Power supply delima

[broken PC]

OK I bought a new power supply today because the new video card wont function without it. There are two problems.

1. There is a 3 pin plug right next to the main mother board plug

2. My speakers run off of DC current power supply that is built into my old powersupply.

I have an older Sony Viao PCV-1132. Any help or insight would be very helpfull.

Those must be some very old speakers to require the old power supply to function. I suggust you just buy some new speakers or a headset.
