Hi everyone, I’m wondering if I can pick people’s brains, any help/advice would be much appreciated.

So my PC has been on 24/7 for the last few weeks. I shut it down today for the first time in quite some time to sort out some cable management. Now when I try to power it back on it shuts down at various times (Ranging from immediately, to a couple of minutes). I’ve took all the side panels and everything seems to be spinning and powered up. It’s a SFF build and no cables have been moved etc (everything was cable tied in place during build).

PC Spec: CM NR200 Case, 5900X, 32GB RAM, RX 6800, GB Aorus PRO AX motherboard, Corsair SF750 PSU, NZXT X63 AIO.

A question to the experienced amongst you, would I be right thinking due to the random times of the shutdowns. It’s MORE likely to be CPU temperature related than PSU power related?

So far it has shut down whilst trying to load into windows and also whilst sitting in BIOS, whilst in BIOS all SDDs and RAM was recognised.

Whilst in BIOS I noticed that only SYS1 and SYS2 fan were spinning with readings, whilst CPU fan (was not spinning and NO reading) although the 2 fans on my AIO were spinning. This is leading me to think that it may be the AIO that is at fault.

I appreciate it could be one of numerous things causing the problem. But any advice or opinions would be helpful and much appreciated.

thank you :)
 
For anyone monitoring or checking in the future, I believe it to be the AIO.

I have a replacement arriving tomorrow, I will update this thread if it solves the issue :)
 
I have replaced the NZXT X63 (Kraken) AIO and system is now back on-line.

Thankfully, I received a replacement from the retailer @ NO additional Fee :)
 
Pretty certainly it was pump which failed.
Being already running it had easier time to keep running even if developing some problem.
But shutting down PC stopped also pump and it couldn't get over initial resistance for starting to move or some kind of partial jamming.
 
Useful to know, I've just rebuilt my wife's pc and used an x63 - first couple of times I booted it I got immediate shutdowns similar to the ones you mentioned. After going to bed and sleeping on it, it stopped happening the next day without me changing anything... I'll bear this in mind if the problem reoccurs.
 
Yeah, I’m pretty new to PC building (This was only my second build). But, with the timings of the shut down being intermittent, I assumed it would be heat related.

#EsaT, your comment makes sense about being fine once running, but having issues once it had stopped.

I’m glad my initial intuition was right and the new AIO has rectified the issue.

hopefully, this post will come in handy as a reference in the future!
