As an alternative in THAT case would be to combine them into a single thick wire and at the plug end divide it into the smaller wires between the pins thus reducing overall wire clutter. The only issue then is the amount of current the connector pins can handle. Though, as an alternative one can do the math and simply decrease most of the common connected wires to a thicker gauge and remove the extra's altogether. In this case one wire cannot draw more than the others unless the lengths or wire conditions (poorer solder joint, looser crimp on the connecting pin, etc) are slightly different but it's negligible at best due to less than an ohm resistance difference. In turn it also reduces the effect of a voltage crop over the wires itself, again, due to less resistance as well. Essentially all it's doing is dividing the current between the wires to keep within ATX wire gauge specifications and avoid heat buildup while reducing wire resistance. That's actually the reason for the extra wires. I used a small push button switch to make this connection. If all the 5v wires are all the same, and also connected together on the same rail on the motherboard, how can one wire have a greater current draw than the others. In order to turn on the power supply we need to connect the green wire with the ground (one of the black wires). The voltage drop/current rating of the wire did cross my mind.
Or is this PSU only compatible with motherboards that have 24-pin sockets?
Or would it be preferable to swap this terminal (with the pink and red wire) with one of the other 5V terminals on the new 20-pin plug, so that the 5V rail is still regulated? If i replaced the wires to exaclty the same positions, then this pink wire (which would now be in the 4-pin plug) would wind up not being used. I read, in another thread, that this is a sensor wire. I had unclipped (with the eye of a needle) and removed all of the pins from another 20+4 pin plug, and was going to transfer the bestec wires over into this empty plug, untill i noticed a pink wire doubled up with a red wire, on pin 23.

The plug wont fit into the socket because there are components in the way. This bestec has a 24-pin plug that can not be seperated into a 20+4 pin. It's going onto a motherboard with only a 20-pin power socket. Decided to buy a half decent (well, at least, not bottom of the barrell) PSU.
