Upgrade HP Compaq 6000 Pro Microtower PSU

[asianman]

Hi everyone.

I want to upgrade HP Compaq 6000 Pro Microtower PSU which has 320W. I want to upgrade in order to accommodate the right wattage for my MSI GTX650.

The problem is that no standard unit with what looks like HP proprietary P1, P2 & P3 outputs


Here is the model of my desktop:http://bizsupport1.austin.hp.com/bc/docs/support/SupportManual/c01883660/c01883660.pdfanual/c01883660/c01883660.pdf


Below is the picture of the current unit of PSU from HP. Can anyone tell me what HP or 3rd party PSU options I can use because I can’t find any info? Thanks

It would help if we knew where on the motherboard those outputs go - what do they power?
P1 looks like a standard Video card output.
P3 looks like a standard CPU power output.
No idea what P2 is.

You also need to pay attention to the power supply form factor. A standard ATX supply has a standard screw pattern to attach to a standard ATX case. But some manufacturer's use their own proprietary form factor. You need to check.
