Corsair HX1200i makes my USB to reboot during heavy load.

[sblantipodi]

I hope that the community may help me but I feel out of luck with iCue and my Corsair HX1200i PSU.

I had so many problems in past with my rig due to iCue.
I swapped my motherboard and CPU from Intel to AMD (from a 13900K on a Z690 to 7950X3D on a X670E) due to a DRAMM issue related to iCue and SMBUS.
Now RAM works well but now the offending device is now the Corsair HX1200i PSU (2024 version).

If I start a game or put some heavy load on the system all the USB resets, I can hear the windows ding/dong sound of devices disconnecting and reconnecting after few seconds.
All the usb resets, both internal and external ones.

This does not happen if I close iCue or if I disconnect the HX1200i power supply from the USB port.

I have wrote to the Corsair customer care, my PSU was sent for an RMA, I swapped the PSU but the problem remains.
Months passed with no solution and in the end the ticket was closed with no solution.

I tryed to RMA the motherboard, I swapped the mobo but the problem remains.
I even tried to move the HX1200i USB cable to other USB ports on a different USB controller, I tried to connect that USB cable to an external USB header using an adapter, but problem remains.

The weird thing is that the problem does not happen if:
1) I close iCue
2) I disconnect the HX1200i from the USB

The weird thing is that the problem happen immediately after I put some heavy load on the PSU like playing a game for example.

To me, this seems a design issue. Am I wrong?

Sounds like a VID/PID conflict.

Every USB device has a VID (Vendor ID) And PID (Product ID). VIDs should never conflict as they are assigned by USB.org. For example, Corsair should always be "1B1C". But if you have two devices that are from the same vendor, it is possible that the PID conflicts with another device since PIDs are assigned by the vendors themselves. When a vendor has a lot of different product lines managed by different groups (think: PSU team vs. HID team, etc.), whether the product uses iCUE or not (odds are, only one of the two as the iCUE team would have flagged two iCUE enabled devices with the same PID).

So, to troubleshoot this, use Device Manager and go to anything that is "Corsair". Go to "details" and "Hardware IDs". Make note of each PID and see if there are any duplicates.

IIRC, the PID for an HX1200i is 1C23.

thanks for the answer Jonny, I really appreciate it.
I'm a big fan of Jonny Guru since ever, I'm glad to know that your fan can find you here.

I have checked all the PIDs, there are no "duplicates".

My Corsair products are:
- Corsair Virtuoso XT + slipstream usb dongle
- Corsair Dominator Platinum RAM
- Corsair XC5 Elite LCD CPU waterblock
- Corsair XG7 GPU waterblock
- Corsair XD5 pump+reservoir
- Corsair iCue link system hub
- Corsair Lightining node pro
- Corsair HX1200i PSU (2024 version)

You said all your internal and external USB devices disconnect and tried a different USB controller (hub?). Can you list all the USB devices and hubs you are using? Perhaps you have an overload somewhere due to the devices you are using of how they are unevenly distributed.

 

[sblantipodi]

Hi,
thanks for the answer.

I use a USB Device Tree viewer app to see which device is connected to which controller.
I tried disconnecting all the external USB devices (except for mouse and keyboard), move the devices between various controllers.
I even tried disconnecting the Corsair devices that "are not strictly needed for the system" like the Waterblock LCD and the LED controller
but the problem remains.

If I connect the Corsair HX1200i USB cable, and I start a game having iCue running in the background, all the USB resets.
If I close iCue, problem is solved, if I disconnect the HX1200i with icue running, problem is solved.

As I said I even tried connecting the PSU to an external USB using an adapter and the problem remain

If you use HWInfo, at least temporarily, instead of iCUE, while the PSU is hooked up, does the behavior change?

 

[ir_cow]

The best solution is to just not use this PSU USB gimmick. What do you gain from icue saying the PSU works?

Clueless response of the day.

iCUE and HWInfo can report real time voltages, power consumption (AC), power output (DC), including output of each rail/connector, thermals, fan speed, etc.

I use "iCUE" and "HWInfo" interchangeably because the PSU functionality in iCUE is actually HWInfo subroutines (used under license).

And before you say, "HWInfo monitors that on any PSU", the answer is "no. No it doesn't." And if you think otherwise, I'll refer everyone back to your "iCue saying the PSU works" statement for reference.

 

[ir_cow]

I know what it does, just isn't necessary and if it causes all the USB devices to disconnect, easiest solution is just not use it.

A lot of things aren't necessary. RGB. Noctua fans. 8K monitors. Yet here we are....

Ok, I tried HwInfo and iCue closed, same problem.
HwInfo causes the same problem.
If I disable SMBUS support in HwInfo problem is solved.

As always, it seems that SMBUS and Corsair products does not play well togheter.
I had so many other problems related to SMBUS and Corsair products
I swapped my old Z690 platform for an X670E platform for these problems in the hope of solving them once and for all.

But how SMBUS is related to the PSU?

Shouldn't use SMBUS. It uses the PMBUS protocol. But that's internal. SMBUS is used by the motherboard.

I've never seen this issue before. It could just be a bad PSU. ¯\_(ツ)_/¯

as I said this is a fresh new PSU, it's returned from the RMA for this problem.
I even RMAed the motherboard.
in any case, thanks for the answers Jonny, I appreciate it

this forum is a better place with Jonny, glad to know that you are here!!!

The only other suggestion I have is good ol' process of elimination. Unplug everything USB (that's not critical, of course), try to duplicate the problem and then start adding things back to the build.

 

[sblantipodi]

Good suggestion but I already tried it and same problem
Thanks again, it seems that my Corsair HX1200i must work without the hardware monitoring feature. ¯\_(ツ)_/¯

Their drivers are known to be very very unstable, i have the same PSU in another rig and i don't need or use that USB thingy at all, less problems. It's doing what it should do at moment and that's what is important.

 

[TheLostSwede]

This is most likely your issue, the Genesys Logic USB hub.
Can you somehow avoid plugging things into it? As that hub is a POS and is the cause for a lot of USB related headaches.
If all headers are connected to a Genesys Logic hub, see if it helps having only one device connected through the hub, as that tend to fix the issues.
Also, are you running the latest UEFI/BIOS? As there have been some USB related firmware updates, but that was on the older X570 platform.
One option to work around this is to get a USB 3.0 pin-header to USB 2.0 pin-header adapter and connect things through the USB 3.0 pin-header.

Genesys hub is the internal one.

I tried connecting it to other HUBs, even USB 3 ones using this adapter.

but same issue.

 

[TheLostSwede]

Genesys hub is the internal one.

I'm well aware of that, loads of motherboards have one of those POS hubs on them.

Right, so I guess it might be something else then, but just be aware that the Genesys Logic hubs are known to cause all kinds of issues.

Thank you for the suggestion, much appreciated

The PSU firmware/software? No. This is not "known" by anyone but you. Other Corsair devices? Maybe. Not my circus. I try to stay in my lane

 

[sneekypeet]

Going with my gut here, and I may be way off track.

I don't see the mouse and keyboard, any chance those are corsair? Does the mouse have a stupid high polling rate?

Had similar issues when I was reviewing peripherals, went through tech with them logged into my PC, turns out if you slow the polling rate, the disconnect stopped. Could be the PSU polling too I guess.

Check here your Serial number

I had early HX1200I that blew and received brown-box replacement, it wouldn't boot at all, on other systems it would boot but turn off
apparently they have a batch of them with defect, so my brown box was replaced again with brand new and sealed PSU.

That has absolutely nothing to do with what we're talking about here.

That article refers to the previous HX1200i.
I have the new HX1200i model, they are similar but different PSUs.

My previous HX1200i (older model) exploded during a water loop test with only the Corsair pump connected.
It seems a known issue on the internet, at least if you search the internet there are a lot of posts of people with an exploded HX1200i during a water loop test.
I even wrote to Corsair when it happened asking them to inform users if this is a known issue because it's not good to see a PSU exploding on a PC that costs nearly 8000 euros without the monitor. XD
They said thanks, but not commented the problem.

Some people says that the problem depends on the fact that hx1200i was not able to handle high load on 5V/12V when no other load is connected on the main output, like in a water loop test.
Don't know if it has sense, I know that that PSU worked well for three years on a air cooled system with an aio, when I switched to a full loop, with the first water cool test with only the pump connected, it exploded after some hours.

But this is another problem and it's not related to this.
Just to say that I was having hard time with Corsair recently.

But I continue to love them.
My first Corsair product was a DDR (1) module.
