Power Distribution

Figure 16: Power supply label.

This power supply features four +12 V virtual rails distributed like this:

• +12V1: SATA and peripheral power connectors (modular cabling system) and main motherboard connector.
• +12V2: ATX12V/EPS12V connectors.
• +12V3: One of the auxiliary video card power connectors (modular cabling system).
• +12V4: The other auxiliary video card power connector (modular cabling system).

We think this distribution is perfect.

Now let’s see if this power supply can really deliver 550 W.
