OCZ ZX Series 850W Modular Power Supply Review

Installation & Testing
Installing the ZX Series power supply into your system is very easy, especially since it is fully modular.  So you are able to run your cables from your devices then connect them to the power supply.  I had no issues getting the ZX Series installed in my case.  I would have liked OCZ to include a CPU power extension for larger cases, it makes installing the CPU power cable so much easier.

Here is a full rundown of our test system for the ZX Series Power Supply.

Processor: Intel Core i7-965 Extreme
Motherboard: Gigabyte X58A-UD5
Memory: Crucial Ballistix DDR3-1866 6GB
Video Card: Sapphire Radeon HD 6950
Storage: 750GB Samsung SATA Drive
Fans: 2x 230mm fans
Case: BitFenix Colossus

For testing we will be using OCCT to stress test the system and log the changes in voltages.  Initial spot checks on the 3.3V, 5V and 12V rails were 3.3V, 4.97V and 12.61V respectively.  Here are the results from the OCCT stress test.

The results were very good, the biggest ripple we saw was in the 5V rail, which was 1.08%.  That is well within the 5% threshold we like to see.  The 3.3V rail was the most stable with only a 0.48% ripple.
