Capacitors popping in my new Corsair TX650M

I built my first PC more than a month ago, for the PSU I got the Corsair TX650M PSU because the RMX series was out of stock and I was told the TX series is almost as good and I should have no problems.

 

Then a few days ago when I turned on the switch on the PSU,I heard a loud pop. I did not know if it came from the PC or somewhere else and when I pressed the power button the PC booted up normally so I didn't think much of it. It worked for a few days and then when I was watching a YT video another loud pop, this time with a huge spark flying out of the PC, it tripped my MCB as well. I took the PSU out of the case and tried to look inside with a flashlight but couldn't really see much. I put it back in and booted up the PC, it booted fine but I turned it off again just in case, and it hasn't been turned on since then.

 

I went to amazon to look at the ratings for the PSU and most of them are very positive, but when I filtered for the 1 star ratings almost all of them had the same complaint - loud pop that shut down the PC, including an eerily similar case, where someone's PSU made a loud pop, but booting again worked fine for a few days and then another loud pop accompanied by a big spark that tripped their MCB. The only difference is this happened to them in the first week after purchase so they returned it to amazon and got a replacement, except the replacement did the same thing so they returned that and got a full refund. For my case it happened after a month so the seller doesn't cover it anymore and I will have to RMA from Corsair directly.

 

My question is: is this normal? Aren't PSU's supposed to be very reliable? It comes with 7 years warranty. Or is it something I am doing wrong? This is first time I built a PC and before this I always used laptops so I don't know much about these things.

 

The case has ample space to breathe, the PSU is mounted with fan facing down, where there is a filtered space for air intake. PC is kept on a wooden table so its not suffocated from bottom. On the behind (where PSU plug and I/O are) there is 5-6 inch space and on back panel also there is about 4 inch space for air intake.

 

Can someone tell what could be the reason?

  • Is it the fact that I plugged the PC in an extension cable? Only the PC and the monitor are plugged into it nothing else.
  • Is it because or 'dirty power' from the wall? But all other electronics have been working fine in the house for years.
  • The room has AC on whenever I am using the PC, at 24-26C and no moisture.
  • When I turn off the PC, I switch it off from the back of the PSU, but not from the wall.
  • Couple times I forgot to switch off the PSU from the back and left the PC overnight after shutting it down from windows.
  • I have XMP and PBO (Precision boost overdrive) enabled in BIOS

 

Finally, should I get a replacement for this or just look for a better PSU? I definitely don't want this to happen again and possibly destroy other components as well.

 

Sorry for the long post but this is my first PC and I saved for months to build it and I am scared.

That too, it drains the capacitors over time so the PSU has to take an inrush of current.

 

Yeah, it's best not to turn off the PSU.

 

Don't understand why someone would do that in the 1st place.

 

Just shut the PC down normally if that's what want to do and just leave it.

This is what your supposed to do. Get an RMA and don't switch it off from the back repeatedly.

I will recommend an NHu12s (or an NHd15 (maybe)) for your PC build. Quote or @ me @Prodigy_Smit for me to see your replies.

So I should not do anything after shutting down the PC from windows? I didn't know that or heard that before.

 

But if I don't turn it off from the back then there is an LED in the GPU that stays lit and I thought its best that there is no power going to the PC when its not in use.

NO......

 

If you shut down the PC at night, if that's what you want to do for some reason just shut it down from Windows and leave it.

 

Don't cut the power off on the PSU or unplug it etc....

 

You will kill the PSU in a pretty short period of time..

Yes, just shut it down from the Windows. You can check BIOS settings if there is an option to turn off the lights.

Or they could just let the PC go to sleep instead of shutting it down....

Turning the PSU off/on from the switch causes additional stress on the PSU. It's not good for it and it can cause premature wear. Modern power supplies use very little power when the system is shut down/in sleep states so there's little reason to turn it off when you're not using it. I'd only switch it off if you're swapping hardware or unplugging it to move it around. Even if you were turning it on and off every day it shouldn't have failed after only a month though. Contact Corsair support and have it replaced. When you get a replacement just leave it switched on.

 

Disable the LEDs from the motherboard BIOS settings, or don't buy products with unnecessary RGB.

I've always shut power to my main PC at the power strip every night (not necessarily for the PC itself, but to also turn off the other 5 devices connected to it and because that power strip is now remote-controlled so I can turn the PC on or off anytime from anywhere) without issue.

Yes there's inrush anytime you apply power back but any sensibly designed PSU should not have an issue with that.

 

Either that PSU was just faulty or it's lacking in the design of the inrush protection.

I did not know that. Are there other things I should be aware of? What about the monitor? Should I turn it off or not?

No reason to turn it off, it will go to sleep once there is no signal to it and wake up once the PC is turned back on.

Most computer hardware is designed to use nearly 0 watts when they go to sleep, or the main system is turned off.

 

The monitor has basically no draw, other than the power LED.  

A Printer goes to sleep and draws almost nothing.

The computer, once off, uses minimal energy to stay that way.

What is the lot code of your PSU?

 

This is the first 6 digits of your serial number.

I heard this often, but we always turn off the office PCs after finishing the day of work. Those crappy Dell office PCs could not come with good quality hardware like good PSU and mobo. However they work fine for years. I suppose many enthusiasts will have better quality hardware in their personal and gaming rigs. So how much premature wear for switching the PC on and off once a day will have in practical term?
