What the Critics are Saying About the OCZ ZT Series
| || |
"It's hard to knock a PSU that's fully modular. Furthermore, this unit has a very good variety of connectors for its wattage and still comes in at only 175mm deep. This PSU does exactly what it's advertised to do, is full modular and comes in at a great price."
| || |
"The OCZ ZT Series 650W proved to be a flawless power supply, with high efficiency between 82.1% and 86.8%, voltages closer to their nominal values all the time (3% regulation), very low noise and ripple levels, and a fully modular cabling system."

"The ZT is built well, sharing some similar external design aspects such as the solid chassis and even the cables are reminiscent of the higher spec unit. In terms of performance this model in the ZT family does well."
