Possible PSU failure.

[Wraith]

So I brought my RIG to the missus for the weekend as her boys love gaming, and this is where my issue begins. Possibly fixed possibly not it's a waiting game right now.

So here we have the rig for clarity:

CPU i7 4790k (stock with boost enabled)
RAM 16GB Kingston Hyper X Fury 1800Mhz 1.5v stock
Mobo Asus Z97 Sabertooth Mark S
GPU EVGA GTX1080Ti SC Black edition
PSU Corsair AX860i
SSD 1 Corsair Force LX 256GB
SSD 2 Samsung Evo 860 500GB
HDD WD Blue 1TB
Cooling Corsair H100i V2

So I set her up here - Check
Power her up - Oh dear!

First no boot no post with constant boot loop.
When I do eventually get a boot I get the Asus Surge protection warning of potential failing PSU then later a failed OC warning (I know what the latter was about)

So I do the usual and strip her down and do a dry bench (on the box) run with the bare minimum.

So I check RAM each stick and both in alternate banks and with a donor rig they are fine.

Check the GPU in the donor and that's A-OK

Check CPU in the donor and that's fine.

So I try the PSU on the donor and would you believe it that appears to be fine too...

I try the spare PSU on my mobo and CPU with the memory and that's fine also...

So time to scratch my head..

I rebuilt my rig and boom, boots fine... for about an hour and then sudden shut down with constant boot loop...

I powered her off and switched wall sockets, boot her up and she's fine again all night infact. Then this morning back to boot loop, no post beeps nothing just the sound of the PSU relay. So I stripped her down again and ran the PSU self test (all cables removed/multiple times) sometimes I get the green light and the fan does it's thing and others nothing but a relay click...

I've reassembled the RIG and so far she's running fine, so has anyone else had this mysterious issue or any idea as to what it could be.?

My thoughts so far are cable trapped or fouling the test switch on the PSU, dirty electricity from the sockets here or is it simply my PSU that's on it's way to silicon heaven..

Moving a rig can be terribly jarring, even if you are very very careful. It doesn't take much to spaz out a motherboard man. I literally brought my green rig to mum's on my lap lmao.

It might have been static freaking out the board.

 

[Avet]

Have you plugged 2 separate cables in GPU? If you go with daisychain on single cable it can cause problems in some situations with high-end cards.

 

[Wraith]

only ever use individual cables I won't use daisys.

Well since I've been back at my place she's running tip top. Link is showing no unusual spikes or power abnormalities. She resets fine, shuts down fine and wakes from sleep too, I'm just baffled as too what was wrong. I'll admit I'm on edge just waiting for the random shutdown and boot loops :lol:

I've had it happen loads dude. It just literally jars a ram stick or something and the board has a meltdown lol.

Fingers crossed she is fine

As i wrote on discord, i had a similar problem with my 4790k build. It had random crashes, and sometimes it boot looped. After DAYS of fiddling around with it, i found out, that turning to XMP 2 = 2133MHz, instead of 2400MHz stopped the problem. Didn't want to add more power to the RAM, but i think that would solve it as well. I think it is the memory controller on the 4790, that gets degraded over time.
It ran at 2133MHz for more than a year. Then swapped for my current hardware, same PSU, and i have no issues at all. (I have a AX860i as well )

Just came back to my flat for the first time in a week. Turned on the power at the wall and enabled my wattage viewer and then pressed the power button. Came on, lit up, clicked and shut down. Took two more tries to get it booting.

And I haven't even moved it or touched it. Must have been a tremor lol.

 

[Wraith]

Funny you should mention it fella, just logged into GTA to check the latest update and pow powered down and infinite boot loop! Pulled the side panel hit the self test switch and hey presto she boots.

I'm calling failing PSU. Just ordered an NZXT 750W which will be here tomorrow.

Still running the AX Tom gave to me about three years back. Did give it a ruddy good scrub about a year ago? if that. It wasn't even that dirty tbh.

This is the AX860i I got from Corsair for reviewing with the new Link software it's 2 years 6 months old, it's spotless inside and out mainly due to the fan being passive and never spinning up.

Anyway ordered a new unit from EVGA just to be 100% sure and it's always good to have a spare laying around. I've checked all cables are firmly in and everything but yet still with the random shutdowns, no BSODs or error reports just power failures.

Heard bad things about the AXi. Beautiful PSUs, though !

My friend out in the states just got a 1950x and Zenith for $700. I was jealous enough, then his boss threw in a AX1600i and 16gb more Gskill Trident RGB.

Oh, and I also need to replace the 600w PSU in my Fury X rig. It was fine with a 950 in, but now the PSU is getting red hot. I wouldn't mind, but if you remember when I built it (Dianoga, the green one) you will remember it has about a thousand wires I packed into the side panel with duct tape. Yeah, that will be fun ! not.

Well I've been on Corsair's support forums for almost 3 hours now reading threads and my jaw is on the floor with how many have the same issues as me with the same PSU. Not what I expected from Corsair especially a Platinum rated PSU. I'll see what happens tomorrow.

 

[Dark NighT]

Corsair is far from great quality these days.

Yeah man. AX reliable, AXi not so much.

 

[Bartacus]

Weren't AX's rebranded Seasonics, but the AXi units were rebranded Flextronics units? Seasonic has been making some of the best PSUs ever for years, so no surprise how reliable those are. I know nothing about Flextronic.

 

[Wraith]

IT'S THE PSU!!!!

How do I know, my hand is still tingling from the massive static jolt I just received after I tried swapping out the cables. Seems the 24 Pin socket is fouling the caps on the PCB which can be seen through the fan grille so when slight movement to the cable is applied and the socket moves even a fraction of a mm it shuts down and boot loops but daymn!! That shock was horrid, right off the outer casing too.

 

[looz]

It's advisable to get checked after a proper shock, even if it's 99% nothing. Stay safe!

Thanks for the concern fella, I'm fine. A lady friend across the street is a nurse she says my heart rate is fine, the tip of my index finger is numb though :lol:. I've had many an electric shock over the years and this was nothing as bad as those thankfully but, my word did it come keen.

Going to get the bench tester out soon discharge the thing and get to the hows and whys of why it's done it hopefully shed some light and I'll get it reported here ASAP.
