This power supply has three rails, distributed like this:

• +12V1 (solid yellow wire): Main motherboard, SATA and peripheral power connectors.
• +12V2 (yellow wire with black stripe): ATX12V/EPS12V connectors.
• +12V3 (solid yellow wire): Video card power connector.

Now let’s see if this power supply can really deliver 500 W.
