Are all ground wires the same?
a ground and a neutral are both wires. unless they’re tied together with other circuits, and not a ‘home run’ back to the panel, there is no difference between the two where they both end up on the same bus bar in the box.
Why is there an extra ground wire?
The purpose of a ground wire is to give excess electrical charges a safe place to go. A ground wire helps those positive charges get to the ground in a safe, direct and controlled way, where they can be discharged without the risk of electrical shock or fire.
Can ground wires be tied together?
You should tie all the ground wires together, albeit in reality it really doesn’t matter as long as none are disconnected.
Is black wire hot?
Black wires are “hot” wires, which means they carry a live current from your electrical panel to the destination. They feed electricity to electrical outlets, switches and appliances from the home’s main power supply.
What kind of power supply do I need for an ATX PSU?
If you cannot tell which wires are sense in your original harness, you will need to connect together ALL +5V wires, connect together ALL +3.3V wires, connect together ALL +12V wires, and connect together all ground wires. Edit: I just checked the ATX specification and it appears that there is probably only a sense line on the +3.3V.
Should the PSU be physically grounded to the case via?
If you really want to encourage this persons OCD, then what needs to be done is to connect the computer case to 4 gauge copper wire, which you would then run to an eight foot copper stake driven in to the earth under the house. Only then would proper grounding be assured!! :haha:
How many ground wires are in a molex power supply?
All the other plugs coming out of the power supply—called Molex connectors—are for drives, and they provide +12V (yellow) and +5V (red) power, as well as two ground wires (black). Power supplies are sold using two main specifications: the form factor and the wattage. Wattage is volts multiplied by amps.
How are electronics grounded to a computer case?
First, most of the electronics you would put on a computer, like motherboard, are grounded to the case through the screws.
