Power Supply Trouble Shooting: Not enough connectors for devices

Symptom:
You don't have sufficient pwr connectors for all the devices you want to install.

Probable cause:

• PS is undersized for your needs.
• Or, less expensive PS sometimes come with just a few connectors

Solution:

• Replace the PS if it is undersized
• Use a Y adaoter to split the existing connectors if the PS is rated to handle your selection of devices.

The mobo is connected to the PS with either one or two connectors.

• Older std is two connector system. They were NOT keyed, so you could connect the plugs wrong, or backward, and damage the mobo.
  
• Single Power Connector is the new std are keyed. You can't insert them incorrectly (unless you use a hammer). The above image shows a single power connector on a mobo (the white plastic keyed slots).
