Zumax 950 Watt X4 Review

Closer Look:

After pulling the Zumax X4 950 from its protective cocoon, the fit and finish of the components can be seen. Speaking of finish, the Zumax 950 is covered in what the company calls a "Black Nickel" finish. As you can see, the unit is a non-modular design.

 

 

 

 

 

 

 

 

The front facing side panel lists each of the specifications and the current capacity of each line. The X4 950 is cooled by a thermally controlled 120mm blue LED fan that brings in air from the bottom of the power supply. The air is then directed through the back of the unit. Looking at the back end of the Zumax X4 you will not see a switch to manually change the incoming voltage. There is no need as it is done automatically. In addition to the on/off switch, there is a green button on the rear panel. This button is called the Turbo Fan switch. This device switches the fans connected to the fan headers of the power supply from a low noise low voltage state to a higher voltage, high performance mode to provide additional cooling for the chassis. You can now have it both ways, low and slow for a noiseless chassis or flip to the high performance mode for additional cooling - albeit with the associated noise penalty.

 

 

One thing you should never do is to open up your power supply. Several concerns are raised; first and foremost is safety, and second is the warranty of the power supply. In order to help preserve the warranty of the end users and answer questions about the components used in the Zumax X4 950, I will open this one up for inspection. The things that first catche the eye are the 120x25mm blue LED fan and the heatsinks used to cool the regulation circuits. The fan is manufactured or distributed by Globe fans and pushes out 94.92CFM at 2800RPM. The noise level at this fan speed is 43dBA, hence the Turbo Fan mode.

 

 

 

The primary side of the power supply features several large capacitors and coils, while the secondary side contains all of the cable connections.

 

 

Zumax has you covered when it comes to connectivity. 20+4pin ATX, 8-pin 12v EPS power, ATX 12v 4-pin, 1 x 6-pin physics, 2 x 6-pin PCI-E, 2 x 6+2-pin PCI-E, molex 4-pin, floppy 4-pin and SATA. There are three headers that are designed to be used exclusively for the chassis fans. These are tied into the Turbo Fan switch that, when activated, drives 12 volts to the fans to gain maximum cooling performance when needed. Since it is not a modular design, the downside is that while the connectivity is available, you need to hide the unused cables.
