Recently, i received many motherboards & power supplys. Their
condition are unknown.
They may be bad.

I know that a bad motherbard could damage a CPU sometimes.

Is there any way to test an unknown motherboard without frying the CPU?

the CPU and motherboard?
 
No. And good luck there. I've tried it. My experience is if you
get lucky, and find a good mobo and psupply right away, you
can use that supply and cpu to test the rest of the mobos
with fair safety. I've never blown a cpu in a bad mobo. BUT
!!!!! a bad psupply can sure pop your good mobo. I would
buy a cheap psupply tester ... NewEgg. If you are not working
in a high school or something like that where you are expected
to do stupid things, I would NEVER try to put refurb junk into
a production environment. You will generate a million bucks
worth of downtime.

Hi,
You can find out how good a Power Supply is, usually by buying yourself
a inexpensive multimeter and test the Power supply. I have seen them as
cheap as 2 bucks and you really do not need anything fancy. There is
usually some sort of electrical diagram on the Power Supply. Either on
the inside of it or stickered on the outside. If the unit is a Power
Supply/motherboard combo (closed architecture) find the specs on the
motherboard. This can be done by looking at the Motherboard and looking
for the name of manufacturer and model . Then do a quick Web search.

To test out unknown Motherboards and Power Supplies I would start out
with a good Power Supply and then try the questionable Motherboard.
From there I would use a multimeter and would usually test out the

Power Supply before pairing them together.

Usually if there is a internal problem with a power supply, the fuse
located inside the Power supply usually blows and nothing works.

The above link actually list out the voltage for ATX power Supplies and
some troubleshooting steps.

I hope this helps,
