Performance is outstanding. It eliminates stability issues associated with low quality and low power PSUs. It runs very quiet, but that doesn't matter because I wouldn't be able to hear it over the screaming delta on my HSF anyway! One thing I really liked is that it has been ATX 2.03 Revision approved for a few months now, while Sparkle Power Supplies have just recently upgraded. What that means is you can use these units with Pentium 4 systems requiring direct 12V power to the CPU. It also has a connector to Server Motherboards and would work great with a server system. I also liked that the black power cord was over 2 feet in length! It comes with great packaging and a 2 year manufacturer warranty.
