HP Pavilion 250 watt PSU that includes a Nvidia GeForce 9300

I just don't see how this is possible... either this PSU is way to small or this video card is a cheap low grade piece that I just spent way to much money on. I also here that if you replace your PSU with a larger one you can fry your motherboard in these PC's.

I have upgraded an eMachines PSU to a 400 watter with no problem
when I replace it's vid card with a ATI HD2400.

How can this PSU be big enough? and can I upgrade it if I wish to without frying my motherboard?

    Thank you Machi, But would it normally take a much larger PSU than 250 watts to run a PC and a decent video card... like anything other than this GeForce 9300?

The maximum output of a PSU simply means it is able to supply a certain amount of power. It can also deliver anything under the wattage. Where you fry things is where the connectors are wrong. HP, COmpaq, Dell, IBM have all, at times, used nonstandard connectors in their PCs. If you take something with a standard connector, and use it in a machine where that connector needs to nonstandard, you can fry stuff.

Presuming you mean the Earthwatts 500:
Should work, though the Earthwatts has the 24 pin ATX instead of the 20-pin.
http://www.atxpowersupplies.com/manuals/Antec-Earthwatts-EA-500D-user-manual.pdf
You just need to snap the 24-pin connector apart to make it work as a 20-pin. It can be snapped back together for future motherboards.
The Bestec is just a standard ATX power supply

Does your motherboard have a beeper? Does it emit any distinguished beeps?
First, to locate the problem, try to boot your system with only a bare minimum of components: motherboard, cpu, ram, videocard. Try your system with a known to be good power supply. Then, if possible, try it with other known to be good components. If possible, check power supply with a psu tester or multimeter (that takes some time). Every bit of description of system behaviour will be helpful.

I have a burned out Bestec ATX-250-12z power supply for a hp pavilion a320n. I need to know if a Dynex® - 400-Watt ATX CPU Power Supply, will work in its place.


yes it should do provided your current psu is not a small mATX one. ATX power supplies are pretty generic. Make sure you get one that has enough connectors to suit your system, having said that, Considering it's an off the shelf PC I would guess most PSU's would have the right number and type of connections.

Power supply or motherboard problem?


Hi talissap,

The blinking light is telling you something about the PSU. First check any AC mains voltage select switches for proper setting. US should be 115. Second if you have a multimeter, you could test the PSU for voltage. Disconnect all power to all components. remove all components from the board including cpu, memory . Leave the PSU only plugged into the board. Press power. If the fan turns on then it's not the power supply. The brand power supply isn't the best, I've seen where you need to wait for 5-20 minutes for the blinking to stop, at which time it will fire up. Now, if it doesn't power up, then it's most likely the PSU.

Good Luck,

Mark

The pc wont power up and the green led on the PSU is just flashing, is the bestec atx 250 12z broken?


Most likely yes.

I would also reccomend an upgrade to that PSU when replacing it.

Something in the 450-Watt neighborhood is usually a bit more robust.

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.
