What is the difference between 20-pins ATX power cables and 24-pins ATX power cables for motherboard? I see that Cooler Master Silent Pro PSU has an extensible plug, showing 20 pins + 4 pluggable pins.

Since I'm having troubles with my motherboard, which has 24 pins, I tried to connect only the first 20 and the system booted up fine.

I'm curious: can any ATX motherboard run with 20-pins power? Will I simply experience lower performance?

I have a reasonably-decent old 20-pin PSU which I want to use on a newer 24-pin ATX motherboard. I see that the ATX page on wikipedia mentions that 24-pin ATX is backward-compatible, and I can find 20-to-24 pin adapters to buy for a couple of dollars/pounds at lots of places, but I can't find any… >>> More
