PSU wires

[DuckDodgers]

I just upgraded to an NF7-S unlike my older board it seems the are 2 power source wires, one has 20 wires and the other has 4. What do I do with the 4 wire? Does it need to be plugged in?

no you dont need it if you dont have it

page 3-10

General designed ATX power supply do not have ATX12V1 connector so you don't need to connect anything to the ATX12V1 connector

haha, thats too bad i could use one with everything i have going on this week ;)

its just to help out with the 12v on the motherboard. i thought i had heard it was mainly there because p4s used the 12v a lot, and amd boards just use it as a back up? my gigabyte p4 board worked without it, but it behaved kinda funny. random reboots and such. that is until i saw it was unplugged.

on that same page of the manual, it says:

It can provide for power supply designed for Pentium 4 processors... ...It's a newly designed ATX12V1 +12VDC

im really not 100% sure, im just piecing together bits i've heard

It is a 12v line tap for power hungry cpus. As said before, the Willy core (origonal P4) was a power hungry chip, so this connector was made to accomidate it.

Now it is used on lots of boards/cpus for other power hungry chips.

Thanks for the replies..... guess I'll just hook it up for the fun of it.
Better to plug it in than to just let it dangle... :)

Plug it in. it's surprising the manual says that for many AMD boards with the 4pin
header won't boot without it.
