Seasonic M12II Bronze Series has been the ever-popular power supply series of the semi modular category. Now Seasonic extends the semi-modular series by introducing M12II Bronze 650/750/850 to provide consumers a larger selection in the entry level 80PLUS Bronze certified category.

The all-new M12II-650/750/850 units are the new leaders in the 80 PLUS Bronze category and another great addition to the Seasonic Retail power supply family.

5 out of 5 eggsNice PSU

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: Semi modular is great.

PSU runs quiet.

Seasonic is the best in the industry for PSUs.

Runs cool also. I am running an AMD FX-8320 with an ASUS R9 270X if anyone is curious.

Cons: None.

4 out of 5 eggsWorked Out

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: Organized,
great reviews from outside sources,
fits well in my mid tower, slid right in,
good amount of power for what I use my computer for,
far and away a huge upgrade from my PSU that came with my case.

Cons: Cables can be a little weird to work with. I suppose I could space out my drives a little better.

Other Thoughts: I have a pretty meager system to install a 620w PSU into:
Older Gigabyte motherboard
4gb DDR2 (2 X 2gb) Kingston Hyper X
Phenom II 965 3.4ghz PIB
GeForce GT 430
WD Black 2 TB HDD
WD 500 GB HDD
Lite on DVD Burner
Cheapo Wi-Fi card

Looked at the 550w but the 620 was actually cheaper so...

5 out of 5 eggsWill always look at Seasonic 1st

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: Replaced a PS in an HP Desktop, with multiple drives and multiple optical drives using a video card that required 130W was too much for the little power supply. This one fit the bill. Look at all the review sites and you will see Seasonic consistently rated high. There is little reason to spend more. It also runs very cool so the fan does not need to push a lot of air, making the whole PS very quiet.

Cons: None so far.

2 out of 5 eggsOver too fast

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: Huge suite of connectors. Flexible, durable cabling. Quiet.

Cons: Popped and died on me a little after a year.

Other Thoughts: Fired up the machine this morning and this PS popped and died on me. I haven't had it much longer than a year so this was a real disappointment.

Manufacturer Response:

4 out of 5 eggsGreat, Reliable Power Supply

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 high quality power supply. Has never failed my system once. Semi-Modular, so I can put away cords that I don't need. Barely Audible.

Cons: Somewhat expensive, but it's absolutely worth it. The last thing you want to burst in your computer is the PSU. Barely Audible.

Other Thoughts: Overall, A great PSU for the price. Recommended.

5 out of 5 eggsworks fine, not fully modular

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: 80 bronze, plenty of juice for an i7 4770k, 120gb sammy ssd, 1tb WD Black hdd, 16gb mushkin ram, asus z87-plus mob, asus dvd/cdr burner, asus bluray burner (added later), and enough left over for 1 or 2 GPUs. solid overall. no problems yet.

Cons: not fully modular, but honestly, those cables are necessary anyway, so really not a downside.

Other Thoughts: wait to see if this lasts, but so far no problems at all.

5 out of 5 eggsa no non-sense PSU

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: Semi-modular design makes cable management a breeze.
Plenty of power for my gtx 770 system
Not flashy
Feels well built

Cons: none

Other Thoughts: A basic, user friendly, psu. Bought this for my first gaming pc build and it was a very easy to setup. Love the modular design. comes with plenty of connectors, and a nice cloth bag for unused cables. Not as flashy as some other brands but that is my preference

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: A year and couple months ago, I built my first pc, and it still run like it was yesterday. I like the feature that you can unplug the cables that you don't need, my tower is big, so, this is not a problem! It runs quiet and smooth.

Cons: None

Other Thoughts: Had it for more than a year, and I have 620W.

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: Semi-modular
Seems well built
Looks good
Quiet
Still working (bought Oct 2012)

Cons: None so far

Other Thoughts: I had it in an older case where it mounted at the top of the case. When I went to move it to a different case and computer setup, I had to pull the heat sink off to get it out of the case. Just something to keep in mind.
