PSU Cord blew... AGAIN!

[Guest]

Heya guys,

 

I have had a few problems with my PSU cord, and this is the second time it has completely just quit on me. The first time was a week or two ago. I was putting in a new SSD, and in the middle of formatting the SSD, my PC just turned off. I didn't hear any pops or smell any smoke. I have my PC plugged into a surge protector along with my speakers, which is plugged into an outlet. I also have my monitor plugged into the outlet as well, but it is not plugged into the surge protector. I turned my PSU on and off, and I moved the surge protector to another outlet, but my PC still would not turn on. I switched out the PSU cord with a cord I had from my 500W PSU, and it worked fine. Today, I was in the middle of a game and it did the same thing. I tried the same exact thing, but it ended up just being the cord once again. I was able to salvage a really old PSU cord from my parent's Dell desktop to hold it over. I was wondering if there is anything I can do to prevent this. It doesn't seem like the outlet is the problem because my monitor and speakers were still working and on even when the PSU cord blew. Is there a more reliable PSU cord that I could get? At the moment, I plugged my monitor into another outlet in my room, and I have my surge protector with the PC and speakers plugged into the same outlet. I'm not really sure if this will help at all (maybe give the outlet some slack), but that's why I'm asking. Also, I only had this sort of problem when I put my SSD in. Could this be a cause?

 

I'm not super knowledgeable about PSUs and electricity, so please bear with me. If pictures are needed, just let me know. Thanks in advance for your help.

How does a power cord blow? You mean the fuse in it? Might be a psu problem...

Well this is a new one for me. I have never heard of the PSU cord going BAD. Thats totally shocking.

 

I think i would first check out the PSU. I could be faulty and that is why the cords are getting messed up. Did you try one of the broken power cables in another device to see if it would power another device? Also is the first one that went on you the cord that came with the PSU when you bought it?

I just tried it on my parent's Dell desktop, and it worked. I'm at a loss for words now; I'm completely confused. The cord does not work when I have it plugged into my PC, but it works with a whole other PSU. The very first cord that 'stopped working' was the one that quit out on me when I was formatting the SSD, and yes, it was the one that came with my PSU. Could this mean that my PSU is faulty? Good thing I got EVGA, right? That 10-year warranty.

I'm just as confused as you, my friend.

I have no idea either, but could it be that you're using too less of a fuse?

 

Also you're sure it's the cable? Turn off the machine if it happens again. Unplug it. Hold the power button down a few times for 1-3 seconds each time. Plug the machine back in with the same cord. Power on the machine.

I would blame the PSU to start. I doubt that the cord was the issue. Maybe an overvolt from the PSU? IDK but i would definitely talk to EVGA about getting a replacement as a good jumping off point.

Sounds just like a short happening in the psu.

Hmm, I guess it's just a waiting game for now. I'll have to wait until it happens again, and I will definitely try that. I will still keep my monitor and PC/speakers in different outlets to see if it takes some stress off the outlet; I'm not really sure if it'll help. If it doesn't happen again, maybe that was the problem? I'm not really sure. Do you have any recommendations of cords I could use instead of this old PSU cord? I feel kind of sketch with it plugged into my 750W right now. I've had never ending PC problems; I don't want to potentially hurt my system any more than it needs to be.

I'm thinking the same thing. I will wait to see if it happens again. If it does, I will contact EVGA ASAP...

Would that be the case even if it's not making a popping sound when it turns off? It just turns off as if you held down the power button, and then the cord doesn't work anymore for the PSU.

Personally i dont think i would wait to contact them. I mean we are talking about the single piece of equipment that could kill the entire rest of your system in a milisecond if something is wrong. If your experiencing issues with it, i would turn the PC off and talk it over with EVGA. Thats my personal opinion.

[Cerberus3]

Could the source be from the power outlet? You tried the cord with a different computer but it would also be a different power outlet right? This is a very odd case.

I have always had power hungry machines so I have always followed one rule with power cables. Thicker = better. Now, I have no idea if that's true as I'm no electrician but it's never failed me.

I also have my entire set up plugged into a UPS.

 

What other problems have you been experiencing?

Would it be a good idea to re-wire my 500W that I used to have in it while I wait for my ticket to process with EVGA? I'm kind of curious if the 500W would work fine with the cord that will no longer work on my 750 P2. The only crap part about that is re-wiring everything.

Yes I tried the cord in a completely different outlet and a different PSU. I always get the oddball or worst case scenario moments with my PC...  :lol: For goodness sake.

This isnt a bad idea at all. I would definitely try wiring up another PSU if you have it. Make sure your PSU can handle your components as well, or remove a graphics card or whatever.

My HDD couldn't handle Windows and Steam; it would completely freeze my entire PC, and you weren't able to do anything but turn it off. Sometimes it would behave, and sometimes it just be a jerk that day. More time than not, it was a complete jerk. I got an SSD to get rid of this problem. I was going to install Windows onto my SSD, but it wouldn't recognize the format of my SSD for whatever reason. I don't know the details; my boyfriend gets more into that than I do. All I know, is that I had to end up plugging the HDD back in so that I could delete basically everything from my HDD and clone it onto my SSD. We originally thought all of this was my HDD not liking Windows 8, so I upgraded to Windows 10. That was not the issue whatsoever. It works now though; I haven't had any freezing since. 

 

And just me changing things out in my PC hurts my hands so badly. My boyfriend lives in England, so I don't have any brute strength to take wires out and what not. Every upgrade is a living nightmare for my boyfriend and I. I've just had the worst luck with my PC, but I also did get an SSD at no charge and an i7 instead of an i5. Thanks to Amazon lol. It'll work out eventually!

I had my PC wired up to my 500W from May to September, so I don't think it'll hurt it. The only thing I had added since (power consumption wise) is the SSD. I really don't think it would push it over the edge though, tbh.

you should be fine then. try it out!

A HDD freezing is either a dying HDD, Bad sata drivers / controller, too many programs running, not enough RAM causing Windows to use the page file too often.

If it freezes again then try something I said above. People on the forums can help you with those when needed.

The computer not detecting the SSD can either be a bad SSD, Using Bios rather than UEFI, Old Sata controllers (I mean really old) , Boot device being wrong.

Do you have another PSU? If so try it, cause it seems to be a PSU issue

UPDATE

 

Hey guys Emily's Boyfriend here 

 

so after some thinking on my end i dont think its the PSU 

 

this happened a while ago with her old PC (q6600 , 4gb ram , gtx660 , 500w evga psu ) and the same exact thing happened in a completly different outlet in a different room on a different PC

 

so i just think its the electrics in her house , that being said we will try the 500w at some point and EVGA have said they will replace the PSU with an equivalent PSU if needed 

 

thanks for the suggestion tho guys
