Even if the kit says it only pulls ~4w from the power supply I wouldn't necessarily trust it to run off the motherboard.

I prefer Molex for anything that relatively draws a lot of power.

as in so you can connect it to the motherboard fan headers?
I wouldnt reccomend it as the cathode will probably pull more amps than the headers can supply possibly damaging your board

If you bought it from FrozenCPU is should have had a molex connector already attached. Contact them for a replacement.

Its easy. Just strip ~1/2" from each lead, slip some heat shrink on and twist the leads together. Then hold a soldering iron against the twisted wires for a few seconds and then feed a little solder between the wires and soldering iron (where the soldering iron is touching the wire). Slip the heat shrink back over the wire and apply some heat (a lighter works well to shrink it). Do this for each wire.

PWM? Do you mean a motherboard fan connector? I'm not sure if that will provide the necessary voltage (cold cathodes need 12V) or amperage.

False. They offer the "Stereo Terminal Style" connector for $2 less as an option. My guess is that he inadvertently clicked on that option. If you check the page on FrozenCPU it's the second option. Molex is standard option though.

Ah that makes sense now. I was wondering why FrozenCPU would sell it like that. Still an easy fix.

Yeah, definitely.

Google how to solder OP. It's simple as hell.

I don't think you even need to solder? Can't he just cut off the speaker-style extension, keep track of which wire lead to the red terminal and which to the black on the speaker adapter, then strip the plastic sheath off the wires, crimp some pins onto them and put it into a molex terminal, making sure black goes to black and red goes to yellow?

You should be able to find molex terminals and pins at radioshack for like $4 too.

Sure you can. But it'd be easier and cheaper to salvage spare parts that may already be laying around.

I couldn't find the parts necessary on Radio Shack but Jameco has them.

Personally I buy this stuff from my local electronics store Sandy's Electronics. They are much better stocked than Radio Shack. Look around I'm sure you can find a similar shop near you.

Thread Starter 
Thanks for all the help guys. I've figured out, after thinking of how to get away from the soldering idea (lol), that all I simply need to do is get a molex adapter and take the female part off, leaving me to put the yellow and black wires into my stereo connector thingy. I'm pretty sure this should work with no problems. I have a spare molex adapter laying around, but I may wait 'til later in the week when my brother-in-law and I go to hit up Fry's.

Btw, I got this from Performance PC's. They give you the option to let them do all the work for like an extra $8, but I didn't even realize this was a problem because I just saw the thing and bought it.

I learned my lesson...

Lastly, all of you will be rep'd for your contributions, just not while I'm using my phone, lol (this will be the case until Wednesday, at least). I'll stay subscribed to this thread until I work this stuff out AND I rep all of you who've helped (or at least expressed concern), and I think everyone fits that bill thus far.

Dammit, that's too simple a solution. I should have thought of that that.
