Thread: Dont understand how to connect power wire to pc

Perhaps this will help:

ok so the power wire connect to the battery and i run it to my computer which has the built in opus PSU...i connect that power wire which is 12 AWG to the either 1) 6 pin connector which has 2 yellow, 2 black, 1 red, and 1 blue cord, or 2) 3 pin connector with 1 yellow, 1 black and 1 red...which one is it?



also what does the red circular band do???

I would REALLY read up on how to build a PC before attempting something like this

*/this is more of a note for ANYONE reading this thread before starting their PC build - as this user has apparently already gotten in over his head/*

OP: can you link to the precise unit you bought from the store?

Have you looked at the manual for the Opus 120w?

I think i am figuring it out...i was kind of expecting something like an amp where you insert the wire into a slot and such...i didnt expect to just connect the wires together, but ill solder them together and see how things go...which one of those 2 do i use for the main power...the one with 6 right? and the other one i can use to power my xenarc 7" touch screen right? thanks guys

on the directions it says both yellow are power and both black are ground...do i run 2 power and 2 ground...maybe so i can power the monitor off the other adapter (the one with 3 wires?)

This is the part i struggle with...its the computer part that i am good with, so please bear with me...thanks

Did you ever consider maybe contacting Opus Solutions for an explanation?

I can see how the 6 plugs in, but I cannot see how the 3 plugs in....does the 3 plug into the ATX power connector? (the long, many wired plug)

According to the manual, I would be confused too....it does show that there are 2 power and ground, which would lead me to think like you, that there are two power and ground....which doesn't make sense....

According to the power diagram in the manual, and looking at the pic of the board, I would assume that yes, there are two power wires, and two grounds. I am thinking, though I may be wrong, that if you use one yellow and black for battery/ground, you may be able to use the other to power an external source. That doesn't seem logical if the 3 plug plugs into the ATX connector....that would be the purpose of the 3 plug, in that case, a +, switched, and ground for powering external stuff.

Does the 3 plug also plug into the same plug as the 6? Maybe the 6 is used for higher power applications?

The coiled red cable looks like a SATA hard drive connector. Don't worry about it until you buy an SATA hard drive. It comes with the MB, not a part of the power connector.

It would sure be nice if some people stepped off their high horse and provided a 3 seconed response that could help you AND others...

If I were you, I would do this: 1 Yellow to batt. 1 ground, 1 red to switched, blue to amp or whatever you would like to turn on....it's the same as the blue wire off your deck used for an amp - remote turn on.

Then, I would tape off the other black and yellow and see what happens...test it to make sure you are getting what you need. If the yellow provides power AFTER the unit turns on, I would use it for a external device.

Glad I didn't buy an opus now....those directions are as useful as a heart attack. Opus should Save the paper....just say "figure it out yourself! We made it, but we don't know how it works!"

Good luck!

thanks for your thoughts...i however read somewhere else on here, the best write up i have seen... took me forever to find it though...any one is interested, here it is

FAQ: How to Wire an OPUS PSU

i guess you connect both yellow to one power wire, and both grounds to the grounding wire?? i dunno why they did it that way...maybe they should have said something about that cuz that is not very "normal" i would have to say
