I Just put together a new build with asus x570-plus tug gaming, 3700x and 5700xt. At the first boot I got the dreaded white led glaring at me. I tried a lot of different things to fix it, but no go and with everything being brand new hardwaare I found it odd, so I tested the GPU elsewhere and it worked fine. But putting it back, still the dang white light.
Then on a idiotic idea, I swapped the power leads around, bot where the type that can be either 6 or 8 leads so it wasn't a problem. Neither should it really change anything, but to my surprise the system booted up and worked. Putting it back = broken, switching them around = works.
Didn't I make sure the the contacts were fully inserted, no, all of them was fully set?
WTF?? Shouldn't those two PCIe contacts from the PSU be identical?? WTF is going on? Maybe if I had a way to test the leads, it might tell me something, because this was beyond weird.
So now I want to test both the PSU and the leads. Both of them work as a 6 contact, but only one work as a 8 contact, but all of them should work. We are after all taking about a brand new Corsair RM750x and I got two of them, so I changed over the leads.. guess what?
Still broken one way and not the other, so that means its the frigging contacts from the PSU, changed over the PSU and still the same. That means that this isn't a fail or a error, it's a design choice. Damn it all to
bleep
The only problem now is that I should really need a new test monitor with HDMI and display port, a second testing mouse and keyboard package would be bad either. Then dumb me got the odd idea of setting up my Steam library with its own SSD and a slower disk for the slower games. Plus In need to change my cpu fan for a smaller one to make it fit into the case thanks to the Nocthua's double tower cooler with 2 140 fans not being small, I think I 120 fan will make it fit, so I ordered that too. Suddenly I have got parts for about 500$ coming my way, because I didn't think of this or that and oh that might be a good idea. I could build a new right for that, dang it or add a little and get a 3080 when it becomes available. I wish I knew what I was thinking in the moment, but at least the new build seems to work now.
Swapping the leads fixed it?? Who knew?? Bios firmware upgrade next.
Now I just need to stay far far way from onine shopping for a few months and live on bread and water, eh, it isn't that bad, though a few months with spending little wouldn't hurt.
