Almost all of your hardware should be safe, simply open the power supplies and check their fuse. If you find a blown up fuse everything else will be fine.

Do not do this unless you're a qualified electronic technician or confident enough to handle PCBs with high powered capacitors.
Seriously, this is dangerous and the problem might not even came from the PSU.

Yeah thats my only advice, try resetting the CMOS on the motherboard.

Another one, resetting Cmos memory isn't a magical all purpose solution.
This is the first time I saw a reply like this, "reset the CMOS" of a non-booting system.

It could be the Board (shorted).
The power strip had a short-circuit connecting the power[+], power[-], reset[+] and reset[-] pins which could kill a MoBo.
Try this:

Try to attach the new PSU and short the mobo pins, if you dont have power buttons on the mobo (?) Maybe you dont have restore on power feature.

Do you have PC? Remove the GPUs and put them 1 by 1 in your regular PC to check if they are dead...? You can do this with ram as well.

And since you're going to a repair shop with your PSUs,
I'm not going to recommend testing them by shorting the PS Start (green) and neutral (black) cables (I'm not going to say how to test them, no) Wink

A local technician can do that better with a PSU tester.
