what's this about grounding a power supply?

**saikano** · 07-15-2004, 01:08 AM

ok, i get to ask stupid questions like this because i'm a girl.

now. here. goes.

i was under the impression that if i got my power supply, i could just stick it someplace out of the way, as long as it reaches the mobo.

now, after reading some posts about improperly grounded psu's [or so i understood]...what is the right way? those threads didn't help.

and do i have the concepts right? that a psu must be grounded instead of placed anywhere?

i'd like to know, so i can include this in my planning stage

Are you using a DC/DC PSU like an Opus or are you using an inverter with an AC/DC PSU?

You're a girl...HA! that explains a lot of your questions. Most people doing this I've found are dudes and I assumed you were. I was like has this guy been living in a closet. Don't know the answer to this one though although grounding usually means connecting a wire to the metal of whatever your trying to ground, in this case psu, to the chasis or metal body frame of the car. You have a small grasp of it but grounding is totally different from placement. You can place an object anywhere but in order to ground that object you must do what I just posted two sentences previous to this one. If you've ever looked under your hood at your battery you have a + and you have a -. The - is the ground. If you follow that wire you'll see that it connects to something metal in the engine bay area. That's what it means to ground in an automobile environment...you have a wire connected to the object(battery) and the wire goes to a metal part of the car body frame.

sorry defiler - i'm planning on running an opus 90W psu...

**nl4jy** · 07-15-2004, 03:53 PM

Then grounding is the (-) on the battery.

It's very simple and there's a PDF on how to wire the Opus...[too lazy to search...gonna have to do that yourself]

Basically 3 colors from opus... Red is for (+) on battery, Black is for (-) on battery and Yellow is for the iginition/ACC wire somewhere under the steering wheel...You can also use the fusebox if you don't want to stripe any wires.

Didn't mean it in a negative way. I'm always willing to help guy or girl.
