Question about Compaq ( 277498-001) Motherboard
I need the pdf diagram for jumper sitting ( power switch - restart - etc . . ) .
the power supply does not work and I have to replace it.
do I have to put the original one or I can put any power suplly have the same socket
As for the Power Supply 99% sure it is an ATX which as long as you get the same Watt as the existing you will be okay. Make sure you look at your existing connectors to see if you have a 24 pin or 20pin motherboard and 4 pin or 8 pin additional power plug (black and yellow wires) and the new power supply has matching connectors....older ATX supplies have only 20 pins, but there are converters from 20 to 24 pin available.
Watch for the new power supplies and your drive connectors as some of the new power supplies have limited ATA plugs...if you have a lot of ATA devices you might need SATA power convertor plugs or ATA splitters to get all you ATA devices up.
