A while back I also saw a post by another forum member that showed this is what they used and it almost caused a fire. How can I first of all know if I'm putting connecting the correct wire to the correct side so when I plug it in I wont have the polarities mixed.
The fire was apparently caused by a loose/high resistance connection between the socket and an old power cord.
The C14 socket you posted should work fine.
With power connections, always verify that you have a good mechanical
and electrical connection.
If you want to verify your connections are good, you can use a multimeter to test the resistance from the (unplugged) power plug that plugs into the wall outlet to the power supply connection/power strip. (<2 ohms is good)
If you wire it to a power strip, an outlet tester will tell you if it's wired wrong.

There's a wiki entry
here showing how to wire the connections for the switched/fused inlets.
