Seasonic M12II SS-500GM - Overview


Seasonic didn't make a lot of noise about their second M12 series when it launched a few years ago. It was a follow-up to the original M12, which included a second small fan to help with cooling. The latest M12II uses a single 120mm fan, which is good since it reduces the acoustical noise and limits the number of points of failure. We're not sure why Seasonic didn't advertise this series more, though it might have something to do with the lawsuit by Ultra against anyone with the cable management system.


This power supply has been in the market for some time now, so it uses a Hitachi capacitor in the primary with Nippon Chemi-Con secondary capacitors. Hitachi capacitors are seldom seen these days, as they tend to be more expensive. The heatsinks consist of metal plates stamped into the appropriate shapes, and as always Seasonic uses an Adda fan for cooling.

    Excellent!! I am curious as to how those solutions compare to standalone "standouts". I think the days where we see some no name powersupply that isn't very good in systems (as a general rule) are gone. That's been replaced (in North America) now with seeing solutions by Antec, Fsp, ect as the standard. So the comparison's are of interest.

    Any idea when any "Gold certified" ~500W PSU's will be available (on Newegg, or another online vendor)?
    Such as:
    Thermaltake W0338 TP-500AH3NCG 500W
    Seasonic SS-550LT 550W
    Channel Well PUK500V-G 500W

    I think we will see first units in summer.

    I'm looking for a cheap 450W - 550W Powersupply (cheap but still a bit decent, around 50 euro), so I was really interested in this article...

    Unfortunatly the only PSU in pricerange, the Artic Cooling, is unfindable in the Benelux (EU). Also the next in price (Tagan Superrock), which actually is too expensive already, is unfindable here...

    so I still don't know what to get

    Buy an Enermax 525W, they were tested earlier here on anandtech and are very good PSU.

    They should be available easily in Europe :)

    cheers

    Thanks for the tip, but those enermaxes are again waaaaaaaay above budget (89+ euro!!)

    The Corsair CX400 is 43 euro
    That Artic Cooling 550W is 68 euro (shipped from DE)

    I'm looking for something in between... (around 50-55 euro)
    like a decent 450-500W Powersupply...

    Corsair VX450 or HX450 (we unfortunately do not get the HX450 in the States :( Sad because it's 80+ Bronze)

    Sounds like you are looking for a (very) good *and* cheap PSU.

    That is imo impossible. You either get cheap China crackers or good, expensive ones.

    Do you *really* need ~500W ?

    If not then try the Enermax 425W. That is my last idea, otherwise I would suggest to raise your budget :)

    cheers

    no, you're wrong...

    the Corsair CX400 apparently isn't that bad and is VERY cheap...

    I'm willing to pay a little more for a little better, but it seems like paying a little more will only get me worse :(

    Paying A LOT more does get better though, but then I'm over my budget for the pc i'm composing...
