Sleeving Question

[EmeraldKiwi]

So I de-pinned my 24 pin cable from my EVGA 750w G2 PSU (after making a pinout diagram of course and quadruple checking it) and I noticed that a couple wires are a bit thinner than the rest. I looked closer and on the wires, they say 300V, but in even finer print the thinner ones say 22AWG and the thicker ones say 18AWG. I did not account for this on my pinout diagram, so what I'm wondering is if it makes a difference where they go. If so, how am I going to find out where they are supposed to go?

 

EDIT:

Upon further investigation, I noticed a few cables are even LARGER than the regular ones. These few say 16 AWG. Still have no idea what to do though.

It does matter because different gauges have different resistances etc.

Care to elaborate?

AWG stands for American wire gauge. The gauge of the wire (conductor) give it properties (resistance etc.), basically how the conductor behaves when it leads electricity.

Would it be safe to take 18 AWG wires and use it in place of the 22 AWG wires? I'm just not willing to risk a house fire from wires with smaller amp "capacity"s.

I had this happen when I sleeved my AX 760 PSU those cables depending on the PSU are spliced together, so two cables were going into one connector on the 24 pin to supply extra power or amps to that pin. It's not a problem to replaced the 22AWG wires with 18AWG wires but it is a good idea to keep the 16AWG wires since those are the pins that use the highest current.

 

With that said I did a double wire method to clean things up on the motherboard end (this does place more current on the single wire going up to the 24 pin but is way within safe margins since 18AWG wire can take a max of 16Amps):

Okay I sort of get where you're coming from. I'm still a bit confused though. Say I have one 22 AWG wire that isn't a two pin to one pin thingy, like in the video. Just a normal wire that's 22 AWG. Would it be safe to replace that wire with an 18 AWG wire? Also, say my dual wire thingy has one 22 AWG wire and one 18 AWG wire. Those two wires went to two different spots on the PSU, but would it matter which way I placed them since they both lead to the same pin on the motherboard? Thanks for your help though. This 24 pin cable is the last cable to sleeve. Thank god.

Replacing the 22awg wire with 18awg is not a problem since you are going to a physically larger diameter wire wire. As for the double wire they don't matter which way you place them on the PSU end since both of those connections wire themselves together eventually but you must make sure however you are wiring those two wires to the same volts on the PSU end.

So according to this pinout diagram, 

http://www.overclock.net/content/type/61/id/2008572/width/500/height/1000/flags/LL

I would have to reference my diagram and this one to see where they go? What happens if the two wires go to two different voltages on the PSU end?

You definitely don't want them to cross two different voltages it will take the difference if those two volts on the 24 pin end, that can either kill the motherboard through too many volts or not have enough volts to supply that pin. I suggest using the diagram to make sure the two wires go to the correct connection of the same voltages and using a multimeter to check every single pin on the 24 pin end to double check it is correctly wired and of the proper voltages.

Okay. So check that they both go to the same voltage. What about the different guages of the two wires? Does the 22 or 18 AWG wires need to be placed into a certain spot?

Not really since the extra 22 AWG is just allowing for more amps to the 24 pin with the 18 AWG wire, and since you will be replacing it with 18 AWG it will make no difference.

Oh. Okay. What I meant by replacing the 22AWG wires were the single ones, not the dual ones. Good catch though. That said, now does it still not matter? If both wires of the dual wire are going to PSU pins that have the same voltages then it shouldn't matter right?

 

EDIT:

I used the provided pinout diagram and it looks like all the dual wire things go to the same voltage. The only question now is this:

Does it matter which pin the 22AWG wire or the 18AWG wire go to if both spots are the same voltage?

If your talking about the order of the pins as long as they are supplying the correct voltages on the motherboard end you can remap the wires on the PSU end and it's ok to replace the 22AWG wire. Also your correct about the double wires you just need to ensure both pins on the PSU end are the same voltages.

[EmeraldKiwi]

Okay, I went through each wire to check the guages, and there is only one single 16 AWG wire. Would anyone be able to tell me where it goes according to the pin out diagram provided in a previous post?
