SeaSonic Electronics launches the M12II "Bronze" Series, the new and upgraded version of the M12II Series in response to the growing demand and anticipation for more energy-efficient products.

The M12II Bronze Series, available in 520W and 620W, offers buyers with a mid-range power output solution with cable management to meet their exact system needs—cable management is now made easier than ever.

Such designs and components including Double Forward Converter design, Smart and Silent Fan Control and highly reliable Japanese-brand capacitor also boost the overall performance in stability and silence. The M12II Bronze Series is available in a standard ATX Form Factor and in wattages that are beneficial for a PC system.

Moreover, the modular design also provides a flexible solution for orderly cable management.

Solid Offering

Pros: Modular,
Wrapped power lines,
Quiet operation,
Extremely affordable with rebate

Cons: There was a little bit of guesswork with the cords at first, but in about 15 minutes I had swapped out my old power supply with this and really enjoy it.

Overall Review: This is my first build using a modular power supply, and I'm glad I made this purchase.
The power supply worked like a charm and the wrapping on the power cords are attractive.
With my video card and cpu fan on I really can't even tell it is there.
Thanks for offering this power supply at a reasonable price. (mail in rebate was icing on the cake)

Dead On Arrival! Trips my circuit breaker

Cons: DOA!
Trips circuit breaker and doesn't work!

Overall Review: I read a lot of reviews saying that they got a defective product. Some even said they got a defective product 2 times in a row. Guess what? I also got one. My EVGA PSU works normal (500w). I bought the 520W SeaSonic and it trips the circuit breaker every time!

BAD LASTED ONE MINUTE

Pros: No pro about it. It lasted only ONE minute. Then it began to click 3 times an gave up the ghost.

Cons: Don't trust Seasonic. I think NewEgg has them on sale for a reason!

Overall Review: Do not recommend it.

solid PSU

Pros: no ketchup and mustard cables
fully modular
price

Cons: not the most quiet

Overall Review: I couldn't find a better power supply at this price point. Fully modular, ATX, black cables, from a reputable manufacturer, and to top it off its 80+ Bronze rated for only 68 buck including tax. Perfect for any mid range systems. Definitely earned my recommendation!
