NEWBIE: Case connectors to Mainboard

with a gap in the middle. Here's roughly what I'm talking about:

Question is, can I just pull the wire out of the 3rd position on the
connector and push it into the middle one, and then plug the whole
thing into the mainboard? What's the right way to do this?

You can do this, certainly.

Make sure that you have identified the correct header (that's what the
prongs are called) for the Power LED cable.

Also, on some motherboards there is an alternate Power LED header that will
accommodate the three 3-pin connector. Check your motherboard manual.

Note: You cross-posted to alt.comp.hardware.homebuilt. That newsgroup is
for people who design and fabricate their own computer hardware, although
you wouldn't know it from scanning the headers. :-)

Followups set to a.c.h.pc-homebuilt accordingly.

ignore the rest, BigJim was right, pull back the little tab, the wire slides
right out and you can put but back in the center spot. just be sure to move
the right one because you probably only have extra space on one side for
that now empty side of the connector and the light wont go on if you're
forced to connect it the wrong way.

Hi all:

I'm working on putting together my first system. Almost done, with
considerable help from those on this forum. Many thanks.

One final question:

jumpers on the mainboard. However, the two "prongs" (sorry, can't
think of a better word, though I'm sure there's a standard) on the

Thanks in advance.

Hehe Woody, you've just explained why I cut the empty bit off...

but then what do you do when you want to put a new motherboard in that case
and it needs the 3pin connector? you almost always have space on one side to
leave the extra pin hanging over.

A valid point. I've never had this situation arise as yet but it may be
worth reconsidering my technique in light of that possibility...
Thanks.

Thank you all for the tremendous response. I tried BigJim's idea. I
did manage to destroy the flap at one end, but the middle flap was
fine, and it worked, thanks to the great suggestions.

Out of curiosity, can you buy those little connectors retail? In the
Bay Area, for example, could I walk into a Fry's store and ask for
them? What are they called anyway?

Well, in the UK you could go to Maplin and ask for these:

and some of these:

Hey Jeff

He is talking about the Power LED whick blinks when the hard drive is in
use.

He is NOT talking about a FAN LED!

Usually called "pins". Same thing.

on the
mainboard are adjacent, whereas the wire from the case is 3-wide,
with a gap in the middle. Here's roughly what I'm talking about:

One of the 3 connectors if for the RPM sensing of the fan. If you don't
need RPM sensing, you don't need 3 wires. But you do have to make sure
the
2 wires that get connected are the power wires, and you should note the
polarity. If you get the polarity wrong, the fan will spin backward.
That's OK if you can flip the fan around, but it won't work if the fan can
only go in one way.

I sure don't know where I got the idea he was talking about a fan. I must
have had it on my brain from another thread or something....

And, incidently, reversing the polarity of a fan won't make it run in the
opposite direction.
