Re: Corsair AX850 low 12v and 5v voltage with random reboots.
LoL true true but why go through the hassle of getting out a screw driver and all that for some simple voltages? I was just checking to see i I was not getting the right voltages under load. Now had I been doing something more than that yes I would of went through the hassle 😂 I cannot believe this PSU is like 10 years old and is still pumping. The only reason I think that cap even started leaking was because of the one time it got pretty hot. Either that or maybe it did just get old. However,...

Re: Corsair AX850 low 12v and 5v voltage with random reboots.
I just used it to measure the voltage the PSU was putting out under load. I have a really good one but my son used it and left it on. The battery was dead and I couldn't find a 9 volt. So the harbor freight got the job done. I forgot I even had it. It came for free with a precision tool kit I bought 😂😂😂 Anyways I'm just happy I got this fixed. To replace the unit it would of cost almost $300. Granted the new versions are platinum rated instead of gold though....Leave a comment:

Re: Corsair AX850 low 12v and 5v voltage with random reboots.
I didn't take any pics but hopefully I can find the little capacitor because the trash didn't go out yet. I did not think to take pictures because you guys are much more knowledge than me. I thought this was like really basic stuff. However, if I can find the cap I will take pics of it and tear down the PSU and show where it was....Leave a comment:

Re: Corsair AX850 low 12v and 5v voltage with random reboots.
I have good news! I found a cap that was bad. It was a little guy and was hard to see. I fired up my pain in the butt Bernzomatic butane soldering iron which luckily I was able to get enough butane in to get it to fire up and removed it. I found the same cap on another psu I had laying around that I got with a case I bought years ago. I managed to get it out as well as the bad one on the PSU I am working on. Well, I actually had to end up switching to a another soldering iron I just so happened to have laying around that...Leave a comment:

Awesome thanks for your help. Do you know a reputable place I can get a variety of good caps?...Leave a comment:

Re: Corsair AX850 low 12v and 5v voltage with random reboots.
Eeeeek okay that's out then. I guess what I will do then is get a new PSU from EVGA. They have a page where they sell bstock PSUs at a discounted price with warranty.
Can capacitors be bad and not show any physical symptoms? Like can they be bad but not bulge or be leaking? If so I was thinking maybe I will buy a kit of capacitors off Amazon as well as a soldering kit. This will give me something to tinker around with and practice at the very least. If I'm lucky maybe after recapping I will...Leave a comment:

Re: Corsair AX850 low 12v and 5v voltage with random reboots.
I found someone selling this PSU and all the cables on ebay for $40. He said the PSU will not power on. I wonder if it could be as simple as a bad fuse or something? If I purchased it between the two do you think I could end up with one functional unit?...Leave a comment:

Re: Corsair AX850 low 12v and 5v voltage with random reboots.
I believe there are two different version from what I can tell. One is the older variant which I have that is only gold rated which comes with I believe a 7 year warranty that was up last year. The new AX series had a 10 year warranty and is Titanium rated. This is why I am trying to fix it....Leave a comment:

Re: Corsair AX850 low 12v and 5v voltage with random reboots.
There is different programs I have that monitor voltages. They were showing low voltages under load. Therefore, I used a multimeter after that. If it is not caps what the heck could it be? I really do not want to junk it because I paid a good bit for it when I got it. Up until this started happening it was a solid unit.
Oh I forgot to mention. This unit had a problem with the fan header from the factory. It is a very silent unit so you cannot hear when the fan kicks on. It also only kicks on once it...Last edited by Psychedelic; 02-18-2021, 12:31 PM.Leave a comment:

Re: Corsair AX850 low 12v and 5v voltage with random reboots.
Here is some pictures I was able to take of the PSU. I do not see any bulging caps or any that seam to be leaking. Could you please point out the area in which the caps are that I should replace?...Leave a comment:

Re: Corsair AX850 low 12v and 5v voltage with random reboots.
I have not got around to taking it apart yet. However, I will be checking it out later today. Would this project be something I can tackle with any soldering iron with temperature control? I am going to order one from Amazon today since I have prime it will be here tomorrow. Like I said I'm new to all this. I have used a Bernzomatic butane soldering iron up until now. However, there is a problem with the ignitor in both the ones I have ��
I did some research and this is the info...Last edited by Psychedelic; 02-18-2021, 08:31 AM.Leave a comment:

Corsair AX850 low 12v and 5v voltage with random reboots.
Hi guys,
I am having problems with an Corsair AX850 Gold PSU. I have had the PSU FOR around 8 years but it had not been used much. This PSU was used to power two video card and an i7 CPU originally. I noticed that the 12v power was going as low as 11.4v and the 5v was going lower than 5%. I was getting random reboots. I found that the motherboard socket had bent pins and one actually broke. Therefore, I assumed that was the problem and not the PSU. I rebuilt a whole new system. This time AMD. I decided to use this PSU since I had it.
Now with the new system I am still... -
Re: New Members - please post your introductions here
Hi guys,
My name is Rocky. I work on computers and own a computer shop. I stumbled on this site because I want to get into learning how to fix electronics as well. For example I am looking to replace some caps in one my power supplies. Other than that I am a single parent to a 17 year old son. I enjoy hunting and fishing with my son. We also work on cars. I look forward to meeting new people, and having interesting conversations plus learning new things!Leave a comment:
