Which Component Is Failing?

[ddswh1pk0s]

Hey guys I am having an issue at the moment with random shutdowns. More info here: http://linustechtips.com/main/topic/386983-follow-up-computer-powers-off-randomly/

 

However, I am not sure which component is failing so I know which one to return. If I run a game, then the shutdowns happen, but this is because the PSU and GPU are under heavy load. If my PC is just idling, then the shutdowns don't happen.

 

Since I've taken my graphics card out no more shutdowns have occurred because my PSU doesn't have to supply power to my GPU. Or maybe my GPU is causing the shutdowns and now that it's gone my PC will be fine?

 

I'm not sure which one is failing, is there anyway I can stress test my PSU without the GPU in it to see if it fails?

 

My GPU isn't producing any artifacts or any other graphical issues before or after the shutdowns occur, so that leads me to believe that the GPU may not be the problem.

 

Thanks in advance

I would say the PSU is being taxed a little too much, since you also have two HDDs, as well as a slightly power hungry CPU.

 

All in all, I would say a 650 or 750 watt PSU may be more reliable. Also, good job on the eVGA in your signature, nice to see people being proper.

Situations like this are why I would advocate keeping spare hardware on hand instead of immediately selling them. Of course, if that is simply not feasible then there is nothing that can be done.

 

Do you have an spare hardware whatsoever? If I were faced with this situation, the power supply would be the first thing I swap.

The power supply is most likely the issue if temps are in check.

Thanks for your answers guys I'm going to take my PSU back on the weekend since it's still covered by warranty.

If you're O/Cing, that 550W is way too weak. It's a good psu, just over its head. I would recommend either 750W or 850W and make sure it's a good one. Gold, minimum. EVGA G2 or GS is the way I'd go.

I'm not OCing anything. I've had my system for over 6 months, I think I would know if 550W was not enough by now.  Also, when I was planning my build I put a 750W PSU and then people were having a fit that 750W was way too overkill unless I was doing SLI

 

rough over exaggerated numbers:

CPU: 150W

GPU: 200W

HDD1: 10W

HDD2 10W

Fan1: 20W

Fan2 20W

 

Total = 410W, and those numbers were very exaggerated.
