Question Bad board?

[ohio_buckeye]

So title says it. Was tinkering around in my pc and had un mounted the aio i was using. Plugged everything back up thought all was well so turned it on. Started smelling the proverbial magic smoke. Shut it off and noticed somehow when I remounted the aio that I’d cut cable going to the cpu header. Oops. Been working on PCs a long time and never had that issue.

Was trying a 5700g out in the system. So I removed the aio, pulled out an old wraith prism I have sitting and no boot no post. Tried without gpu still the same. Popped in a known good 5800x that worked prior in that board same story.

Specs

Ryzen 7 5800x
AsRock ab350 pro 4 from about 2017
Powercolor red devil 6700xt
Corsair rmx 850
3 sata ssd drives and a smaller nvme ssd

Did try pulling the battery also and no different results so I’m thinking the board has gone to the great beyond. What are the chances I damaged the 5700g or the gpu? The wire that was cut was just basically a fan wire that fed the aio. And it was a clean cut.

Looking at the board below just to get up and running for a year or so until I rebuild. I thought this one has bios flashback on it? Just looking for something to let it run until I retire the system or put it into another case for my wife’s home office down the road. thoughts?

Should mention that the cpu fan will not spin up at all and if I try to boot I have to cut power or unplug. Thinking I fried the cpu fan header perhaps.

Might want to tear down the system and inspect the area around the CPU's socket and the VRM area;

(notably the top most area) for any burnt or blown componentry.

IMHO, if you're needing a new board, might as well just pick up the B550 chipset.

Yeah was looking at the b550 pro 4. The b350 was working fine until the cable got cut. Because I’d powered it up to heat up the cpu before pulling the cooler. But after that cable cut the symptoms started. Wouldn’t mind picking up an Intel setup but can’t justify the extra cost at the moment.

Thinking of this board. Found they've got some open box for 135. Thoughts?

Perusing the local microcenter website and they had one of these available for 113 open box. Labeled no accessories but I figure I’ve still got everything from the old board. Thoughts? I don’t need WiFi as I’ve got a hard line connection but could order antennas later if needed.

Final update on this thread. So I ended up going on a budget and grabbed this Asus b450 board.

Popped in the 5700g and it seems that it and my ram survived as well as my gpu. So fairly happy about that fact. Wasn't intending to rebuild but done pretty quickly and I'll be able to carry the 5700g and micro board to a new build for my wife later on. It picked up everything easily since I had a b350 board previously but installed the new chipset drivers and it seems happy. Reactivated since I had my Windows tied to a Microsoft account so money saved there. At least it's running and seems happy now.
