I have the old system which was built around 6 to 7 years back. Itís really old machine which is using rdram on it. The old power supply unit of the system is failed few days back and not working properly. I found some unknown connector in the motherboard which is around six pin connector. I donít know what it is. Now I want to buy the new power supply unit which has this connector to get attached. Can anyone suggest which connector will be compatible with this motherboard?
