PC Stats posted a review on the Seasonic M12 700W Power Supply

Seasonic hasn't done anything revolutionary with its M12 power supply, it just put together a very high quality package with a 700W rating. With a retail price of $240 CDN ($214 US, £113 GBP) the M12 700 is certainly expensive, but dare I say, it is probably one of the best modular power supplies on the market. Based on our past experiences with Seasonic power supplies, we know it deliver the goods efficiently - a modular design simply sweetens things.
