The enermax power supply is a 80 plus platinum power supply which means it will have a higher amount of efficiency over the gold power supplies. I don't know much about the silverstone psu I have seen the enermax platimax around if you were however going to go with a gold 80 plus I would go with this one.
The Silverstone units are made by Enhance Electronics and the Enermax units are actually made by Enermax. Both lines are very highly rated. I agree with dish_moose, either would be a great choice for a high quality build.
Guys I was thinking the same thing both are good. I have a silverstone zeus 650 watt that is runnign good for many many years. My doubt was the rails. Silverstone only has single rails now,The enermax has 4 like my old silverstone. I am doing a slow build up, Thinking Rampage iv with 64 gig memory and extreme processor. I was reading allot and many debates on single versies multiple rails for safety protection of parts. Both have same dimensions. Its a 50.00 difference but the silverstone raven 3 case i got for this build of course recommends silverstone power supplies.
Yea I don't think you could go wrong with either power supply you suggested. I wouldn't spend the extra to get to 80 plus platinum unless it was something you really wanted. I have a corsair ax850 and I love it its a single rail power supply I'm not sure what the ups and downs are but I know there are plenty of large 12v single rail power supplies out there.
