Seasonic a company whose name is recognized the world over as being the last word in near-silent power supplies which perform extremely well under any circumstance. Unbeknownst to many people is that Seasonic originally cut their teeth in the electronics test equipment field before branching off into power supply manufacturing back in 1980. Since the days of bellbottoms, big hair-dos and flower power, a lot has changed with Seasonic; they have opened up branches in the USA and in Europe while expanding their holdings in their native Taiwan and have moved on to almost exclusively produce computer power supplies.

Before the advent of Corsairís ultra-popular HX-series of power supplies, Seasonic wasnít a household name but was still a name recognized by enthusiasts all over the world. Their original S12 and M12 series found many adherents in both the enthusiast and casual computer user alike. Here in North America, Seasonic is better known as being a leading OEM with clients such as PC Power & Cooling and Corsair under their belts. However, even though they manufacture power supplies for numerous clients, Seasonic still maintains a strong presence in the retail market and today we will be looking at one of their newest retail oriented units: the M12II 500W.

While the M12II 500W may be a far cry wattage-wise from some of the bruisers we have been testing these last few months, it allows us to showcase a power supply that should appeal to a much broader market. This power supply is the spiritual successor to the original (and extremely popular) M12 and shares the same modular interface but as we will see later, the similarities stop there. Priced around $120, this is certainly not one of the less expensive 500W units on the market but it is one of the few in this price range with a modular interface. The Seasonic M12II also comes with a warranty length which will make many of its competitors cringe; at a full 5 years, it is one of the longer warranties we have seen in a while. Unfortunately, like all Seasonic power supplies it seems like finding stock of this particular unit here in Canada is a bit tough but if you look hard enough, you should find it for a fair price.

With the pedigree of numerous award-winning power supplies in Seasonicís corner it seems that the M12II 500W has a better than fair chance to be one of the better 500W power supplies we have tested. It should be interesting to see what the tests will hold.
