Issue with booting newly installed software.
Issue with booting newly installed software.
I rebuilt my rig this past week but I've been fighting issues with it booting properly from the get go. I've done a lot of troubleshooting over the last few days and I think I've narrowed my issue down but would like feedback if anyone has any. I've isolated my system's inability to boot to the GPU (EVGA 1080ti).
I don't know if it's because the card is failing, has a conflict with the b650 board or (seems least likely) the PSU is undersized. The system boots perfectly fine with no GPU installed. It also boots fine with my old R9 390 installed which leads me to believe there is nothing hardware related wrong with the board. With the 1080 ti installed the system hangs every single time after post at the MSI loading screen (never makes it to Windows, spinning wheel just stops).
Some notes:
* I've done a full memtest86 run on the RAM and it's flawless.
* I've updated the firmware on the 1080ti.
* I'm running the latest GPU drivers.
* I've updated the BIOS to the latest version.
* I've done a fresh Windows 11 install.
I know this is an old card for a new build but I was hoping to hold out for a couple of months before buying a new one.
The Build:
AMD 9800X3D
Thermal right Phantom 120
MSI b650 Tomahawk
Corsair Vengeance DDR5 6400 (32GB)
Samsung 990 Pro M2 Drive (1TB)
I kept the following old components:
Case (NZXT H440)
PSU - EVGA Supernova P2 650W (Platinum)
GPU - EVGA 1080 ti
I'm figuring out how everything links together with that power supply. The motherboard needs two 8-pin connectors for the CPU, and the 1080ti also needs two 8-pin connectors (or is it one 8-pin and one 6-pin?). The power supply only has one CPU 8-pin and two GPU 8-pins. I don't think it will work properly unless the supply has at least four 8-pin connectors.
The GPU features two groups of eight pins, while the CPU has just one available from my PSU. You mentioned it only needs about two-thirds of what a single eight-pin can supply during peak usage, which seems accurate. Your observation that the CPU is working fine and performing well in Cinebench is correct.
It might lead to hanging in the boot, even if the first power surge isn’t sufficient. Also, during the hanging process, what do the debug LEDs indicate?
