OCZ Technology ZS Series 750w Power Supply Review @ OCIA.net
 

Today we will be looking at OCZ's current budget power supply, the ZS series 750w PSU. We got our first glimpse of this unit way back at CES 2011 when we toured OCZ's upcoming product line for this year. The ZS series features a single 12v rail construction and a modest 80 Plus Bronze certification. OCZ sent over the 750w unit but you can also elect for less powerful 550w and 650w flavors should your hardware not require as much juice.
