1 out of 5 eggsNo Post & Shuts off

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: cheap (was on sale when i bought it), has good features, modular

Cons: worked great for a few weeks, then the pc shut off, would power on with fans spinning but no post, (no power to cpu?), the it would fully boot for a few minutes then shut off and be dead for a few days thought it was the mobo but no this psu did the same on another system tried different PSU hx750 and both systems ran without fail, so i got a dud power supply, $$ wasted

Other Thoughts: i will stick with high quality, not cheap, brands i know are reliable, ...... it took me far to long to figure out it was this power supply, cause me grief, cash flushed

5 out of 5 eggsIt's a Seasonic...

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: Sturdy construction, fully modular design, rock-solid performance, five-year warranty

Cons: Not free, only 80-plus bronze

Other Thoughts: Solid power supply that occasionally goes on sale for ridiculously low price.
Silent operation, unimpeachable power delivery... it's a Seasonic, duh.
I ordered two of these, one for a customer's build and another for myself. My only minor complaint was that the ATX main and CPU cables were difficult to seat entirely, quite a it of effort was needed to get the locking clips to engage. Other than that this model is quiet, delivers clean, steady, reliable power with decent efficiency. It's the kind of component you can install and then never worry about again.

1 out of 5 eggsYou have got to be kidding SeaSonic...

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: None

Cons: This is an update to my previous review. Unit failed after 22 months. Went through the RMA process. Sent my unit back WITH EVERYTHING CABLES INCLUDED and SeaSonic returned JUST a PSU. Nice... What am I supposed to do with a modular PSU with no cables? At this point there is nothing they can do to repair this situation. I'm through with them.

Manufacturer Response:

Hi Todd, I am sorry for the mixup with the cabling. RMA for Seasonic USA will mean to send in only the PSU. Please let me know your RMA number and we will sort this out for you as soon as possible. Please write to: newegg@seasonicus.com Thank you.

1 out of 5 eggsNice while it lasted

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: Quiet.
Did the job nicely until it failed 22 months later.
5 year warranty.

Cons: Failed in under 2 years.

Other Thoughts: RMA'd it today. That's 20 bucks in shipping and a half hour at the post office I will never get back. Will update the review if and when SeaSonic replaces it.

Manufacturer Response:

Hi Todd, I am sorry for any inconvenience this may have caused you. We do our best to ensure top quality but at times, one single component may fail which will lead to the failure of the unit. I am glad you have started the RMA process with us and if you have questions or concerns, please do let us know by writing to: newegg@seasonicus.com Thank You.

5 out of 5 eggsGreat company

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: Steady power, lots of connections, free bag (holds the modular cables in the box)

Cons: I had to mount it upside down so the fan guard wasn't smashed against the bottom of my motherboard in my case. Not SeaSonics fault.

Other Thoughts: Well designed, cables look great in my case, steady power output.
