Thanks for the review, as I'm sure I'm not the only one wondering about the M1/M2 choice. The main problem the M2 has? The M(1), as it is a comparable unit for much cheaper. I'm sure CM will rectify by killing the M(1) though. As noted, the price overall is the biggest niggle. The flat, rigid cables and Bronze 80 Plus rating don't add up in my eyes, but these are just little things.

I'm curious about the lower power units though, as the manfacturer is apparently different, as in not Enhance.

I've used a few M1 units I like the flat cables myself (well worked well for my builds)
No problems to report been reliable and quiet units. I see the price has gone up a bit on the M2 units..maybe that will drop down a bit over time.
CM make some decent PSU's quite easy to recommend them having used a few.

So it might be a little pricey... but how about the review sample at $75? See... viewtopic.php?t=47169
