OCZ has made a very good power supply with the Fatal1ty 1000W. It's extremely efficient, the ripple values are unsurpassed and the individually sleeved wires give it a unique look. The one area that deserves criticism is the noise production of the PSU. The OCZ Fatal1ty 1000W is not extremely loud, but it could have been more silent especially under light loads.
For just a little more money you can buy the Cooler Master Silent Pro Hybrid 1050W that is just as efficient, also has a very low ripple, but has longer cables and is more silent due to being semi-passive. If you want to spend that much money on a PSU, then the extra money is worth it in our opinion instead of buying this OCZ Fatal1ty 1000W.
However, if you don't care about a little noise, then the OCZ Fatal1ty 1000W is an excellent PSU with 80 Plus Gold certification that case modders will definitely enjoy.
