It stays cool, I haven't done any scientific measurements to see if it's actually above 85% efficiency, but based on the fact that it stays cool to the touch I have no doubt that very little power is getting wasted as heat. It's powering an overclocked Core i7-2600K, 16GB of RAM, a Blu-Ray burner, three hard drives, an SSD, and an overclocked GeForce GTX 560 Ti-448 (basically a GTX 570). Looking at the BIOS monitors, I see no voltage drops or fluctuation when overclocking so this little guy is giving me nice stable, clean power.
It's mounted in a Corsair Carbide 500R case, and as would be expected it was easy and flawless to install.
The power supply installed very quickly, was extremely easy to attach all of the wires I needed and all of them appear to be of high quality. The power supply is extremely efficient as well as incredibly quiet. I will NEVER purchase a power supply from anyone buy Corsair, not that it matters though because I cannot imagine having to replace the one I already have.
What this means is that if you put in 3 PCI-e video cards that each draw 75W (through the socket) you will burn the plastic off the ATX connector around those sockets, and then your computer will randomly shut off. I called Corsair to discuss this and they at least said they'd look into it.
If you want to fix it yourself it's not too hard with less than $20 worth of parts from DigiKey. Feel free to comment/contact me if you want the part numbers. It's a a lot cheaper/easier to fix it before you burn the plastic off. (I also have pictures, if you want to see them, I don't think I can link them here. Look up my blog if you want to see.)
I'm still giving it five stars because I know this is really an edge case, but I think it's going to be more common soon. I'll also note I had this happen with a 1kW CoolerMaster PSU. Basically all consumer PSUs use cheap sockets there instead of Molex HCS sockets. Just to give you some idea how silly this is, those sockets cost ~0.50 each (needed: 2) when buying in single-item quantities. It drops to just a few cents apiece when buying in bulk (as Corsair would). How much does a velvet bag cost?
In conclusion, this is a very nice power supply. If it was not for the minor issue of noise and the location of my PC, I would have kept it. I would recommend this product. Especially if you need a high wattage P/S to run your system. If you can get by with a lower wattage unit and want something that is silent, there are other options that are also cheaper. I hope this helps anyone that is on the fence about the Corsair 1200AX.
