Need some opinions because this GPU upgrade situation has turned into a nightmare.
System:
- HP OMEN 40L GT21 series
- Ryzen 5 7600
- RTX 4060 (original card)
- 32GB upgraded DDR5
- Corsair RM1000e 1000W PSU (Upgrade to this 2 months ago)
- Windows 11
Attempted upgrades:
- PNY RTX 5060 Ti 16GB
- MSI RTX 5070 Gaming Trio OC
What happened:
The new GPUs would initially sometimes display video and even reach Windows, but then:
- black screens
- driver instability
- BitLocker recovery
- random hard shutdowns
- no display output after reboot
- system power-offs during troubleshooting
Important part:
The original RTX 4060 still works perfectly fine and the PC is stable with it.
A repair shop has had the machine for several days and apparently isolated the issue down to power delivery / PSU behavior. They said the newer GPUs are causing shutdowns because “MAYBE” (but not sure) aren’t receiving stable enough power even though the PSU is a Corsair RM1000e 1000W unit.
The confusing part to me:
- the PSU SHOULD theoretically be more than enough
- multiple GPUs reproduced the same issue
- old GPU works perfectly
- new GPUs fail under initialization/load conditions
At this point I’m trying to understand:
- defective PSU?
- transient spike issue?
- bad modular cable?
- RTX 50-series power behavior?
- OEM HP motherboard weirdness?
- protection tripping?
Would appreciate grounded feedback from anyone experienced with modern RTX power behavior because this has become one of the weirdest PC upgrade experiences I’ve had.
