I just sent the PSU back, and I'm getting the Corsair RM1000x 1000W tomorrow. Something that i have failed to notice/mention that has been going on this whole time after the shutdowns is that the PC takes longer to post(?). After i press the power button, everything inside starts up normally, but the keyboard, mouse and monitor takes ca. 7 seconds extra from what they used to to receive image/light. During this time, the top right light on the MB next to the CPU starts out as orange, then switches to red, then goes to white and then the monitor, keyboard and mouse turns on. I don't know if this is an indicator of anything, just thought it was worth to mention. As of now, i have temporarily plugged in the old PSU and going to try to play some games to see if anything else is different. Thanks for all the help so far, and hopefully I can get some more answers tomorrow when breadboarding
From my tests, everything works when the PC is placed down. After I raise the PC, it stops working. I attempted to apply slight pressure on the GPU while it was lying flat to mimic the heavy load, which caused artifacts on the screen. It looks like the MoBo PCI slot may not support the weight, or the card itself might be struggling. Since no artifacts appear when I flex the old GPU, it seems this one is too large for its own needs. The card didn’t come with an extra support slot like the other 7900 xtx models, which increases the chance of internal stress leading to failure. I also checked the screws on the GPU, but they seem correctly tightened.
Update: This GPU is being sent back via RMA. I tried playing Overwatch 2 at full settings, then closed the game and the PC crashed immediately. I encountered issues restarting it. There appear to be several problems—not just the sagging—so a replacement GPU is necessary. It seems the card can’t handle the sudden drop from high power use to low, and it gives up quickly.
Thanks for all the assistance from everyone who responded!
All GPUs with three or more slots should have corresponding GPU support built-in. Otherwise, the GPU sag can lead to various problems. This may result in artifacts or even damage to the PCB near the PCI-E slot, potentially opening the MoBo PCI-E slot. Have you tried testing it with a Corsair RMx 1kW?
Yes, it still crashed upon exiting games. During my last night, I realized something. I had been using two PCIe cables—one single and one daisy-chained. After some research, I found mixed information. Some people say they’ve used this setup for a year without problems, while others mention instability and even melted cables. This could be the reason for the crashes, since two cables only provide 600W. I’m still going to return the card because the PC stops working when the card is horizontal, but I plan to use three single PCIe cables moving forward for safety.
No. The specifications indicate different power ratings based on the number of cables. One 8-pin PCI-E cable supports 150W, a 6-pin one 75W. Using two of each gives 300W, three 8-pin cables reach 450W, and four achieve 600W. This is why the 12VHPWR adapter features four 8-pin connectors to deliver up to 600W.
