Computer/Power Supply "Pulsing"

[Manuel Chachere]

I've recently sent in a RMA for my Z170A GM7 motherboard from MSI to get "repaired" for an issue that has been going for atleast 3-4 months. Prior to that, I had my PSU, AX860I, sent in for a new one hoping that would solve the issue from the start. I have been told by MSI that the issue is coming from the PSU and not the motherboard. Before I enebibly send in the PSU for "repairs" or what not, is there any knowledge on the issue.

Windows gives me the Power Kernal 41 Error code. It happens at any given time, even during bootup or idel at home/start screen. I've tried pulling both memories from the board, the drives and the VGA. I was assured that the power supply was enough for not only the 980TI but also atleast a 30% over clocking when using the programs that MSI has approved.

Again, my issue is that the computer turns its self off (crashing) then pulsing between off and on, making a clicking sound as it does that.

I've sent this into Corsair again and I got this response
"Not something I've seen before, this isn't usual behavior."

MSI has assured me that its the PSU and not the Motherboard. I beginning to think maybe I've done something wrong when building the computer but im not sure. Short of taking it in physically im stumped. Also, its not the outlet. It happened when i first built it and when i moved it continued to happen. I've tried switching to and from the wall outlet to the power surge.

As of typing this, its been pulsing off and on for over an hour now.

PSU: AXI 860
CPU i5-6600k
GPU: GTX 980TI
MoBo: MSI z170A GM7
Cooler: Corsair H110i

Temps are fine.

Sounds liker a power supply issue , most Kernel 41 issues are.

What is the CPU temperature in BIOS?

This is incredibly unusual for that PSU. Something is horribly wrong with it, and that PSU doesn't have problems very often at all.

The design is very solid, and it's also one of the flagship units from Corsair. If you send it in, you can expect some important people to take note of it. They will also send you a working unit, and some engineers may contact you to figure out what went wrong.

Yeah, I'm waiting on a response right now to send in the PSU (again). As far as temps go, it hasnt made it to the 2 second power on stage yet since yesterday, where it was just sitting idel for about.. 2-3 hours at the home screen. Honestly trying to figure out how I can show this over the internet lol. Guess i could record it if my phones good enough to pick up the small clicking noises it makes as the power shuts off and on. Whats my luck that I would get 2 bad power supplies in a row? Thats what conserns me.

Update: Called Corsair. I'm buying a new Powersupply and they will refund me. (They dont have any in stock at their warehouse >.>)
But there was no info on this issue other than it sounds like a PSU Issue. x.x Its been over a month since i've played computer games. I think I need to an AA class for gaming in a few if i dont get a fix soon.

Atm, I'm guessing this is going under PSU issue tho I wish i could get a better understanding on if it really is my fault or the PSUs fault. Guess i'll know once i get the new PSU.

If you're interested in the details of it, it sounds like there's a problem in the PS_ON# circuit. It could have been a capacitor that was installed backwards, as that would gradually get worse over time. It would also mean that someone is about to be fired.

There's a chance that there's a bad solder in that circuit, but I doubt it with that unit, as most of the soldering is automated. It could also be a damaged IC, but they take serious precautions to avoid that. Again, if it's either of these, then someone is about to be fired.

Regardless, unless you went and shoved a screwdriver into the unit, it's unlikely that you're responsible for the issue. Those units have protections against almost any conceivable mistake a builder might make.

OH, well then. That makes me feel a whole lot better considering this will be my 2nd RMA and 3rd unit. I'm still holding Corsair high but just odd that this has happened twice now. I guess 3rd times the charm?

It's hard to imagine what would cause that. Do you have power quality issues where you live?
