24 pin atx power connector with 20 pin??

[gb1217]

i got a MSI "K8N Neo4 Platinum SLI" NVIDIA nForce4 SLI Chipset Motherboard For AMD Socket 939 CPU mobo. It has a 24-pin ATX power connector. I got a case which has only a 20 pin power cord. Would connecting the 20 pin to the 24 pin make any difference and/or will it make the system unstable??... are there any adapter to convert this 20pin to 24 pin....help ASAP!

There are adapters, but many boards just work with out an adapter as seen here.

The above pic is my board that I was running with a 20pin antec psu.
Here's another pic, of my board. I don't know how the neo4 is but on my board the connector would only go in one way.

More important is the amp rating on the 12v rail, and does your current psu have the -5v rail, (which is needed to enable the onboard Creative sound).
