OCZ Technology has built a reputation for being one of the leading brands in Memory, Solid State Drives and Power Supplies in the computing world of today. Their quality products are backed by excellent customer service and attractive warranties.  In 2007 OCZ acquired PC Power and Cooling which still operates its own line of power supplies to this day. Thanks to this acquisition OCZ has been able to improve and solidify their position in the power supply market. Today we take a look at one of those power supplies. In fact this is their flagship unit, the ZX Series 1250W.

The power supply comes in a well decorated box with a handle, and believe me, you’re going to need that handle as this thing is heavy. Even out of the box the power supply itself feels heavy and that’s considered a very good thing when it comes to power supplies, it means it’s likely made of quality components. Since this is a fully modular power supply there are no cables sticking out of it. Instead these cables are included in a separate box along with the power cable, screws, user manual, Velcro cable ties and 80 plus Gold certificate. The cables are in a small bag and there are a lot of them. Each cable is labeled at each end so you know which side goes into the power supply and what plugs into your computer components. They’re also quite long so you won’t have any issues with cable management.


- 1250W Continuous power

- Ultra quiet 140mm ball-bearing fan

- +12VDC @ 104A Single Rail Design

- SLI™ and CrossFire™ support

- Fully modular cable management system

- 150 x 175 x 86mm (W x L x H)

- ATX12V v2.2 and EPS12V

- 80-Plus Gold Certified

- 92% Efficiency (Typical Load)

-  Overvoltage/Overcurrent/Short-Circuit protection

- Active PFC

-  MTBF: 100,000 hours

- 5 year warranty backed by OCZ’s exclusive PowerSwap Warranty replacement program.



-  20+4 pin ATX

-  Dual 4+4 pin CPU

-  6 x PCIe 6+2 pin

-  12 x SATA

-  9 x Molex

-  1 x Floppy


The power supply can accommodate up to three graphics cards and has a single 12V rail with 104A. Of course, you can’t use all the connectors listed above, but I highly doubt you will need to. The 80 plus gold certificate means it has 92% efficiency under load which is well over the 80% required for the 80 plus certification. The power supply itself is quite nice to look at, with a black finish to prevent small scratches and dents. Overall the power supply looks and feels like it can take on the best and most power hungry components on offer today.

      VRY SRS BRO! None at the office and many PSU reviews just use multimeters. Just not enough come by to justify the expense.
