David... Most new motherboards have a second connector (12V yellow/black)

which has to be plugged in for the system to boot up. Some graphics cards also have an extra power connector, also 12V yellow/black which looks similar to the type for the motherboard. Some early graphics cards had a standard 5V/12V four pin connector. These two yellow/black PSU leads can be plugged in back to front by mistake which prevents the PC from booting up. Both are only available on modern PSUs. Allan G3PIY -----Original Message-----

I think I'm getting my money's worth out of it.Do some graphics cards have a second power supply connection? I've seen this with satellite TV tuner cards. Just wondering what might happen if the second power lead hadn't been connected.... David GM8ARV -- SatSignal Software - Quality software for you Web: https://www.satsignal.eu Email: david-taylor@...
