I know that the answer is yes, I should, but outlets near the setup are not grounded (even though they look like they are) and I don’t want to have wires running though my living room.
The real question is what are potential problems ? Occasional system reboots? Permanent damage to PSU? Permanent damage to other components?
It will not affect system stability, but… Surge protectors do not work at all without a ground wire to drop excess voltage to. Any kind of line voltage disturbance could kill every device.
Additionally, without any ground wire to pull the housings of devices to ground, the potential for a short to energize the case and then electrocute you is also high.
additionally additionally, if you have grounded outlets that don’t actually have a ground connection running to them, that means either the wiring system is broken or it was “updated” by an unlicensed hack job who has undoubtedly made numerous more dangerous decisions elsewhere in the circuit.
If your house is entirely ungrounded you really should have an electrician come update it ASAP. Outlet grounds have been mandatory since 1971. The chances are high that wiring predating that code is still using old cloth-wrapped wire insulation or even knob&tube, both of which are huge fire risks as the insulation is decayed badly by now. It’s expensive to have all new wire pulled but it is necessary.
Can confirm. Neighbors house had an attic fire with knob & tube wiring.
… Just like the stuff still in my place today. Eek! Landlord won’t upgrade unless there is a problem. In my house, the breakers are all 20amp and that’s a lot to run on, best guess, 70 year old wires.
Oh, and do not assume anything is wired as expected. Test after. I’ve found a couple plugs “upgraded” to 3-prong by jumping the load and ground together. That made for a fun firework show when my metal fan touched something metal. Even the landlord was impressed by that stupidity.
A cheaper solution is to take a copper wire and connect the ground screw of the socket to a water pipe. It does the job and is better than nothing.
Note to anyone heeding this advice: it has to be a metal water pipe, no plastic.
Yeah it’s pricey, very pricey, but the risks are just too high for a home not to be properly grounded anymore. Homeowners have had 50 years to do it, it’s time to get it done.
Heh. House I rented was built before ubiquitous electricity. At some point, someone slapped a fuse box on the outside of the back wall and drilled a bunch of 1" holes in said wall to pass wiring. House was built on piers, so they just dragged wires around to places where they wanted outlets, which were mostly planted in the floor. Not a ground wire on site. I have no idea how they got away with renting that out, but it’s not like I called code enforcement, either.
My house was built in 1939. Initial installation of ecectric cables consisted of a wire in a sleeve filled over with concrete. That was all replaced with proper tubing and isolation, but these few outlets do not have ground.
Surge suppressors do not drop extra voltage to ground. They selectively short out surges between whatever two conductors have a high potential between them.
No ground conductor means there cannot be a high potential between it and anything else!
I know that the answer is yes
I mean, there you go, and all of the above. I’d add in a pretty large fire risk too. I hear my battery backups kick in regularly, and we’re talking about enough power to equal a large appliance (at least in my case). It’s 100% worth it to move them to a grounded outlet.
Without a ground there is nowhere for a surge to go, permanent damage is much more likely. Surge protectors or a UPS will not protect against surges at all without a ground.
There’s also no ground so the chassis may have enough voltage on it to cause a shock if you touch it. This could also damage components as they are not grounded and touching things can introduce high voltage from static electricity which will have nowhere to go.
Additionally if you have ethernet connected to it the system may end up grounding itself through the ethernet cable, if the device at the other side does have a ground, which could cause issues.
So it basically just means you have a much higher chance of damaging the parts, or injuring someone touching things.
Electric shock to you? Get an electrician to check it and sign it off?
Other question for anyone listening here: How can we check if an outlet is correctly grounded ? I live in a faily new appartment with good outlets, but maybe I should make sure they are OK ?
$10-15 will get you an outlet tester at just about every home improvement store. You plug it in and the three big LEDs light up and you compare it with the sticker on the device. Get one with a GFCI tester built in, when you press the button it will short to ground and if your receptacle has GFCI protection or is on a GFCI protected circuit should trip the GFCI protection.
Grab something like this: https://www.amazon.ca/Gardner-Bender-GRT-3500-Standard-Outlet/dp/B000NBDTQI
The most important risk you face is if somehow mains voltage ends up contacting somewhere you get electrocuted and die.
There are 2 purposes of an earth ground: First it can be used as a reference for certain signals, such as microphones. Second, it can be used to protect against turning yourself into a sparker.
There is a clear separation between mains voltage and system voltages so it’s typically not going to be a problem, but if a little wire ends up contacting the power supply case it can become energized and things start to get really bad.
Most of the electrical code where I live focuses on grounding as “Bonding”, which is purely safety related for giving dangerous voltages a safe place to go.
Do you have money to replace everything plugged into those outlets, and sufficient home insurance that also ignores such things? Then, no, I guess.
Just take an hour and make a ground yourself. It doesn’t take a lot of specialized knowledge to do so.
Edit to say, I’m pretty sure any surge protector worth itself has a ground output on it already. Just run a wire from it into the literal ground if possible, or over to a place in your home that is properly grounded. You’re just trying to give something like a lightning strike a path of least resistance to discharge into. Any metal conduit in your home SHOULD be grounded, so that’s an easy option.

Install GFCI plugs. [1]

Buy a small, appropriately sized UPS.

Profit?
Disclaimer: Am not actually electrician. Just know this about GFCI from electrician friends and pointing to a decent explainer.
GFCI plugs can be installed without a ground wire. https://diy.stackexchange.com/questions/225370/i-live-in-an-older-home-without-ground-wiring-is-it-safe-to-install-3-prong-gfc ↩︎
You are correct that this is technically in code and would protect against shock hazards in a neutral error situation but you also get the opportunity for the outlet to pop during the day when nobody is home and the battery to die.
We had a situation in our old house where someone who was technically correct but didn’t think it through had a gfci outlet upstream of the refrigerator outlet. Thankfully it popped while someone was home and we got everything corrected before we lost everything in the fridge.
For sure, a fridge is a really bad one to be using on an actual ungrounded GFCI, exactly for the reason of risk of expired food.
I like my homeserver but if something trips and its offline for a while it’s not gonna ruin my day.
The battery can be recharged eventually unless it’s already be discharged many times or it’s left alone and dead long enough to kill any ability to recharge it.
