Pros: Quiet. Perfect for my needs.

Cons: Cables too short for mid-tower. Intervals between connectors too short. Had to re-arrange drives to get all of them connected.

4 out of 5 eggsGreat 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: I have owned this for around 9 months now

Very quite
Very easy to install
Can power the following

fx8350
Sapphire tri-x R9 290 4GB
8GB corsair ram
2x WD HDD
1x Samsung SSD
6x Fans
Fan controller

I do not dare play a game on it though, as I had a 7870XT and a fx4300 before. Apparently full load with CPU and GPU will kill the PSU but that was using a 650w RM Corsair PSU which is pretty similar.

I also brought a new x-series 850w and it DOA

Cons: MB sleeve is not as flexible as I wanted it to be, but then again this is my first full modular PSU.

Other Thoughts: I wouldn't bother buying the 650w, in New Zealand the 750w is only an extra $20 and you get two more years warranty

Manufacturer Response:

Thank you for the nice review. Please note, for the DC cables, you can use a hair dryer and warm it up a bit and this will help with the flexibility. Thank you.

5 out of 5 eggsseasonic used to mean no frills

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, extreme silence! very attractive, cool features
solid construction

Cons: the motherboard cable is sleeved but all the other cables are exposed plastic. Be careful of sharp edges in your case!

Other Thoughts: Seasonic used to mean simple but solid. Dependable and usually ugly. No more, this is one elegant PSU that comes in a velvet bag.

5 out of 5 eggsBest power supply I have ever owned

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: Rock Solid. Silent. Very Efficient.

Cons: Packaging is a little to elaborate for my taste. Personally I would prefer them to pack it in a much cheaper box and pass on the savings to the customer.

Other Thoughts: My experience with this power supply has been great. I have been running my computer pretty much 24/7 for the past 3 years with this power supply without so much as a hiccup. And I really love not hearing a fan spin.

4 out of 5 eggsreplaced this psu with thermaltake toughpower

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
easy to plug in
all labeled

Cons: Not a con but i wish the cords was a little longer for better cable management capability in a full size tower. Otherwise it's perfect for a mid size tower.

Other Thoughts: Would buy again. I replaced this psu for thermaltake toughpower cuz that died. So far this seasonic modular psu seems pretty cool and good design.

1 out of 5 eggsMissing Accessories and Poor Customer Service

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: The power supply hasn't broken.

Cons: My power supply did not come with all of the cables necessary for its use. I contacted Seasonic to ask for a replacement cable, but apparently they are unwilling to replace cables 10 days after the invoice date of your order. In other words, you have only a few days after receiving your PSU to build your system, regardless of potential technical issues or RMAs of other components that might delay your build.

Other Thoughts: Because of Seasonic's error I was unable to fully use my product without paying an additional cost to their distributor.

Seasonic boasts a 7 year warranty but this apparently excludes the accessories that are needed for the main unit to function.

Manufacturer Response:

Hi Adam, I apologize for your experience with our product. We have procedure set in place for such situation and we will make an internal review. Normally speaking, all cartons are checked for cabling before it leaves the factory and the cartons are sealed. Can you please tell me which cables were missing? Please contact me at newegg@seasonicus.com Thank You.
