Fluctuating home voltage could it fry my computer ? A/C compressor kicks in = lights dim for a split second !

post #1 of 18
Thread Starter 
so it was ok until i installed an A/C the other day, the problem is whenever the A/C compressor kicks in the lights all over my house dims for a split second, could this fry my computer somehow ?

i heard that modern power supplies do have measures to counter this issue, this happens every 5 minutes maybe every time the compressor of the A/C kicks in to keep the room @ 25c

it's too hot here and getting an A/C made quit a difference can't give it up.....

Yes voltage drop does and can hurt a computer. Some modern PSU do lvl the voltage out a bit. Ive had my lights go out just long enough that you know they did. I checked my folding rig,soon to be retired, and it was still running. SO I imagine that they have some extra capacity to handle bumps. If your worried get a USP big enough for you rig. They generally are active and DO level the voltage coming into your rig up and down.

my psu is the seasonic x series 1250w does it have the voltage leveling function ?

i also got another computer running of a Seasonic M12II Bronze 850w does it have the leveling function as well ?

any solution to counter this issue ?

You shouldn't have a problem. Any decently made PSU has voltage regulation built in to compensate for fluctuations in the grid. A split second voltage drop isn't going to hurt your system. But as others have said, if you're worried about it, get a UPS.

money is kind of tight now to go out and get a UPS, you had this happen to you in the past like when ever a high load machine kicked in your house the lights would dim for a split second ? but it didn't hurt your folding machine ? for how long you had that folding machine running ?
