OCZ ZX Series 850W Modular Power Supply Review

15 May 2011
  • Summary: Final Thoughts OCZ has put together a very solid power supply in the ZX Series. In our testing the rails were very solid, with only minor ripples way under the threshold that we like to see. The ZX Series has a 80 PLUS Gold certification, which means it will run 87% efficient at 100% load.

  • Cons: – None that I found
