Delivery and Specifications


Cable Length
1 x ATX 24 pin 62.5 cm
2 x EPS/ATX 12V 4+4 pin 64 cm
6 x PCI-E 6+2 pin 58 cm
3 x 4 SATA 85 cm (40 cm - 55 cm - 70 cm - 85cm)
1 x 4 pin Molex 85 cm (40 cm - 55 cm - 70 cm - 85cm)
1 x Floppy-Adaptor 10 cm

The delivery found with the OCZ Silencer MK III 750 Watt is good. Even a high-end gaming system or an overclocking setup can be wired seamlessly. It's possible to drive an NVIDIA SLI or AMD CrossFire setup with this PSU and up to twelve SATA devices can be connected to this unit. There is also the possibility to connect two EPS plugs to motherboards, which should offer this feature. Another special feature is the silent mode. Once you flip the switch above the main power connector it is activated. Now the 140 millimeter fan will remain dead silent up to a load of 50 percent or in other words 375 Watts.
