New Power Supply but is it faulty?

[yoosuf290]

Hello, I just got the EVGA 430W Power Supply today for Dell Optiplex 755 Mini Tower. Originally, the stock power supply did not have any problems. I got this one because I wanted to increase the wattage so it would support modern graphic cards.After I changed to my new EVGA psu, everything was going great. However, the computer restarted randomly at one point. And it was no blue screen. The restart was an INSTANT restart, as in, it was like the computer was switched off and switched on.I'm currently running Windows 8.1. So I immediately went ahead and checked the Event Viewer. And it gave me Kernel-Power (Event ID: 41) critical error. After the automatic restart, I disabled Automatic Restart from the Startup and Recovery window.This has never happened to me with my old PSU. Infact, I haven't even added any accessories to my PC (such as: graphics card) yet. The EVGA psu is running the same devices and components as the stock PSU.

So I opened up my PC to check and see if there were any loose connections, every connection is right on place.

Is there a problem with my power supply? Has anyone ever experienced this problem? I am quite worried still. However, I have not experienced another restart yet.

Other than this, the psu seem to be working fine. The fun is running and its not overheating at all.

The error ID you quoted simply means that the computer was not shut down or reset unexpectedly. It's hard to tell what caused this, if the problem persists I would take the PSU into a shop that has the neccessary tools to test if there is something wrong with it.

I also get the occational spontaneous reset on my computer and I have no idea what causes them, but it happens so rarely that I can't be bothered to do anything about it.

If you didn't have the issue with the old PSU and you do with the new one, then it's most likely caused by the new PSU. An error 41 is all that you'll see in Events Viewer whenever there's a power loss. Check the AC power cord to make sure it makes good contact and if it does, then RMA the new PSU.
