OCZ ZT Series 650w Modular Power Supply Review @ OCIA.net
 

Late last month we took a look at OCZ's current budget power supply, the ZS series 750w power supply. This unit featured a single 12v power rail, 80 Plus Bronze certification and a hardwired construction. The PSU performed just fine in our evaluation but one thing that many people (myself included) typically look for in a modern power supply is a modular design. Today we have an upgraded version of that power power supply that falls under OCZ's High Performance category, OCZ's ZT series modular power supply.
