3.3V is present, 5V is not. Does anyone know where 5V is created?

What is 12V_PEX8_F?
I have PALIT Jetstream 980Ti 6GB missing a 5V rail, it seems that the 12V_PEX8_F (probe point) near the 5V buck converter is missing.
I have never heard of a 12V PEX rail, what is it??
Also, I thought that 5V is turned on first, then PEX?? -
Re: Where is 5V,12V rail generated - PALIT 980Ti

Hello everyone,
I'm trying to repair my old Acer Nitro 5 (AN517-54-55T5). I've already bought a new laptop, so this is more of a learning project. For the experience, with no high expectations of success.
Well, my decice specs are the following:
Model: Acer Nitro 5 AN517-54-55T5
CPU: Intel Core i5-11400H
GPU: NVIDIA GeForce GTX 1650
Motherboard: GH51G LA-L181P Rev:1c
The symptom:
When pressing the power button, the power LED lights up for about 5 seconds and then turns off. Initially, the issue was intermittent: sometimes...05-26-2025, 10:49 AM -
Hi there,
I am looking for help with my broken 980ti. Had a bad DrMos (the bottom one) and replaced it, card worked for a short moment, but I got another shortes DrMos (second one) and replaced that one aswell.
Now I don't measure any shorts, I have 12v, PEX, 5v, 3.3v all working fine (probing points on card), but I can't get any voltage at FBVDDQ or NVVDD probing points.
Where could I check to find the fault?
You think my first DrMos could be bad, because I read that the first one will activate core?
Don't want to replace that one when I can just test other...05-11-2024, 10:41 AM -
Hello Everyone,
Long story short, I got this unit for very cheap.
I've started to experiment with it's BIOS, as I did before successfully with an M900. However my very bad quality SOIC clip broken while dumping of the biosof and it must have damaged something on the panel, because it does not turn on, and does exactly nothing when powered. The maximum voltage that could have affected something is the 3.3 or 5v from the IC clip, because the unit was not powered while the bios dumping was in progress.
I've performed some measurements:

Hi,
A colleague gave me an apparently ill CORSAIR CX600.
He told me that he heard a banging noise, and smelt the magic smoke.
After tearing down the PSU, no burnt component, everything seems OK, but the PSU often refuses to stay ON. When shorting PS_ON to GND, the fan spins a bit a finally stops. No output voltages.
I tried to treat some apparently bad solder joins and finally it seems to work OK... on the 12V and 5V rails!
It's another story on the 3.3V rail...
I have some devices to test deeply PSUs (scope, AC source, electronic load)... -
Hi All,
I have this MSI GTX-980ti Gaming Golden Edition. It had shorted mosfet on memory. Replaced the shorted i.e. Q47 PK616BA with 4C09N and the card ran fine for a month. Then suddenly again the same problem. This time when i replace it 4C09N or with replacement PK616BA (Aliexpress) it gets shorted. As soon as turn on the PC the PSU shuts down and the same mosfet Q47 gets short.
What should be the next step. Kindly guide.
