Antec NeoPower 650 ReviewFormer staff writer -
Installing the power supply is a pretty straight forward affair as long you take your time and make sure all the cables that need to be connected are secure and tight. You will also want to make sure that the cables are not routed along any sharp edges when you are doing your wire management so there will be no future problems with electrical shorts. Start by powering down the system and unplugging the main power cord from the back of the installed power supply. Open up the sides of the case to access the internal connections on the motherboard and components. Remove the four screws currently holding the power supply in place. Make sure none of the cables are hung up on the internals, and remove the power supply. Installation is just the opposite. Place the power supply in the cage and secure with the four included screws (in this case I am using thumbscrews).
Once the power supply is secured, route the cables to the components, and plug them in. The NeoPower 650 only comes with four SATA connectors, which by today's standards, are not enough. This build has 2 SATA hard drives at the bottom and a SATA DVD-RW up top. The only way to route power to the DVD-RW was to install a Molex-to-SATA adapter. Connect the main wires to the motherboard headers. Check to make sure that they are all connected securely and you are ready to power it up.
