That is the unit I'd use in my next build. I've had many issues with power supplies in the past, mostly crap brands though. A few years ago, I purchased an Enermax 460 watt power supply. That power supply is still going strong today. Never once have I had a single issue with that unit. The quality of that unit elevated Enermax to the top of the list for me.
I was actually looking at Enermax power supplies last night. I'm thinking about upgrading my build.
Enermax power supplies tend to get solid ratings from the few sites that know how to properly review power supplies, [H]ardOCP being one of them. Some sites just measure the voltage on the rails under load and call it a day. Those solid reviews are a good enough reason to get one in my opinion. It's never a good idea to skimp on a power supply. Bad things can happen.
Enermax Platimax 850 is definitely on the list for the Bulldozer build coming up. Going to need the high wattage for extreme overclocking and the modularity for case organization for this build.
In honesty, I would likely go with a NAXN series. They are great power supplies for the price and I am currently using a NAXN 450w in my rig (see sig).
Of course, if I win that 850, it's a no brainer to what I shal use
I would use the 1200W, as it would provide plenty of power for the multi-gpu setups that I like to utilize, as well as maintaining more stable levels of power for my overclocking needs.
I would probably go with the 1200W Platimax. When I build my next rig, I'll definitely want 1000W+ by that time and I'll have a stable job (hopefully) to afford an 80+ platinum instead of bronze or something.
It would be the Platimax 850W power supply. As for why, because it would have been given to me and the only power supply that I have that is not being used.
Platimax 850 would offer my new build the luxury of clean, quiet and efficient power at a great price!
Have used Enermax in my setup since my son turned me on to their power supplies about 5 years ago.
Great Products!
