Well, this is just a theory that can't be verified without a second lower power GPU to check if it starts up properly.
I'm not an OEM or vendor responsible for backing their product. I don't provide guarantees. If you return the PSU, there might be a reason behind it. If it's not broken but only slightly suboptimal for the 7700xt, I don't know what the warranty terms are.
You purchase a standalone power unit—whether for normal or questionable use—and you're left with uncertainty about its performance.
If the 550W PSU wasn't providing enough power even to illuminate the VGA LED on the motherboard, it's definitely insufficient for a modern GPU.
The issue with the VGA LED could stem from low power supply or a defect. We don’t have any tools like nanoscopes to examine electrical connections or defects.
So you have a hypothesis, but without a testable hypothesis, you only have a guess without evidence.
well I understand that but, I've tried to take out the GPU and boot on igpu, still same result, fans and red VGA led, and that was with the 650w MSI one. of course I understand that you don't offer guarantees, I was just trying to understand if this whole situation is correlated, or might be correlated to a faulty mobo, since the first week the PSU had no issues running the gpu and I didn't really stress any component yet. Also if it's of any help, the build is at worst 3 weeks old, I don't know if that changes the plan of view over anything , still thank you for your time
Halt on VGA LED is still related to VGA initialization. If the VGA is connected to the CPU, it's all about power delivery to the CPU+GPU via the motherboard VRMs from the PSU. Just like oxygen enters through the lungs and circulates in the blood through the heart.
If oxygen or power is insufficient, initializing becomes difficult. It's well understood that low-quality PSUs can fail under light loads. Tier B isn't significantly better, and 2.x doesn't have many of the safeguards found in ATX 3.1. Unless you're familiar with electricity and the nuances of power supplies, components, and tolerances, it's hard to judge what's realistic.
Ripple and other power issues could cause problems in a system similar to CO2 toxicity or cyanide gas affecting an oxygen-breathing organism. It might affect performance slightly. It 'might not' work well, and only certain parts of the PSU may not handle transients properly, leading to insufficient power and system failure.
I fully grasp what you're referring to, and your explanation was clear too. Recently, a situation arose—I switched back to the GPU and second RAM stick, and surprisingly, it actually started up without any LEDs. The display launched, and Windows logged in. However, when I tried to boot again after shutting down, the fans spun for half a second before stopping, then began flashing. To get it running, I had to turn off the PSU, wait for them to stop, then restart it, and they resumed flashing. In another unusual case, it worked if I pressed the button when the lights turned on smoothly (after switching, the lights would flicker in a clicky pattern or a smooth gradient; the PC only booted when I pressed the button during that flicker). It’s been quite confusing.
Just to confirm, each time you changed the PSU you also adjusted the cabling, correct? If you simply use any standard cables, the PSU might not be the real cause. It’s best to stick to the ones that came with its specific PSU for troubleshooting. In the meantime, consider updating the BIOS and then clearing the CMOS.
Hello, thank you for your notice. Indeed, I only used the cables that came with each PSU, and I can confirm there was no mixing. I updated via QFLASH and reset the CMOS, but the problem reappears after the first cold start. After a standard shutdown, it resurfaces again.
It's a challenging situation. The probable cause seems to be the PSU. However, would you actually purchase one just for the sake of it, and could that not address the issue? Regardless, having a high-quality Tier A PSU is beneficial, as it can endure through multiple builds, and most reputable models include a 10-year warranty. I would choose that option if I were facing the same situation.
I removed the GPU, hooked up the DP to the motherboard, and logged into Windows without using a VGA cable. After a regular shutdown, the same problem returned—fans spun, stopped, flashed. I had to turn off the PSU, wait for it to stop, then turn it back on. I needed to press the boot button on the case right when the RGB lights started flashing in a gradient; otherwise it would fail again and I had to restart everything over.
Thank you, I understand you're considering the route ahead and would like some advice.
