I have a Compaq Presario 5330US with a 250w PSU. I've recently bought a 9500 Pro graphics card and a Vantec 420w PSU because the 9500 Pro recommends at least a 300w PSU.
The Vantec PSU arrived today and I installed it but the computer wouldn't power on.
Could this be because the old PSU had no on/off switch? It just powered on from the button on the front of the case. Are there jumpers that need to be switched? If thats the case I'm kinda screwed because Compaq apparently doesn't like giving out documentation on thier motherboards.
Also there is a switch on the Vantec for 110v/220v, which setting should that be on ?(I'm in the US if that makes any difference)
Finally, is there any way I could find out if the Vantec is defective?
Any help would be appreciated.
Thank you.
