Need help on unstable power.

Hello guys!

I couldn't find a proper sections in the forum to post this so here goes....

Since I bought my motherboard about a year ago from now, I have been experiencing very very rare instability issues in-game and under light-load. It was until recently that someone pointed out it may be an unstable power problem. And I believe he was right on the money. Some indications of this include: sound distortion from turning off the table fan (that is connected to the same multi-outlet of my PC), or sound distortions when someone hits the light switch near my PC.

I currently live in a garage converted into a room with its own private bathroom. So it is very likely poor wiring as a result. Any ideas on how to get around this issue? Maybe using a high quality extension cord to try other outlets? Buying a backup PSU? I'm willing to try any helpful suggestions.

What PSU do you currently have in the rig?

I'm thinking possible bad ground. Less likely to be insufficient voltage.

This would help determine if your polarity and grounding are correct.

This for more extensive testing (for brownout issues)

If you determine the issue to be either of those the landlord needs to fix it asap.

My landlord is very stubborn. Took weeks for him to finally fix my plumbing. Frankly, I don't want to move because I got a really good deal on the rent, because he never leased a room before. And it would be impossible to convince him to fix it if there is no visible issue. Everything works fine, but my PC experiences very very rare instability.

I found an extensive thread about UPS in a PC forum. It mentions that some can filter noise in the main, and correct brownouts or surges. I don't think I have a choice, but to buy a UPS in my situation.

If it's voltage irregularities I'd get a ups that always converts ac to dc then back to ac. It's less efficient, but if you have frequent brownouts your ups may want to run on battery all the time which could become problematic.

Get the simple tester first. If you have a grounding problem get a power strip with auxiliary ground and drive a grounding rod into the earth, then clamp a single piece of #10 wire to the rod and secure the other end to the power strip grounding point. That will correct the issue, but check it with the tool first to be sure.

Is it ok if I buy this brand? https://www.amazon.com/Sperry-Instru...=outlet+tester Or should I go for the klein brand like you said.


Edit: I think I'm just going to buy this https://www.amazon.com/Klein-Tools-6...=outlet+tester I think the klein brand would be safer and accurate, right?

No matter what, always run your PC behind a UPS. Preferably one with Pure Sine Wave protection.

Here's an example, I picked one with a high VA load, which should give you a good run time and life as it will not be stressed if you only have a PC behind it.

I have an APC 1500VA unit (865W), it's not pure sine wave and is quite a bit cheaper. Been going strong for quite a few years now and really helps with stability in general, not to mention covering me when I have a brownout. I also have my cable modem and VOIP as well as monitors (of course) on it. Handles everything nicely.

Though expensive, just remember that these are a long term investment, and will save your computer hardware from early, untimely deaths. Just as a good quality PSU is necessary for long term PC health, a UPS is just as much a necessity.
