That PSU is garbage. I'm not saying that to be mean, I'm saying it because Thermaltake Smart units are bottom of the barrel in pricing, and they have the build quality to match. There's a pretty good chance that your board failure started with the PSU. This one's up to you, but I would replace that PSU with something B-tier ( maaaaaybe C-tier ) or better from this list . As for the board, it's an OEM affair, a cheaper version of a different low-end AsRock board. Do not reuse it. Seriously, do not reuse it, period. A board that suffers that spectacular a failure is not safe to use again. It might take out other components, and there is a very real concern that it flares up again at some point. If that happens while you're not in the room with it and the board catches, you could be looking at an actual fire. There are certain failures where you can reasonably safely reuse the board, like a dead RAM slot, SATA port or PCIe slot. Fire is not a failure you can deal with and keep using the board. Fire is an immediate, automatic no-go. If you can still get in touch with the seller and it's only been a day or so, no harm in messaging him back with pictures and letting him know that the board he sold you immediately caught fire. He might take pity on you and give you some portion of your money back. The board is dirty, so it's tough to be sure, but it looks like the edge of the board where the flame and smoke came out might have already been singed before you had your spectacular failure.
Consider this carefully—your setup could be very dangerous. The PSU might have contributed, but the fire likely began at the bottom of the board. It probably points to a short circuit somewhere on the board itself or between the board and its case. Make sure all connections are secure, especially standoffs, to avoid such risks.
I recall Linus advising against placing your motherboard directly against your case for clear reasons.
Avoid using the motherboard again. The issues in the two images appear to be related to a voltage regulator close to the chipset. One of the mosfets seems damaged, possibly taking several PCB traces. It’s unlikely the board will start properly since no other VRM groups are visible nearby. This suggests your chipset power supply is likely faulty. As mentioned before, consider sending it back for replacement through AsRock if any warranty remains. Otherwise, it’s a lost chance. It would be better to get another one from a local used marketplace rather than risk further damage to other components.
It's impossible to be certain; the issue seems to stem from a poor power source, and the updated board might have increased its demands.
I don't have enough information to give a specific recommendation. Could you share more details about your needs, such as the device type and power requirements?
Wattage matters, but the real value lies in the PSU's quality. Check the tier list and choose anything B tier or higher.
