Phanteks Revolt X issue

IanAG · 8 Feb 2021 at 18:59

Having a small problem with my Revolt X 1200. When the ITX system is running, and I press the ATX system power button, the PSU terminates power completely. This only occurs in this order, not in reverse where the ATX system is running and I power up the ITX system. It also does not happen every time.

The system is totally dead and power cannot be restored for a short period of time, but it isn't a fuse as later it all powers up fine.

I am using the dual system capabilities, but with the 1200W PSU, don't think the specification is anywhere close to pushing the power limits:

ATX spec:

AMD 5800X
MSI X570 Tomahawk
32GB RAM
Gigabyte 3080 (2x 8pin model)
2x m.2 & 2x SATA SSDs
Full loop with D5 & 14 PWM fans off an Aquaero 6

ITX spec:

AMD 4750G
Asrock B450 ITX
32GB RAM
1x SATA SSD

I haven't been using the main ATX system as much as I would like but haven't encountered any stability issues so far (touch wood). Reluctant to take apart for proper troubleshooting given time and the loop so wondering if anyone has any thoughts/suggestions?

Cheers
Ian

Thanks for the suggestions all, will certainly contact Phanteks so they can hopefully narrow it down. Checked all connections and seem good.

Need to swap around the cooler on the ITX at some point so my try removing that from the case entirely and testing to see if that helps as it would indicate a probable short if it resolves it.

I don't generally use the 2 systems at once so not s major issue but definitely something but right.

Small update - hopefully only temporary due to the current challenges, but Phanteks support were less than helpful telling me to take it up with the retailer without a hint of technical input other than "make sure all the PSU are fully seated".

Disappointing as my previous experience with them was good.

Nothing useful from Phanteks thankfully, clearly gone down significantly in customer service and product quality, I won't be touching them in the future for anything other than a case at a push.

I did switch the motherboard as I was having some other issues, still the same with a gigabyte B550. I haven't had chance to strip it down and test thoroughly but may do so soon given my loop is due a flush.
