There is a method to safely disconnect the power cable if needed. A properly functioning PSU rarely requires such measures. Your situation suggests multiple problems at once, not just a single defective part. Most likely, the issue stems from the PSU itself, as it controls all components inside the PC. When the PSU fails (even with high-quality units), various malfunctions can occur. Cheap or low-quality PSUs often cause immediate failure, while even decent ones can fail gradually due to voltage issues or ripple. This is why over-provisioning wattage is recommended. I usually maintain a 200W margin, adding extra capacity to account for peak loads and potential spikes. For example, my current builds use 650W units that work well with 550W models; a 450W unit would be the absolute minimum. Higher capacity ensures better stability over time without worrying about power shortages or PSU degradation. I’m considering upgrading to around 550W for my upcoming GPU, which pushes my needs closer to the limit of my existing 650W units. Switching to 850W PSUs would give me enough buffer for at least a decade.
Well, for one thing, you're using an EXPO set designed for an AMD system on an Intel setup. What is the actual model number of the memory kit you're employing? And if you had to completely disconnect the power supply in order to get it to start up, that would usually point to either a PSU or motherboard problem, with the responsibility mostly lying on the power supply but not completely excluding the motherboard either.
What model year is that RM1000x? I wonder why people often say the system was built 2-3 years ago, but it turns out the power supply wasn't bought new at all and is likely much older than the rest of the equipment. Also, there have been several different RMx updates in the past five to six years, so knowing the exact revision (like ATX 2.4, ATX 2.5, ATX 3.0, etc.) would be helpful.
It's either a 2015 or a 2021 model. Corsair didn't release a 1000W RMx unit in the 2018 series. The build quality is outdated, making it unsuitable for the 2024 series. Both 2015 and 2021 are ATX 2.x models.
But you're taking for granted that the PSU hasn't been swapped out since the system was assembled, which isn't certain—we can't be sure. It might be older or newer than when it was built. It's possible it was bought at any time from 2015 up to now, and considering both the model and its age could matter, it would help to clarify, particularly given the presence of ATX 3.1 versions of the RM1000x, which could suggest a more recent purchase or not very long ago.
It’s the 2021 model
I haven’t swapped out the PSU, it’s stayed the same throughout.
I’ve experimented with different ports, but the problems persist.
The kit includes both EXPO and XMP profiles. In the BIOS, which profile is active? It's possible there are multiple profiles available for both EXPO and XMP, so it would be advisable to set it to XMP 1 or the first listed profile that matches the advertised specifications of XMP Profile #1: DDR5-6000 CL36-38-38 @1.35V instead of any EXPO or the XMP 2 profile, which operates at a 1.25V setting and could cause issues.
It's also important to confirm precisely which DIMM slots are installed. They should be slots A2 and B2, located on the second and fourth positions from the CPU socket towards the motherboard edge, with B2 being the closest to the edge. Any deviation from this configuration might lead to problems if only two DIMMs are used.
Given that your PSU is a high-quality model and relatively new, it's less likely to be the cause, but not impossible. Before investigating the PSU or motherboard further, it's wise to rule out other factors first. One possibility is that a motherboard pin was slightly bent during CPU installation; over time, weight and vibration could have caused it to become more bent, leading to contact issues and errors. This can happen more often than expected.
I recommend thoroughly verifying all PSU cable connections at both the PSU and the motherboard to ensure they were fully seated initially. Even a slight looseness could result in intermittent contact problems. This step is worth considering, especially since the VMD controller manages NVME storage connections directly to the CPU, making pin or board issues more likely. Disabling XMP might have temporarily resolved your issue, so it's worth checking if that was the case.
