I just bought a new Corsair HX1200 PSU a few weeks ago and found that recently it has been flickering my computer on and off. I found out because when I was experimenting with the main power cord (3 pin kettle cord), I found that touching it even slightly would shut the computer off, but still leave all the RGB lights on (so it seems its still getting some power?). When I pushed the cord hard into the PSU, the computer turned back on, but as soon as I let go, the computer shut off again. So it seems the cord just can't go in far enough for some reason. I don't want to push in the cord too hard as it could damage the PSU, nor do I want to prop the cord in place with books or tape. How can I fix this? Why is this happening with a brand new PSU? Is it worth while buying a new cord (FYI I am using the cord that came with the PSU).

I just bought and assembled a new PC which is shutting down from time to time unexpectedly. The PC shuts down either when the GPU is in moderate usage or no usage at all (so basically randomly shuts down whenever) and I am not overclocking the CPU. What's also strange is that the RAM and cooler fans RGB lighting, as well as some motherboard LED's stay on after shut down. I have already checked CPU and GPU temperatures and these never go above 60C (I am doing some light machine learning, no gaming). So I don't think it's an overheating issue. In addition, the system is brand new and kept in a spacious well ventilated area, so there is absolutely no dust anywhere inside or around the case. Not shown in my system specs is the AIO CPU cooling system - which is the Corsair Hydro Series H100i RGB Platinum (yes, I used plenty of thermal paste between the cooling block and CPU heat spreader). I bought these parts on Newegg, many of which came from the US and I am now using them in the UK. I feel the PSU is definitely powerful enough for this system at 1200W, but I am unsure if using a wall adapter for US to UK plugs is causing the issue or if it's something else. Can anyone advise steps I could take to check what would be causing the issue to fix it?

I recently bought a HX1200 PSU, and the main power cable (that plugs into a wall socket) comes with a US 3 pin plug. On the plug it says "15A 125V 1875W". I have a separate "travel" adaptor where it says "13A 250V CHECK YOUR APPLIANCE IS COMPATIBLE WITH 250V~ SUPPLY". I'm not entirely sure if the specs above make the adapter and power cable compatible or not. Would it be recommended to get a power transformer of some sort (if so, what brand / model)? Or is it ok to use my standard adaptor? (Apologies I couldn't upload any photos despite trying jpeg, jpg and png; the uploader always threw an error saying these weren't valid files).

I noticed that the Threadripper 1920X is rectangular (approx. dimensions 7cm X 5cm), while the cooling base of the H100i is square (approx dimensions 5.7cm X 5.7cm). This means that the cooling base wouldn't fully cover the CPU when mounted. Is that an issue? Should a different cooler with a larger, rectangular cooling base be used to cover the entire CPU, or does it not matter? In addition, the H100i comes with pre-applied thermal paste (a very thin layer); is it necessary to apply more thermal paste to the CPU before mounting? My instinct tells me it is, just to be safe. Any advice / tips / links welcome. Thanks in advance
