in the cables to the PSU itself

Other Thoughts: I had a Corsair PSU that I used for 5+ years, it performed well but I was upgrading and changing cases and I didn't want the PSU to fail and be out a computer for awhile. Also it wasn't modular so there was a lot of ugly cables everywhere. I paid about $105 but it was worth it and I'm happy with the purchase, I run it in hybrid mode and I don't think I've ever heard the fans.

5 out of 5 eggsVery good and well priced

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 Haswell Ready

Pros: Modular, Hybrid/Normal switch is cool for different settings, all black cables, and the packaging was so nice that I felt a little spoiled getting just nice packaging

Cons: For the first 3 days there was some super annoying squealing coming from the PSU, especially when I used the wheel on my mouse (I so wish I knew what caused this), but after that it went away, which is what I expected. I figured it would just need a break in period and my hunch was right!

Other Thoughts: Aside from the annoying sounds (quiet yet audible enough to be frustrating), this is a great PSU. I would have been a bit worried if the sounds were persistent but it doesn't happen anymore and just sits there acting like it should. I'm not worried about it dying on me

5 out of 5 eggsGood so far

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 Haswell Ready

Pros: Wasn't DOA. Removed 5 year old Corsair TX650 with what seemed like was 10yds of cabling, cleaned out the dust, installed new unit, plugged everything in and it's working fine. Of course it's quiet in hybrid mode. No humming, buzzing or other problems so far.

Cons: None yet.

Other Thoughts: This is the KM3 model as reviewed by JonnyGuru. His only real mark down was the price @ $139. If you can get it for $89 or less, you can't go wrong. I know things fail, but like most electronics, if it works when you plug it in, it'll probably stay working. I doubt I could ever go back to a non modular model.
