5 out of 5 eggsBought in 2012, still running strong in 2016

This review is from: SeaSonic M12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 SLI Ready 80 PLUS BRONZE Certified Full Modular Active PFC Power Supply

Pros: Good price, fair number of cable options, and has lasted 4 years now.

Cons: Other PSU's will have more options for power cables, check to make sure this one has the ones you need.

Other Thoughts: I had my GTX 550ti and my current GTX970 and have had no issues powering those, an SSD, 2 HDD's, some case fans and a dvd drive. I've had it just over four years and have had no issues. I recommend Seasonic in general.

This review is from: SeaSonic M12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 SLI Ready 80 PLUS BRONZE Certified Full Modular Active PFC Power Supply

Pros: Very quiet,

Cons: None

Other Thoughts: Works great, but don't misplace the extra cables. I ended replacing because I lost the cables that I needed for my new GPU.

3 out of 5 eggsFine for nearly three years

This review is from: SeaSonic M12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 SLI Ready 80 PLUS BRONZE Certified Full Modular Active PFC Power Supply

Pros: Gives you power

Cons: Died before three years of use. Assumed it was a faulty model, but other reviews listed the same problems I had (wouldn't start randomly, random resets)

Manufacturer Response:

5 out of 5 eggsRunning solid for over a year now

This review is from: SeaSonic M12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 SLI Ready 80 PLUS BRONZE Certified Full Modular Active PFC Power Supply

Pros: What is there to say, it is a power supply. It has flat cables, for easy routing to maintain airflow.
It is fully modular so you only use the cables you need, keeping the case clean (and again improving air flow).
It provides the power it claims to provide (according to many review sites)
It is a well established and trusted manufacturer.
Great bang for the buck.
They actually READ these reviews and reply to them! Come on, THAT is customer service!

Cons: Hmmm...hard to find a con. I would say the only con is that it was not free - but I want Seasonic to make a profit and stay in business.

Other Thoughts: This is my second Seasonic out of about 5 different brands I have purchased. I will certainly make my next purchase a Seasonic again.

5 out of 5 eggsAnd this one makes three!

This review is from: SeaSonic M12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 SLI Ready 80 PLUS BRONZE Certified Full Modular Active PFC Power Supply

Pros: Very easy install once again, full modular design is nice and convenient, lots more room in my HAF 912 without the extra unused cables. More than enough power for my needs.

Cons: None. Zero. Zilch. Nada.

Other Thoughts: After my good experience with the OEM Seasonics, I expected the same flawless result with the M12II 620 and pretty much got that - no disappointments. Just wished the fan was a little louder, but that's just me. Now my Core i5 system will never run out of juice. Now to figure out where to stick the badge ^^.

Manufacturer Response:

Hi Juan,

Thank you for your nice message and your long story with us. I do hope this one will last long and that your 4th will also be a Seasonic.
Have a nice day.

Pros: Worked without problems for two years. Minimal noise

Cons: Bought Oct 2013 and crapped out December 2015

2 out of 5 eggsDied after 2 years

This review is from: SeaSonic M12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 SLI Ready 80 PLUS BRONZE Certified Full Modular Active PFC Power Supply

Pros: Very quite
5 year Warranty
Love the modular cables

Cons: I had no problems at all with this unit until it died today with no warning, just POOF power gone. That's far too short of a life span for a supposedly "top quality" PSU. Hopefully the RMA process goes smoothly.

Manufacturer Response:

Hi John,

I'm really sorry for the problem you have with our product. It seems that you have started our RMA process. If you have any question, you can email us at: newegg@seasonicus.com
Thank you.
