Internally we discovered that Z Series 1000 W is based on the same project as the 850 W version but with one additional active PFC transistor and upgraded rectifying bridges.

We saw efficiency between 87.8% and 89.6% when we pulled up to 800 W from it. But at 1000 W efficiency dropped to 84.3%, but this may also be caused by the different load pattern we had to use to overcome the limitation in our load tester (see our full test results for a better explanation).
Did OCZ send two units one 850W and another 1000w to test???

Why continue to test 1000W units when the test equipment is inadequate to stress the 12 volt rail of this size PSU??? Maybe you should have tested the 850W unit instead???

Updated on March 12, 2010: OCZ has just dropped the price of this power supply to USD 244 at Newegg.com (USD 214 after a mail-in rebate), which is also offering free shipping now. This improved a lot the cost/benefit ratio of this product.

Yes. We've just posted the review of the 850 W version:

We keep telling manufacturers to not send us anything above 900 W but they keep sending them anyway...

We've just tested the 850 W model, see above.

Cheers,
Gabriel.
