I have a HP Pavillion Model XL761 desktop with a bad power supply. It has a Liteon model PS-6161-2H1 power supply.  I replaced it with a Micro ATX V200HP power supply. Now I have no video, or I should say, I get a message saying my video adapter is installed and to go to the comtrol panel to configure it.  Can't get there.  My question, Is the Micro ATX power supply a correct replacement?  The HP XL761 has onboard video so the video connector on the PS is not used.

I found this as a replacement: http://www.usereasy.com/product_5701.html
Notice the 13a on the 12v line.  Post what the ratings were on the original power supply and the one you replaced it with - there may be a clue there.

Ok, the Micro ATX V200HP power supply has http://www.power-on.com/miathppa1.html#spec

Voltage Max Current Min Current Max Ripple Load   Line  
+3.3V 16.7 A 0.2 A 50 mVpp +5% +1%
+5V 21 A 2.0 A 50 mVpp +5% +1%
+12V 10 A 0.2 A 120 mVpp +5% +1%
-5V 0.2 A 0.0 A 120 mVpp +10% +2%
-12V 0.5 A 0.0 A 120 mVpp +10% +2%
+5VSB 2.0 A 0.0 A 50 mVpp +5% +1%

which looks like it has a decent 12v output, compared to the original.

Can you try resetting the BIOS, in case it got bad values?  One bad possibility is that when a power supply goes, it can take out everything attached to it.
