[Leaplist] how badly did I screw up this time?

[Hank Lambert]

I did that with a computer that I brought back from the middle east. I
replaced the original power supply with a nice Antec, and all I did was blow
the supply fuse. Even though the switch was set for 115 on the PS, it never
passed the damage to the computer. Good luck, I hope your as lucky.

Dear LEAPers,

Now I really screwed up.

I had an old computer which I brought from Switzerland which had a 220V
power pack.  When I came to the USA, I bought a transformer which fed it the
needed 220V (I also had some other old stuff from Europe feeding off this
transformer).  Finally, today I decided to change the power pack and put a
US one instead of the old Swiss one.  I put it in, checked all the cables
(except, alas, one) and turned on the power.  The fan turned for about 2 sec
and everything when dead.  Turns out that I managed to check all the cables
except the friggin power cord which I forgot to disconnect from the
transformer and connect to the wall socket.  So what I did was that I feed
220V into a 120CV power pack :-(( 

The US power pack is dead, I checked with a power pack checking device
(whatever that's really called).  My transformer's fuse is burned, but all I
need to do is put another fuse in it.  My question is: how much damage did
my stupidity do to the rest of my computer?  Should I spend the money for a
new power pack, or is it likely that motherboard, proc, RAM and whatever
else is also fried?  How much of the increase from the expected 120V to the
delivered 220V will the power pack pass on further to the rest of the
computer? 

Many thanks for any info,

Andrei
