Hi there everyone. I'm not asking for technical support, just want some opinions. Today I left my two month old home built computer on sleep, came back about an hour later and found it dead. No power, nothing. I tested the PSU in a variety of ways and it just seems to be completely dead. I even used another power supply and the system powered on.
This leads me to believe that the power supply failed. It is a Seasonic M12II-750 BRONZE ATX 750 Power Supply that i got from Amazon about 2 months ago. I thought this was a relatively highly regarded PSU. The strange thing is that there were no signs of trouble whatsoever. No issues at all. I have not installed any new hardware or software. No strange smell, no smoke, no dust in the unit, no boot/power-on issues. Just randomly died. This seems very uncommon from what I can tell.
I am running SLI 670s and an i5-3750 and I thought that PSU would be more than enough for my system.
I hope that it didn't damage the MOBO in any way. Kind of lame that the product would crap out like that so soon.
It is under warranty so I am going to RMA for another unit I suppose.
everything is mass produced. nothing lasts forever. that is a solid supply, you just got unlucky.
or your house has dirty power.
are you using a ups?
It's possible my house has "dirty power"--it's an appartment building that is ancient and built in the 40s. I don't exactly know what dirty power is. I also don't use a UPS. What exactly is that? I just have it plugged into a regular surge protector. I have multiple computers running in the house but that one sucks the most power by far.
You might have just gotten unlucky and received a bad unit.
Or there was a power spike, brownout (when the wall voltage dips significantly) or some other freak event that killed it.
Extreme heat may have also done it, but I doubt it.
Dirty Power is a term for when voltages aren't stable and can vary from what they are supposed to be.
Depends on where you live what the wall voltages are, but if you monitor it and it is significantly changing up and down from what its supposed to be, you are getting "dirty power".
Dirty power wont outright kill a component (unless it spikes ridiculously high), but will wear out the component a lot faster.
Thats why 80+ Standard Certification states that (this is internal power, not wall power) there can only be a 5% variance in voltage. So your 12v rail must stay within 11.7 and 12.3 Volts if it wants to be Certified.
