Add me to the list. My 1-2yr old AX860I has low 3.3V warning that comes and goes. I can play Rust, BF1, BF3, etc for hours at times and other times my pc turns off like someone pulled the cord out. No red light. Mine passes the auto test, but the 3.3V line keeps fluctuating so much from 2.8 to 3.3V. Ive checked all wire connections and I run a clean rig. I hide my wires and have a nice looking PC on the inside.

Im loosing my faith in corsair products. This is the third product in a row that I have been let down by.

Asus X99 Deluxe
I7 No overclock
32GB 3200MHz running at 2600 because its only stable at that speed.
EVGA 980ti hydro
Corsair H100I cooler (this has been trouble free for 1-2yrs now).
Acer Predator Z35 Monitor
Samsung EVO 512GB SSD X2 in RAID 0 for OS. (boots SO fast!)
3TB 7200rpm HD for user files and storage.
Windows 10

I built my PC and I sell ram for a living. (no I dont work for corsair), so I kind of know what Im doing with a PC.

Can any or all of you do me and your selves a favor. Install corsair link, go into the power supply fan settings and set the fan on fixed at 100%. Report back if your issues go away or if its still happening.

A while ago ALOT of ax1500i and ax1200i users had the same issues with there power supplys. There was a lot of RMA's and corsair actually sold ALOT of refurbished units out on newegg and amazon after that.

I tend to think there is a issue with the temp sensor sensing the wrong temp and doing a emergency shutdown. I am going to be trying to get mine fixed, if they are not willing I'm going to take it to a friend that does electronic repair and see if he can replace the faulty sensor and if all fails buy a power supply from a different manufacture.

Hello from Switzerland / Germany.
After one year of normal work and use my AX860i also began to bring the working PC down.
I checked several things because I had the hope it cannot be such an expensive PSU but...

What I found out is that when I start the PC the fan of den AX runs. When I'm in Windows it stops. Fan speed setting in Corsair Link is set to "Standard".
If the PC is getting hot it will also not start.
I set it in this moment to maximum and will check if the problem comes again.

The fan is really loud. I think I will do the RMA with this information and look what Corsair says. Second Corsair product that is broken in one year (first was a H110i GTX AiO Hydro).

Hi guys,
I have the ax860i and I have the same problem. Random shutdowns with red light. I tried every combination, different gpus, different motherboards but it still does it very often. The problem is that my psu isnt under warranty so no RMA for me. It was a refurbished unit with only three months of warranty. So now I would like to repair it somewhere locally, but can be fixed? is there something inside that needs replacement? anyone know what is the cause of this problem?

Default AX860I shutting down sometime no restart etc.

I have had this PS since 2017. I have had this problem on and off intermittently since very early on in a system I built. I have the fan speed set to a minimum speed manually and did my own curve in Link ( which is the reason I bought this Power supply, I liked the Link software. The shutdowns were very few but started to get more frequent as time went by and usually was not a shut down while on situation, but would fail to start and get the red light. I would power off, check cables, push down on Vid Card, which I thought was issue, seemed to work and once running stayed running.

Last 2 days I started to get the shutdown while running. Now this may have happened before while I was away, I just didn't notice and assumed I had sgut down. ( I often leave running ) I found this forum.

I tried removing the top left screw, and took out both top, then all 4. DIdn't matter, I couldn't run more than 20 mins, low load or gaming. WHile I was messing around, checking cables, I pushed on side of PS and it started working. I was wrong. Worse today than ever. Luckily for me, I have an old system just sitting here with a Thermaltake ToughPower 1000. It was on a Intel QX9650 ? I put together in 2005. I am running this now since I got home from work. 14 year old power-supply, and running like a champ, I will update if that changes in a few days.

I am going to take the 860I apart at work. I am way out of warranty. I suspect, that the wiring to the connections on the power supply are faulty.
since I had a shutdown when I pushed on the side with mounting screws out. I will try to confirm that. Hopefully they are soldered to the pin in the receptacles and not crimps with push pins.

My system Specs:
Asus Strix 270G Gaming
Intel 7700K
64 GB Corsair Memory
1TB Samsung 960 Evo M2
THermalTake MicroATX Cube Case
240MM TT Pacific RL240 Water Cooled CPU custom Build With acrylic Tubing, TT Pump

Default Randomly restarts of AX860i resolved.

I resolved my randomly restarting computer AX860i power supply issue by installing this stripe coded resistor (470kohm). I find this picture from Corsair website: and another one here: . Because I don`t found this resistor in my PSU mainboard, I soldered it here. And it works!

i changed the psu to a hx520w, and my pc is full stable. I thought i have memory problem because of xmp oc profil, but not.

now the ax860i is in my girlfriends machine. there's not repeat the problem. its an asus h110m-a m.2 with a pentium g4560, gtx 970, 2x4gb corsair 2133, fhd

i bought this expensive psu, because i wanted the most reliable solution :(.

Corsair. please give a solution...
Did you run the AX860i in a Ryzen system?
