You should try either DiabloTek, Corsair, or Cooler Master. In my opinion CM is a fantastic brand and they're not expensive. This is the PSU regularly use in my build for myself and my business. I strongly recommend it for long-time use

Good luck!
No on Diablotek and Coolermaster PSU's - they are BAD!
