Default New power supply. 20 pin VS 24 pin connector. Adapter needed? Does it matter?

I just swapped power supplys on my computer (went from 200 to 500).

The OLD PS plugged into the motherboard with a 20pin connector (MB has a 20 pin slot on it).

The NEW PS has a 24 pin connector on it. I plugged the 24 into the MB's 20 pin slot and it powered up and is running.

Question
1) Does it matter that the remaining 4 pins are not connected?
2) Is there an adapter that will make the MB's 20 pin slot a 24 pin slot?

Thanks...

What kind of psu do you have?

I know on mine that the last 4 pins break apart from the clip. I'd assume that the first 20 pins have to be the same. I mean the only difference is that on mine they snap apart from the clip, and on yours they might not.
Only issue I could really think of is that the psu clip might not line up and snap down on the motherboard clip. But it should stay in place regardless

It's just the difference between revisions of connectors. Newer mobo's need some extra juice but the 20 pin part of the 24 that plugs into your mobo is compatible, so no worries there.

a lot of the higher-end motherboards require a 24-pin native connection.

I just got a new PSU too and I had the same thing happen. I have a 20 pin MB, so when I opened up the box and saw it was a 24 pin connector and thought "Oh ****, will this work?" I was afraid my system was going to get fried somehow.
