A heavy duty power supply that worth its salt.
Below are the components used to test the OCZ ZX 1250W as well as a Cooler Master Silent Pro M 1000W for comparison.
- Intel Core i7 2600k @ 4.5ghz
- Cooler Master V6GT
- Asus P8Z68-V Pro
- 2 x AMD HD 6870 in CrossFire
- 1 x Kingston V+ 100 96GB SSD
- 5 x HDDs
- Cooler Master HAF:X with 5 fans attached
I ran OCCT to stress the CPU, GPU and the whole system, and took results from the 12V, 5V and 3.3V using a multimeter. I also took a reading for when the system was idling.
As you can see both power supplies performed well within acceptable standards with very little deviation and inside the 1% mark. The OCZ did dip lower than the Cooler Master at times but variations can be expected. Overall both power supplies proved to be quite effective at keeping up with whatever was thrown at them. My colleague Taimoor did notice that when he initially tried the OCZ with the office testbed, he encountered a buzzing sound when running the graphics (forest) benchmarks in PCMark7, however, I may not have noticed it with all the fans running at full blast and the case was shut.
The OCZ ZX 1250W proves to be a capable power supply that offers solid performance and is fully capable of handling an array of components. Cable management should not be a problem for any case thanks to the meshed cables and fully modular system that ensures you don’t have too many cables to twist around your system. Furthermore OCZ’s PowerSwap warranty means you get a replacement without having to wait for repair turnovers.
