Is your phenom Phenom-X3-8450e or AMD-Phenom-X3-8450 ?
8450e is suported by that mobo but in the asus suport page you wont find 8450.
Check here https://www.asus.com/Motherboards/M4A785M/HelpDesk_CPU/
8450e runs on 65w and 8450 runs on 95w.
Does your mobo run with your old CPU?

It actually depends what you are all hooking up to it. In my experience, if you just have a hard drive, cd/dvd drive and thats it, a 250 would power it up. I would recommend a decent 300-400 watt PSU if you plan on putting anything more than a hard drive and dvd drive in it. But for testing purposes, a 250 watt should do the job. I don't know about a motherboards minimum requirements though, depends on the CPU, Memory, # of fans etc. that you have.

NVidia GeForce 9300 265MB with a 250 watt PSU


GeForce 9300GE is the video card
GeForce 9300 is the motherboard

Also 250 Watt would not be sufficient for most new video cards. Most need a 450+ for requirements.

Giga Ethernet is short for Gigabyte Ethernet which allows for more speed if you have a higher speed internet service

How much watts of power do i have?


the 9600GSO uses arounf 250 watts under load. While I cannot fing exact spec for the HP PSU I would be surprised if it were more that 350W. Is there any indication on the case or can you open the case up and look at the PSU?

9600 GSO Power

You need somthing in the order of 450W or greater. Get an Enermax, Corsair or other good quality PSU.

Comp not firing up


Something may be shorting out the board. Try taking the motherboard out and turning it on without the case. Just put the motherboard and power supply on a non-static surface. A box works well. Then use a flathead screw driver to temporary "jump" the 2 power switch pins for the front panel connection (as you wont be turning it on while inside the case).

If that doesnt work, then replace power supply. You could also take one out of another working computer just to test.

Upgrading power supply


The next time you get a PSU. Tell them what you have. Apparently you got one that is not compatible with your compaq.The power (500 wattage) will work with your MB.
Get an OEM PSU from Compaq(HP).
