computer shut off during a benchmark

I was running the Hard Reset game benchmark and my pc just completely shut off. I have the alarm muted on my UPS but the lcd on it was active which only happens if manually click on or there is a power problem. there was no issue in the house itself as for a power goes so maybe the power supply had an issue and caused the pc to turn off? or is possible the UPS caused the problem? anyway now I am paranoid as hell. :(
 
There could be a lot of things at work here. I've seen systems shut down due to thermal events with the CPU or motherboard. If the UPS is being taxed past it's rated output then it may shut down completely. Most 1500VA UPS's actually only put out 900watts of power. I had a machine draw 1100 watts under full load which would cause an issue exactly as you described.
 
so you think the UPS just took a crap for a second and some how caused the issue? anything non power related would not have had the UPS alarm come on.

I have ran a few intense benchmark loops since then and no issues but again I am now paranoid as hell.
 
It's possible it was the UPS, or it may have been a random crash. Unless you have persistent problems, I wouldn't worry about it.

it was not a crash. the UPS alarm and lcd would not have popped on from just a regular crash. it was 100% power related in some way.

if the UPS screwed up enough to force the power supply to shut off then that is certainly something I should be worried about. if it was not the UPS then it had to be the power supply itself so neither scenario sounds good to me. :(
 
I just figured out the problem thanks to the xbit review of the 620 watt version of my psu. http://www.xbitlabs.com/articles/cases/display/psu-600w-850w_5.html#sect0

UPS Compatibility

Like its Seasonic progenitors, the Antec Neo ECO 620C refused to be compatible with my UPS. They were stable at loads up to 370 watts when powered by the mains but couldn’t work even at 280 watts on the UPS batteries.


what must have happened that day was a slight power loss or self test on the UPS that made it use the batteries for a split second. that of course forced my pc off since it was using 325 watts. that makes since because xbit says the other similar Seasonic built psus will not work on the batteries at over 280 watts.

so just to make sure, I fired up that same benchmark and then pulled the plug from the wall. sure enough the pc turned right off. needless to say I am extremely pissed off since I have no protection if the power goes off under load.

the problem is who do I need to be pissed at? Seasonic for making the psu? Antec since it has their name on it? or Cyberpower since their UPS is useless when my pc is under load?
 
You should be mad at Cyberpower, but also partially at yourself by not buying the proper UPS for your system. Older PSUs with passive or no PFC would work with pretty much any UPS, but PSUs with active PFC are picky about the UPS they will work well with.

It's a relatively unknown fact about these compatibility issues, so don't feel too bad about not knowing about it.

how is the UPS I bought not a proper one for my system? did you even see the link to the UPS I have before blaming me?
 
Oh, well, in that case it's probably Seasonic. Or just the components Seasonic chooses to use.

Odd though that they didn't rectify the problem. A high quality company like Seasonic usually recognizes and responds immediately to complaints.

yeah they would be the last company that I would think could have an issue like this. I guess there is nothing I can do but it sucks that I bought a $150 UPS that is of no use under load.
