So I had to replace my 1000w Seasonic PSU from early 2018 because it was causing my entire PC to shut down when my Vega 64 LC has transient power spikes. The PSU is overly sensitive to them.
So I did a lot of research including on the [Linus Tech Tips forum](https://linustechtips.com/topic/1116640-psu-tier-list/) and decided to go with the new Corsair RM1000x PSU which had a refresh recently.
When it arrived I pulled my Seasonic PSU out. My case is an old Corsair Air 540. My motherboard is an Asus ROG Crosshair VI Extreme. This is when the problems started. I thought it would be easy and take me 15 minutes at most but boy was I wrong.
The first problem is that despite Corsair saying the Air 540 is compatible with EATX motherboards it's really not. As you can see from this picture the grommets in the case do not align with the motherboard's big power socket. https://i.imgur.com/DsQgtJ5.jpeg This gave me some trouble with my Seasonic power supply when I assembled the PC years ago. Because it's hard to bend a thick power cable to get it into the socket. However, this trouble was TEN times worse with the power cable that came with my new Corsair PSU.
As you can see from the pic, the Corsair power cable for the motherboard has a MASSIVE piece of thick tape on the end of it. Exactly where I need to bend it to get it into the power socket. On top of that there is a super hard knot right in the middle of the tape. https://i.imgur.com/j9WLHpc.jpeg
I am not joking when I say it took me over an HOUR to get this cable plugged into the motherboard power socket. I tried bending it every way. I tried running it through every grommet. Eventually I had to remove the front case fans and bend the cable EXTREMELY hard to get it into the power socket. https://i.imgur.com/WmDOxbs.jpeg
Then I ran into another problem with this power cable. When plugging it into the PSU the little plastic clip at the top was blocked from running into a metal cap inside the PSU itself. As you can see from the pics the plastic clip is not depressed like it should be. It won't go in any further because its path is blocked by that cap thing inside the unit. I tried pressing it down and it won't go down. Either the plastic clip needs to be shorter or the cap inside the unit needs to be moved. https://i.imgur.com/EpvXT7X.jpeg https://i.imgur.com/4AynYeV.jpeg
Another problem, at the top of my motherboard beside the 8 pin CPU power socket there is a smaller 4 pin power socket to the left of it. This is for when your CPU needs more power than normal. As far as I can see my Corsair PSU didn't come with any 4 pin power cables for this socket. https://i.imgur.com/5x6Sqe3.jpg
The next issue, the power cable that runs from the PSU to the wall outlet is too short imo. For the price I paid for this power supply I expect a longer wire.
Another annoying issue is the PCIE power cables that came with the new PSU. For my power hungry GPU it is recommended to use two separate PCIE power cables instead of just one with the split at the end. The problem is, all the PCIE power cables that came with this new Corsair PSU have a split at the end. That means I now have two splits just hanging off the GPU and it ruins the look of my build. I did not have this problem with my Seasonic PSU from early 2018 because they provided PCIE cables without a split at the end. https://i.imgur.com/Z78GUHB.jpg
For the price that I paid for this new PSU and the fact that these products should work with each other properly I am really unhappy. I have bought a lot of Corsair products over the years but this experience might make me switch to different brands.
I was going to buy a Corsair 7000D (really like how it looks) case because I have a new CPU/motherboard/NVME SSD to install but now I don't know if I am. I don't want to buy it and end up having another extremely frustrating and disappointing experience with it. Especially considering its high price.
I hope a Corsair rep reads this.
P.S. The amount of tape Corsair is using on these cables is completely excessive and achieves nothing but making them harder to bend and install. This is another thing my old Seasonic did much better.
