PSU or electrical?

post #1 of 15
Thread Starter 
so whenever my cards reach higher loads my little lamp in my room starts to flicker..i already know my psu isnt enough to push my 2 titans on the skynet's bios with a 3930k but the cards for now are on stock clocks..and on 100% power target and yet when the gpu loads reach around 60-70 the light starts to flicker and anymore than that the psu shuts off..my build also WC using 2 pumps w 11 fans and the aquero 5 fan controller...is it the psu or is it electrical?.....

If your lamp is flickering, it sounds like electrical. Is the lamp on the same circuit as your PC? Might be a faulty breaker... that spazzes out a little when a load is put on it. Do the lights flicker when your AC, or refrigerator kicks on? If so, it might be more than just a single breaker.

How much do you have plugged into that line? Depending on where you are, code will determine how many devices you are supposed to be able to hook up on each breaker (usually around 12 or so for a 15 amp breaker)... actually based on load current... not supposed to exceed 80% of the breakers rating. Do you know if the amperage of the breaker you are on? If it is overloaded... it can cause that brownout effect at times.

You might try resetting the breaker (make sure all connected devices are off first, of course). Sometime they develop a weak connection, and a reset will correct it. If not, you may need change out the breaker (get a electrician if you are not comfortable with it)


If it was PSU.. the symptoms would be limited to your PC... unless you were getting a serious short, and you would notice that... wink.gif

If you can reduce the load on that one circuit... it will help. Keep in mind that each run, will have multiple outlets on it. So it may not be possible to find an outlet that isn't on the run if it is a small room. If the breaker is going bad, it will just continue to get worse.

At least try resetting the breaker. That is easy.

Cool! Keep in mind, I am not an electrician... and am making assumptions as to what is going on, based on what you said. I do have quite a bit of experience with electrical (have wired several houses, top to bottom... had a buddy who was an electrician, I used to help him for fun and beer. Almost got my journeymans license under him, lol!)

good enough for me lol

What breakers do you have? I'd get an electrician to get it checked out if you aren't drawing > 80% of the rated amperage on it.

It does not sound like PSU problem. When my air conditioner kicks it in makes my lights flicker a bit. You should try turning some stuff off in your house while using your pc. You got a grate PC, so you probably have really good speakers with a high powered amp? Are you speakers and computer pluged into the same outlet? If that does not help you can try down clocking the cards.
Thats crazy, I have never heard of a PC so powerful that it shuts down a house.

you ABSOLUTELY need a UPS for your system. at the very least a power conditioner. your house wiring is going to kill your system some day if you don't do something biggrin.gif
