24-pin question

I got a set of bitfenix cables, but when trying to put the 24-pin in cable combs, I found that one pin had no cable attached to it and another had two coming out of it. Is that normal?

That missing pin shouldn't power anything these days so it's have been removed, so that's not a problem.

That's the pin that carries -5V for older ISA cards, thus it's not needed anymore.

About the two coming out, you may be referring to this older 20+4 board ATX power cable.

Some PSUs come with a 20+4 cable which is compatible with both 20 and 24 pin motherboards.

So, if you attache the two pieces of a 20+4 power cable together, then you have a 24 pin power cable which can be used on a recent 24 pin main power board.

aha! So there should be a 24-pin too, right?

If your PSU is an older unit it may have the 20+4 pin board power connector.

If you attach the 4 pin to the 20 pin power cable, you get the whole 24 pin connector, that you can connect to the board then.
