Seasonic M12 600w Modular PSU
Appearance
Published: 8th November 2006 | Source: Seasonic | Price: |
Seasonic have never been the kind of company to go for funky colours and flashing lights in order to shift their power supplies. As we can see below - this 'no bling' trend has been continued in their M12 series.

The Seasonic M12 is powder coated in matt black paint and has a minimal amount of shine. Contrasting with the black body is a silver fan grill responsible for protecting the 120mm fan installed on top of the unit.
The back of the unit has the usual honeycomb grill as seen with almost all power supplies that utilise a 120mm fan. This allows for the hot air circulated by the fan to exit out the back of your PC case. You may also notice the abundance of a voltage selection switch. This is because the M12 is able to detect the input voltage (110/240v) and switch accordingly.

The sides of the M12 are fairly plain, with one side containing a specification sticker detailing the amperage output of each rail on the M12, along with all the usual certifications and warnings about opening the PSU's casing.
The front of the unit offers a fresh talking point - a 60mm fan covered with a silver fan grill. This was put in place to give airflow to the areas of the PSU that the 120mm does not reach, and also to assist in the extraction of hot air through the mesh at the back of the PSU.

I look forward to the Corsair 620 review if you get to test one, as far as I know it's very similar but is quieter with only 1 120mm fan.

I look forward to that with massive interest, I'm thinking of getting one because of it's supposed high efficientcy and quietness, may I ask if you sell them after review?

Nice review 
You need to upgrade the PSU tester, 10a per 12v is nothin!

If you look at the specs on the M12, the maximum combined amperage it can cope with on the +12v rail is 48a - so i got as close to that as possible (40a). Plus its handy to compare results with other 600w PSU's - most of which have been subjected to the same stress.
Wow, 80a? Impressive.
Thanks for explanation though XMS

Great review, and this looks to be a half way decent PSU. I think I could pick something better to put in my case if I had the choice however.
XMS, you gotta line up a single rail 1kw turbo-cool review!

I am not a fan of the modular style PS.
But that was a very good review.
