This review speaks very highly of it: http://www.kitguru.net/components/power-supplies/zardon/cooler-master-masterwatt-maker-1200-psu-review/
Good voltage regulation, great ripple suppression, quiet. There are quite a few things they didn't test like transient response and hold up time. So I'm curious to see what other reviews will turn up. However it looks like it is going to be very expensive. And going up against heavyweights like the EVGA Supernova T2 1600 and Corsair AX1500i it will have to beat them in price in order to be competitive.
Thank you for the information!
I see that it's entire wattage capacity can be delivered on the 12V rails... I think that that will be a major selling point. It's pretty normal for high quality units to be able to deliver at least 75% of their wattage capacity over the 12V rails, but this is the first time I've seen it at 100%.
I like how there are different fan profiles that can be switched to and from via software. I also like the inclusion of the ability to set a custom fan curve. I think it would be great for all power supplies to include this feature in the near future.
I agree that it will probably be rather expensive. However, I'm not sure that this unit will be targeted at all enthusiasts looking for a 1200 watt power supply... I think it may only be aimed at those who simply enjoy over-the-top tech. They may simply be using this unit, which seems to have everything you could want in a 1200W power supply, to conduct an unspoken public survey on what features enthusiasts will really use. Kind of like how Intel used the boards for the 5xxx series of CPUs to iron out the bugs for when it came time for the 6xxx series. Of course, the applications are different between CPUs and power supplies, but it's the same basic concept.
