OCZ might have learned something when they picked up PC power which is what I would pick or Seasonic but I tend to look for a power supply I know will last and have a very clean power output and no current dips when power spikes hit. I don't care for budget power supplies because too much rides on their working good. Like the whole computer and it's stability. It has gotten even more important as voltage levels have dropped all over the system and noise becomes even a worse factor.
Don't skimp on the power supply of all parts you buy.
