Hello, My computer's power supply is ATX-250-12Z and REV. D3R, I see that the one for has a REV D7R, will this work with my computer?

Rosslynn, I really don't know. When I replaced mine I opened up the computer and looked at the label of my old powersupply and found the similar model at Amazon. I remember going to YouTube and putting in a search for replacing a HP computer supply and that was very helpful. if you have an ipad that you can view the YouTube video as you open up your computer. In any case you really don't have much to lose even if you order up the power supply since they don't cost that much to begin with and if it gets your computer up and running its worth it.. May sure it has the same type of connecting cable connector that plugs into the motherboard. Bottom line is I don't know what the difference between the D3R and D7R is but if I was you just order it and try it. Larry and Judy

RosslynnI have no idea what the rev version change is or if that power supply will work for you. You could always return the power supply.

You would have to look at the power supply that is currently in your computer, determine if it is an ATX supply (to match this one) and determine its wattage. This information should be on a label on the side of the power supply. If it is both ATX and 250 watts (or less), this power supply will work.

This power supply unit is for the servers listed in the description and is not meant to be compatible with anything other then what is listed.If your system is not listed then it won't work plain and simple.

I use the TX750. I don't know much about the different sizes of power supplies, but since this is an ATX case I assume it will be fine.

Not without risking destroying your system. the stock power supply is only 250watts, should get an upgrade to 400-450watts, and then it will work.

I think it will work. I didn't try it with a 500w power supply. But you can check it with yourself by checking the ampearage. Check the ampearage of the +12v rail. If it have a value of more than the card requires it will good to go..

With all power supplies, it has more to do with your power requirements. From what little I know about your unit, it should work just fine. I have it in mine with an i7 processor and it works great.

Dell in the past has used a proprietary power supply that is incompatible with industry-standard ATX, but dropped this practice some years ago -- several sources says 2001, another says 2007ish. The "tech specs" document for the 745 is © 2005, so it's probably OK, but you can easily check yours to be sure. Wikipedia has an excellent article about this (under "ATX") with one section ("Issues with Dell power supplies") describing how to determine if your Dell computer is or is not compatible.

Its a 500 watt power supply you could probably google it. It shouldnt have much effect espically if you are already running a desktop.

That's more than enough watts. It should work with your power supply too. However, I would check any specifics on both manufacturers websites.

Would think this power supply should do the trick. My system is close to the one you describe and it does fine. Will let you know there is an info message about the fan on the power supply not running at low power moments but will kick in if the unit needs more power.

Worked for my DV7 and my understanding is they are basically the same. Check the input output info on your current power supply if it matches it should work fine

The power supply is for PC only. It is recommended for system using 2 or more graphic cards or several hard drives. Even if you PC do not have these configurations it will still work with your PC.

It does not say anywhere on the box what it recommends for power supply. I am running it on a 250 watt power supply and it works great. I dont have any extra stuff drawing power on the computer. And no on needing the extra wire. It just draws its power from the PCIe X16 slot, so you will need one of those. (make sure its an X16 slot and not just a reg PCI slot.

I have an HP computer about two or three years old. A lizard climbed into the power supply and that was the end of the lizard and the power supply. We removed the cover and found the part number. I don't know the difference in the D7R and the D6R, but the one you need will be on the power supply you are replacing. Easy to replace and works great.

Yes it will work. I was running mine on a 500W psu. You won't get the PCI-e 2.0 speed from the card with a PCI-e slot, but it will still work.
