Brownout possible cause, bought new PC and it happened again

[Polarisandneptune276]

I was having major stuttering issues on my PC, I tried 1000's of hours to try and get it right, but it wouldn't work. I chalked it up to being that my at has power issues and had a few mini brownouts (although I have been told that my PSU Evga Gold G2 defends against short voltage drops).

 

I purchased an entire new system mobo ram and cpu skylake, and it was fine for two days.

 

Last night I had some of those power issues in my flat, lights flickering. I went to play and lo and behold the stuttering is back again.

 

UPS are simply too expensive where I live.

Get a UPS.

I have been told by experienced users on general that they aren't necessary, they also cost 100+

By whom? We have no idea the scale or actual effect of these brownouts. Yes, theoretically if we're talking a few microseconds of power loss, some PSUs will be able to handle that. However, without actually measuring what is occurring during these brownouts, it's pretty hard to recommend anything but a UPS, or trading in your desktop for a laptop. Changing PSUs is only going to buy you a few miliseconds either way, and if this is a consistent issue in your building to the point where the lights flicker regularly, then it's only a matter of time until it then crosses that threshold, and you're no further along. A UPS would provide you protection for MINUTES. Tens of thousands of times longer than any PSU swap.

 

You don't need to get a particularly built up unit for this, as you aren't planning on running it exclusively off the battery. Just something that'll give you even 10 minutes would prevent this.

A couple of long time posters told me that a decent psu will have just as much protection from undervolting, while never actually losing power which I don't. Light flickering suggest fluctuations in voltage that PSU's can handle apparently. There doesn't seem to be a Ms limit on when damage occurs.But I do agree Sith what you are saying about it giving me more time.

 

UPS's at 500w are really expensive, I just can afford them right now. 

 

If damage has happened wouldn't this show up in benchmarks, which it isn't.

Seems like maybe faulty wiring in your place?

I was reading this thread about how they aren't really necessary.

Your desktop is only probably causing a few milliseconds of light loss, it's too short to notice. Is your desktop pulling enough voltage to make it like a scary movie where they're constantly flickering?

Ups is always effective and worth every penny. 

You don't have to go expensive for brown outs.
