Power Distribution
Contents
In Figure 15, you can see the power supply label containing all the power specs.
Figure 15: Power supply label.
This power supply has six virtual rails, distributed like this:
- +12V1: Main motherboard cable.
- +12V2: The two EPS12V/ATX12V connectors.
- +12V3: Two of the four connectors for SATA and peripheral power cables.
- +12V4: Two of the four connectors for SATA and peripheral power cables.
- +12V5: The two light blue connectors for video cards.
- +12V6: The two dark blue connectors for video cards.
Each rail is clearly indicated on
the modular cabling system. The fifth video card power cable (which has two connectors) can be installed on either +12V3 or +12V4.
Power distribution is ok, although it would be better to see all video card cables on separated rails.
Now let’s see if this power supply can really deliver 900 W.
