Connected a PC to an outlet lacking a ground connection...
Hi,
I want to start by saying that this post might not be in the right place, but I found a more suitable section on the site. Also, I’m aware there aren’t many good places to discuss computer issues properly.
Not long ago, I assembled a $500 PC using new parts (a list is available if needed). Recently, I moved and, due to carelessness, forgot that none of the outlets in my apartment have a ground connection. I became very upset when I tested each outlet with a neon tester—none had the necessary ground wire.
Rewiring some of these outlets would cost at least $1000, which is more than my PC itself.
I haven’t connected my computer yet because of fear. I know a surge protector is essential, but what else could happen without a ground? I’m not very familiar with the subject and haven’t found clear information online. My main concern isn’t just surges, but possible static buildup that a PC might discharge.
I’m hoping this community can help me understand what’s going on.
Thanks much,
Ryan
You'll need a foundation, and it looks like your building owner should cover the cost.

$1000 allocated for grounding connection. Connect a wire to copper pipe and complete the grounding.
I need to wire a ground for $1000? That’s a lot of money. Connecting a wire to copper pipe and grounding it seems straightforward, but if there’s a surge, I can’t promise safety. As an electrical engineer, I’d advise the building owner to redesign the system. If they can’t, they should consider tearing it down. Honestly, I shouldn’t invest $5000 in electronics when the power is as outdated as WWII.
Risk 5000$ for electronics when the electricity is as old as WWII. Actually it's $500, not $5000. I’ll have to be more confident about getting proper wiring installed. That looks like the best solution. On the back wall of the apartment there’s a grounded outlet, so I know the box has a ground, which is encouraging. Of course, the only accessible one had to be missing... I appreciate the advice.
If I'm not wrong, even with two-prong outlets, having one prong positive and one negative suggests the negative acts as a ground. Be aware, though, and think about getting a UPS, or battery backup, to stabilize voltage fluctuations for your equipment.
If the building is old enough to lack proper grounding, it's possible it never had any wiring connected to the outlets and might even use outdated aluminum wire that would need a full rewiring. There’s no safe method to replicate grounding. I support the idea of using a battery backup as your top choice for surge protection—opt for one that converts AC to DC to some extent, though a power surge could still cause serious damage like a lead-acid battery exploding. Check with your local town or city about wiring regulations in rental properties; many require landlords to handle upgrades to meet codes.
110 works in this way, one of the plugs is hot, 110 volts.
The other is referred to as the common or ground, and it is connected at the power company.
The third serves as an extra safety feature in case of incorrect wiring; it is the round ground plug, which is physically grounded at your house. It essentially means attaching a third wire, connecting it to a copper pipe, and inserting it into the ground.
You can purchase an adapter that lets you link a ground wire to the screw in the center of the face plate. Of course, this won’t help if the box itself isn’t grounded. Still, it allows you to plug it in. Even though the electricity in your building doesn’t meet current codes, I recommend using a good surge protector on the plug and don’t stress too much about it.
An UPS will check if it’s connected to a grounded outlet, and it will grumble if it can’t find one. Back in the day, two wires were standard; however, it’s only risky if the gear linked to them malfunctions improperly.
If the building won’t resolve the issue, you might attempt a makeshift fix yourself.
I recommend purchasing a 3-prong outlet and some green insulated ground wire. Connect one end to the outlet’s ground and the other to a cold water pipe or metal radiator.
Use your tester to verify the setup.
