I have a 420 watt power supply with a 20 pin moboard hookup and need to connect to a MSI 24pin moboard...............MSI manual says it can be done, but can't figure out the pins on the power suppy without a schematic or something?

Does anyone know what the improvement is with the 24 pins?

If it can run on 20 only, why bother with the extra 4? If there's an improvement what is it, and how it it that it's optional?

So you don't have to plug in the 4 pin to the left of your CPU.

Ummmn so it's just redundant?

Why then would a modern PSU have both connectors?

todays high performance tech demands more power those extra 4 pins give even more power to the board. Now a converter just splits up one of the 12 volt lines now you don't need the converter to run but some people have had problems without it. Try it without the converter if you get stall ups a it frezzes and crashes then spend $2 for a converter instead of getting a new power supply.

Don't confuse the square, 4-pin CPU power plug with the extra 4-pin plug that mates with a 20-pin to make it a 24-pin mobo power plug. What PSU do you have and what do you have connected to the mobo?

Wrong, modern boards use both a 24-pin for onboard devices and slots, plus either a 4 or 8 pin for the CPU.

Correct Uber, the extra pins are there to supply extra power to the motherboard, necessary with some PCI-Express cards because the x16 slot is capable of delivering more power to a card than the AGP slots were.
