Lately we've been trying to focus on mid-wattage units as they seem to fit the needs for a majority of users who have up to a pair of discreet video cards. It's nice to look at the top end hardware day after day after day, but it is always nice to go back to something more for the masses. It helps keep things in perspective with what people can actually afford and need versus what they dream about and will never have a use for.

We decided to do double duty with this latest unit from Seasonic. Most of the power supplies that we have looked at from Seasonic are well towards the full enthusiast spectrum in that they are very high quality power supplies that exhibit superb performance but they always come at a cost.

The M12II EVO Edition power supply is meant for those who want the Seasonic quality, but don't want the price. It gives a little on performance, but gains a ton on the price.

We've seen this many times before and it sometimes has bad results as too much is shaved in order to save more money. Let's check out what the M12II-750 EVO Edition from Seasonic has to offer and if they've found a solid balance with price and performance or if they've gone too far.

Specifications, Availability and Pricing


Seasonic keeps things simple with a single 12V rail. It is rated for 62A or 744W. Both the 3.3V and 5V rails are rated for 25A each with a combined maximum output of 150W. The 5VSB rail is rated for 3A or 15W. Maximum combined output for the Seasonic M12II-750 is 750W.


Just as you would expect from Seasonic, the power supply is chock full of features. Protections are often the first to be slashed when cutting costs, but all protections are present including over-temperature protection. The power supply is fully modular and all cables are either fully sleeved or of the flat ribbon type. The Seasonic M12II-750 EVO Edition is rated for 80 PLUS Bronze efficiency. Finally, while Seasonic doesn't rate the unit for 100% continuous output at 50C, they do rate it for it at 40C.

Seasonic lists the M12II-750 EVO Edition with an MSRP of $99.99. This makes it a very comparatively priced power supply and priced right in the middle of the road. Shopping around won't save you too much, but Provantage does have the unit in stock for $98.87 at the time of writing. Seasonic backs the M12II-750 EVO Edition with a five-year warranty.
