Hi Nick, OK a couple of things to check through. 1. Does the Fan on the new PSU start up ? 2. Any odd smells near it ? 3. What is the power rating rating of the new PSU compared to the old PSU ? 4. Is the PSU switched to operate at 220V instead of 110 V ? (yes I know it would have gone bang but its a check to see if it soft failed). 5. Unplug the power supply from the mother board and see if it powers up (ie the fan). (it may not as some PSU's need a minimum load.) 6. Check the power cable from the mains for damage. 7. Check the fuse in the power is either not blown and is the right rating for the PSU. There may be a large inrush current so you might have to put a higher rated fuse in to cope. 8. Check the connectors for damage, these days the pins are 'formed' pins and are easily damaged. The PSU side should be 'sockets' check that they haven't become deformed. 9. Not tooo sure of the pin out but see if you can get a DVM onto the pins and see if there are voltages available but point 5 may come into effect. 10. Plug the PSU into a different mains socket. 11. Check the plug to see if the wires are actually secured.
