my power supply is the Antec 500w smartpower 2.0 and my case is a silver stone. the 4pin connector that goes to the motherboard to power the cpu is not long enough to reach, can i splice in an extra 2" of wire off a molex connector to make it longer or is this not recommended? i kind of need to get my computer running and don't want to wait to order and extension.
thanks,
mike

As long as you do a good job making the connections and insulating the wires, you should be fine. Make sure the wire that you're using is the same gauge as the existing wire. I'd suggest soldering the connections and covering them with heatshrink. If you aren't going to solder them, I wouldn't recommend doing it at all.

thats for the fast reply. yeah i can solder them. but this will not cut power out of create power spikes and such?

Now, if you were adding hundreds of feet to the cable, I'd be concerned about the resistance of the wire and all that jazz... But this probably won't be any more than 6 inches, so no worries there. This is also a low-voltage application, so I wouldn't be concerned about arcing or anything else like that either. But since the mobo/CPU can pull a lot of current, you want to make sure that your connections are good. If they're not, you run the risk of heating up the wires, which might melt the insulation and start a fire.

But as long as you make a good connection, it's just like the original wire.

sweet, thanks. wish me luck. but if there is anyone else that would like to give their advice i would be grateful.

i couldn't get any heat shrink, will electrical tape work?

It will work, but electrical tape is more likely to come off over time. Heatshrink looks neater than electrical tape, but as long as the joint is fully insulated, tape is fine.

just a quick question. the 4 pin connector has 2 black wires and 2 yellow with black stripe wires. the two yellow wires should be the same right as should the black ones?

I think this was already answered in your other thread, but I wouldn't mix them up. I bit of tape or a marker can help you keep things straight.
