Zalman ZM770-XT Power Supply Review

Power Distribution

Figure 13: Power supply label.

This power supply has four virtual rails, distributed like this:

• +12V1: ATX12V/EPS12V connectors.
• +12V2: Video card power cable from the modular cabling system.
• +12V3: Main motherboard, SATA and peripheral cables.
• +12V4: Video card power cable that is permanently attached to the unit.

This distribution is also listed on the power supply label (not shown in Figure 13), which is great.

This distribution is perfect since it keeps the CPU (ATX12V/EPS12V connectors) and each video card power cable on separated rails.

Now let’s see if this power supply can really deliver 770 W.
