Features [ Edit | History ]

M12 series power supplies are with detachable modular DC cables. Designed for Do-It-Yourself (DIY) system builders, gamers and Over-clocker enthusiasts, the M12 is available in three power levels, the M12-500, M12-600 and the M12-700. They provide stable power for high end, high performance graphics applications.  Each model provides system builders the flexibility to create the most suitable combination of connectors to minimize clutter and optimize airflow in their PC systems.

M12 series is built to the highest quality and specifications. The double forward converter circuit design coupled with active power factor correction ensures that these power supplies achieve the highest efficiency ratings in the industry. Additionally, Seasonic’s proprietary dual magnetic circuit design enables the M12 power supplies to maintain a tight 3% tolerance on the all important 12VDC output line which is so critical to gamers and Over-clockers who seek stability even at maximum system loads.

Another unique feature that sets the M12 series apart is the extra 6cm ball bearing fan which provides additional cooling and reduction of internal hot spots in the power supply.  Like the main 12cm ball bearing fan, the 6cm fan is mounted on soft rubber grommets and is governed by Seasonic’s high performance Super Silent Fan Control [S2FC]. This special feature makes the Seasonic M12 series one of the most silent and well-cooled power supplies available on the market today.

The Seasonic M12 series fulfills European Union regulations for RoHS, WEEE and major worldwide safety requirements.  These power supplies represent the ultimate in modularity, efficiency, stability, silence and green innovation and redefine the term “high-end modular” PC power supplies.

Experience: 1 Months


Worked Without any problem on the first try, worth to buy it so far
For me the price is abit high but well it is the buyers decision to decide wether to buy or not.
I heard that this thing is not that great.but for more i really like it. I think it was what i wanted to be.

Experience: 20 Days


Solid build, quiet and running stable.
Pricy if not on sale/rebate.
Solid build, quiet and running stable. Really a good buy, especially on sale price under $80, would buy again for another desktop build. come with a PCI-E 8 pin cable (actually 6+2).

Similar to Corsair 620hx
Made by Seasonic
50 dollars (boxing day sale & Such a steal for that price)
No 8 pin pci express cables (not that i need any YET)
60mm fan is pretty useless and adds to the length of it
Bought this on the boxing day sale for 50 bucks (what a steal :D) and worked great out of the box. This replaced a generic power supply that was half dead. Modular cables are easy to sleeve for this power supply and it has remained cool and quiet under many conditions
Awesome price for a quality 600w

Experience: 1 Weeks


Hi efficiency psu, stable rails
can be pricey when not on sale
Had it with combo deal, this and a Antec 300 computer case, and it was a very good suggestion, this psu is running cool and quiet. Voltage is stable and it's modular so nothing but good thing about it......but it come with a price

Experience: 1 Days


modular,PCI-E 8 pin cable
Great deal . it works well. It's quite and 80plus certified for power savings. It's hard to find anything at this price that offers all the features on this.

Experience: 1 Months


-Really good efficiency
-Really good for mid-high end systems
-Modular for less cable clutter
-Comes with a lot of connections
-Good price got it for $99.99
-Loud (to my ears) when a full load
-The back panel connections are a bit loose
If you're looking for a power supply that is cheap, reliable, and convenient then the seasonic M12 power supply is just for you. Its got enough power to juice a SLI(8800gt) system and still some more. I'd recommend buying this power supply only on sales because the price is steep compared to the Corsair HX 620
