Installing MoBo
Hi All
I'm trying to build my first home-build computer.(Asus A7N8X-E) And now I have a question about how I do installing my MoBo in the case.I have fit those copper things to keep the distants between the case and the MoBo.On the MoBo side I have to fit these little ring for the electrical insulation (or is this isolation!!!) Whatever, my question is::do I fit those rings on both sides, or just on the top side of the MoBo. Thx in advance françois |

The distance is so that the underside of the mainboard does not contact the metal case. On the MoBo side I have to fit these little ring for the electrical insulation (or is this isolation!!!) Whatever, my question is::do I fit those rings on both sides, or just on the top side of the MoBo. Maybe neither. Did you get those rings from some shop? Modern mainboard's are designed to be grounded at those points (I'm not saying it's absolutely necessary). http://usa.asus.com/products/mb/sock...7n8x-e-d_l.jpg In the picture, you can see silver colored electrically conductive circles around the mainboard mounting holes. Those are ground points, they are connected directly to device ground pins on the mainboard. Power supply and mainboard ground are connected to the case. There's no reason to insulate those points. Of course you might want to avoid overtightening the screws or using screws which have very big heads. |

Washers: Generally made of plastic or paper, these go under the screws
to keep the screw head away from the circuitry on the top surface of the motherboard. These are now sometimes being omitted in new system cases because they are less necessary now than they once were (since motherboards today now tend to keep the circuitry farther away from the screwholes than they once did). http://www.pcguide.com/ref/case/partsHardware-c.html wrote in message ...

Good choice. And now I have a question about how I do installing my MoBo in the case.I have fit those copper things to keep the distants between the case and the MoBo. Be very careful that you don't put a brass spacer somewhere behind the board, then forget it's there when you fit the motherboard into the case. It could short out the board if it makes contact with the circuits on the back. Just keep track of them and make sure you have a screw hole on the motherboard for each spacer you put onto the case. On the MoBo side I have to fit these little ring for the electrical insulation (or is this isolation!!!) Whatever, my question is::do I fit those rings on both sides, or just on the top side of the MoBo. Those little paper rings are just extras. You don't need them. The board is designed to be insulated from the brass spacers at the screw holes. |

On the MoBo side I have to fit these little ring for the electrical insulation (or is this isolation!!!) do I fit those rings on both sides, or just on the top side of the MoBo. The copper things are actually brass and called "standoffs." When in doubt, install those rings (fiber washers) on both sides of each hole because if you leave out a needed washer, the motherboard will short to ground and possibly be damaged. On the other hand if you install unneeded washers you'll simply waste some time and washers and have marginally worse immunity to electrical noise. Nobody should make a blanket recommendation about insulator washers and all motherboards, and each board must be inspected individually. If a side of a mounting hole is surrounded by a copper donut (usually has 6 tiny holes around it, may be coated with solder) or is completely clear of any copper (neither standoff nor screw can possibly touch copper traces), then it doesn't need an insulator washer. Motherboards made in the past 5 years rarely need insulators but I've seen exceptions as new as 12 months old. |
