Today HardwareHeaven are going to have a look at a model from the best power supply family OCZ has to offer, the Z Series. The Z Series consists of only two units at this point of time and it is the 850W model which we will review today. OCZ must be very confident about their Z- series, claiming boldly that these products are "nothing but the best". In this review HardwareHeaven are going to put the Z Series 850W to the test and see how well this unit can really perform.
