PC shuts down randomly

[Runar Sandstaa]

Hi. I am having a problem with my computer where it randomly shuts down (like when you hold down the powerbutton for too long and it makes a "click" when it shuts down). I do not get any warning and the tempereatures look fine. the computer are also usually under hevy load when this problem accures.

 

Hope someone can help me.

Without me looking any further - on a glance it looks like the PSU can't supply enough power and cuts out. But I'll take a look and edit this if I find something else out.

 

Edit: The watt consumption seems to be within reasons, but the likely culprit is probably still the PSU. Shiv said that it isn't a great unit so I'll trust him there and say that it's most likely either damaged or just bad quality.

PSU isn't a great unit, both wattage and quality wise. Do you have any other PSUs or other computers whose PSUs you could borrow to test it out?

Can you recomend a PSU for my setup?

Sounds like a PSU problem.  Few things to do right away, make sure the PSU fan is still spinning and give it a clean, with it off and unplugged, with air pretty thoroughly (might as well do the system too).  Also, to rule out some thing small like a cord or whatever, replace the PSU cord with a known working one and plug it directly into a wall outlet if it's not.  There is always a chance you have a bad power bar/surge protector/ups.

 

Just comes down to a process of elimination.  Take it from someone who bought a new PSU when they didn't have to, exhaust the stupid stuff.  That being said, if you have access to a known working PSU, do try that first.  A bad PSU can be damaging depending on how it faulted.

Changed my PSU today, and I still have the same problem. What else could it be?

What model did you switch to?

[Runar Sandstaa]

I changed to a Corsair CX850M, got rid of my power bar and changed the cord for the PSU.

Do you mind saying if the new psu had a higher wattage? Do you think it was simply the mobo or did changing the psu help in any way?

The psu did have a higher wattage. i think mayby +100-150w
