5 out of 5 eggsHigh Quality

This review is from: SeaSonic S12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 80 PLUS BRONZE Certified Active PFC Power Supply

Pros: -Price
-80 PLUS Bronze
-Quiet
-Reliability
-Build quality

Cons: -none

Other Thoughts: I've had this PSU for like 4 years and it still gets the job done. No complaints. I'll likely upgrade to a more powerful unit at some point and opt for a modular model as well, but when I do, I know it'll be a SeaSonic.

5 out of 5 eggsSatisfied

This review is from: SeaSonic S12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 80 PLUS BRONZE Certified Active PFC Power Supply

Pros: Wired very easy.
Fit well in case.
Very quite.
More than enough power for expansion of system.

Cons: None at this time

Other Thoughts: My current PSU was knocked out by a power spike. The PSU and USB Hub were the only issues after knocking out the surge protector. I spent about 30 days researching the PSU that I was going to purchase. I felt this is one of the better PSU's, so I purchased and installed the unit. My one big requirement (besides it working) was the ability to grow my system without having to replace the PSU. I almost sent it back DOA, but I read a review that this needed to be installed for it to operate (I guess complete the circuit). I installed it - it works! I could not be any happier.

This review is from: SeaSonic S12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 80 PLUS BRONZE Certified Active PFC Power Supply

Pros: Still running:
Installed around 2012-11 (November 2012),
Still running as of 2015-05 (May 2015).

SeaSonic S12II 620 Bronze

Cons: None in almost 3 years and counting.
If there are, I will certainly update this review.

Other Thoughts: They were still using colored cables when I purchased it,
and now appear to use black wiring on all models now.
Cosmetic only, no actual functional meaning.

This review is from: SeaSonic S12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 80 PLUS BRONZE Certified Active PFC Power Supply

Pros: -Well priced
-It powers my computer

Cons: -Extremely Loud

Other Thoughts: After spending money changing my gpu and cpu coolers, (I assumed those were making all the noise.) Turns out it was my Seasonic PSU. This power supply is so loud that I stopped playing intense games like BF4, Crysis 3 etc. and only play older games now.

If you plan on doing intense gaming and noise is a factor I suggest you save your time and money.

Manufacturer Response:

Hi Kenneth, I am very sorry about your experience with our product. The S12II-620 is with fan control and if you push the until to full load, then the fan will go to max rotation to cool the PSU. As well, you alos will need good ventilation in your system to remove the warm air. If you wish, please visit www.seasonicusa.com and start the RMA process so the unit can be tested for compliance. If you have any questions, please write to: newegg@seasonicus.com Thank you.

5 out of 5 eggsI really like it so far

This review is from: SeaSonic S12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 80 PLUS BRONZE Certified Active PFC Power Supply

Pros: The main pro is that it is dead silent. I can't hear it over my case fans and they are silent fans also. I have it bottom mounted and it was easy to install.

Cons: None so far

Other Thoughts: It is not modular. However, I am a lazy builder and lose parts I don't need sometimes. Then, when I mod a build, I go looking for things and can't find them. I can't do that with this PSU. Everything is there. You just need a case that allows you to hide the cables and it is fine.

3 out of 5 eggsDoes the job.

This review is from: SeaSonic S12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 80 PLUS BRONZE Certified Active PFC Power Supply

Pros: Does the job.
Not loud.
Reliable

Cons: NON-MODULAR

Other Thoughts: If you care about airflow and the clutter inside your case, especially if you have a window. The rats nest of unused cable in the bottom of your case I personally hate. I wish I had gotten a modular power supply.

Manufacturer Response:

Hi Seth, I am sorry you are disappointed by the power supply being non-mondular but it is, afterall, marketed and sold as a non-modular PSU. If you wish to have a modular PSU, please consider our M12II, X, P or FL series power supplies. Thank you.

2 out of 5 eggsOne year and done.

This review is from: SeaSonic S12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 80 PLUS BRONZE Certified Active PFC Power Supply

Pros: Good solid power supply that was reliable.

Cons: Only lasted for a year and now it clicks and clacks likes like a train going downhill.

Other Thoughts: Really disappointed with Seasonic given their reputation, and frustrated with the rma process. Its almost not worth the roll of the dice on the rma when I could buy a new psu from a different company.

Manufacturer Response:

Hi Andrew, I am sorry about your experience with our power supply. The noise can be a wire touching the fan blade. You mentioned you were frustrated with the RMA process? Did you do the RMA direct with Sea Sonic USA? The proecss is fairly simple and straight forward. Please visit www.seasonicusa.com and start the RMA procedure. If you have any difficulties, please contact us at: newegg@seasonicus.com Thank you.
