OCZ ZS 650W Power Supply

OCZ ZS650The ZS series of power supplies from OCZ were just released this year. The series comes in three different wattage ratings of 550W, 650W and 750W. Today, we will be taking a closer look at the 650 watt model. The ZS 650 is a single 12 volt rail model that boasts an 85% efficiency rating. Lets see how well it stacks up against the other heavy hitters that have come across the test bench.

Closer look

The ZS 650W is a non modular power supply. The unit has a nice semi-flat finish, with your typical black color. The combination of blue and gray that line the sides of the unit adds a nice cosmetic touch to it. I would say the ZS would look good in an all black case with an ASUS blue and gray motherboard. Just a thought for those that like to have things match inside the case.

The sticker on the ZS graces both sides of the unit. No matter how the unit is mounted, the top of the case or the bottom, the sticker faces upward and readable. The sticker states the series name and the wattage of the unit.

In order to keep heat in control, OCZ deployed a 135mm cooling fan that is load and temperature controlled. The fan is an eleven blade model and if you are looking for something quiet, this model is not extreme-quiet but well within a tolerable level. In a gaming machine though, you will hear other components over this power supply.

The specification sticker is attached to the top of the power supply. The numbers are pretty respectable especially the single 12v rail which has a total of 46A. Combined with the wattage, the ZS650W should be enough power to push a dual-GPU system with moderate gaming cards. [Editor’s Note: While I agree, it’s worth pointing out that the ZS 650W and 550W models only come with a single 6pin and 6+2pin PCIe power. So if you do want to run with a second card you will have to settle for two Molex to PCIe adapters, but if you are buying a new PSU it’s best to just get one that suits your needs from the get go. Something to keep in mind.]
