Zalman ZM600-ST Power Supply Review

Power Distribution

Figure 14: Power supply label.

This power supply has two +12 V rails (the monitoring integrated circuit really provides monitoring for two +12 V channels and we could clearly see the two current sensors installed on the printed circuit board, see Figure 15), distributed like this:

• +12V1: All cables but the video card power cable.
• +12V2: The video card power cable.

This distribution is perfect, as it put the CPU and the video card on separated rails.

Now let’s see if this power supply can really deliver 600 W.
