No, a motherboard cannot fry a power supply unit.
Hello, I assembled the PC with an LGA 1155 motherboard and a 500W PSU. After the initial boot, the PSU failed and I switched to a 600W unit, which also ended up being damaged. It's unclear whether the motherboard caused the failures or if frequent power cycling contributed to the issues.
It might be. I've seen PSUs malfunction on the first boot as well, but it seems the issue was with the PSU rather than the motherboard. Still, it's conceivable the reverse could happen, particularly with a questionable motherboard.
I don't know what psu's you have but if there's a short on the mainboard or somewhere else that forces the psu to shut-down then usually it is not dead. You should take it off the power-source, wait some time and put it back to work - but maybe not with the same board.
Since you didn’t mention the specific power supplies, it seems you might be considering low-quality, inexpensive options that may not perform well.
1- Yes, I'm using mediocre PSUs but they lasted a long time on another setup.
2- Building the system outside the case worked (including bios), but when I put it in the case, the PSU failed on the 500 and 600W units. Could the case be shorting the motherboard, causing the PSU to die?
