is it safe to make psu cables longer?

post #1 of 5
Thread Starter 
just wondering if it would be safe to lengthen the cables (solder em then heatshrink the join) as my next case will be alot bigger then my current and might need to make some adjustmence, also what size wire would be best to get if it's safe to do so?

As long as they're soldered and correct there should be no problem.Just make sure they are soldered well. You can twist them but like every wiring job,solder is best.

No problem extending them. I do it all the time.
The soldering and heatshrink method will give you the best results certainly.
As far as wire size, you should try to use the same size wire as the one you are extending. Although I have used different size wire sometimes but you have to be careful what kind of load will be on the wire before you go changing wire size.
Most wire in modern power supplies "seems to be" 18 awg though I see a lot of molex extension cables that are 20 awg and sometimes (depending on the PSU and the rating of it) you will see some 16 awg wire on the main lines (24 pin MB one, 8 pin cpu one, and 6 or 8 pin gpu ones).

There is no real danger extending them as long as you are not talking adding several feet to a wire. A foot or two will not make much of a difference to things as long as your soldering is good.

Have at it and good luck.

I had Performance PC's make me up extensions (with the coresponsing male/female sockets/connectors). It was not the cheap way to go (I did an remote P/S located rig and a 5ft 24-pin extension was 75.00). One of the reasons I did this was to maintain P/S warranty. You will be denied warranty with just about any mod. to the cables (Corsair made an exception for me with the heatshrink sleeve on one unit, but it was close)

yea i have done alot of soldering before just not on power supplies, was gonna twist the wire together and solder it then with the heatshrink will help with any short circuit that may occur
