A little trick after you turn it off at the wall hold the power button in for 10 to 15 secs then turn it off at the back that will fix your problem

Isnt that bad for the psus life?

It will literally do nothing. The two switches are directly next to each other in the circuit design. Switch one off is the same as switching another, electrically.

The capacitors are all AFTER the rear power switch. Switching off at the wall or switching off at the PSU, same result.

Switching it off drains the caps. The popping noise is the inrush of current. That is the explanation given by Jonnyguru in the link I posted above.

I think jonnyguru said that switching it off at the wall AND having something plugged into the PSU that is still pulling current is what drained the caps.

Maybe I read it differently. Still not considered a fault though either way.

Females.......Can't live with them, Can't live without them right

Thanks...im starting to think me disabling a motherboard power saving setting has done this...

well its the first time I have ever had this happen in nearly 30 years of owning a lot of pc's..its a bit of a sweaty palm moment I can tell you when you have just built your pc and your greeted with a flash and a loud electric bang when you flick the power switch lol

Ok this is weird now....
Multiple people around the same time are having their psus act up....
And we have all had pops....
Are we all running windows insider?

My HX850i made a popping noise for a while when tuning on the plug at the socket.

Then it exploded.

I believe this was the inrush thermistor. It was a very loud bang, and then it was in lots of little pieces. Computer worked after PSU replacement.

The main RCD tripped for the circuit when it happened.

What psu & when did it happen?

As above, Corsair HX850i, and it broke in June. I got it new as a warranty replacement in Nov 16, so it wasn't all that old. Unfortunately it wasn't under warranty, as the HX850 it replaced was from 2010 when the warranty was only 7 years.

Ahh i see...
Ye i just got a 750 watt gold rated corsair
I been told the hx850 plugs into the motherboard usb hub and u can monitor its load and temps?? Kinda handy.. should be standard on every psu as its built into every psus I.C anyhow
