well, after looking for two hours, I have given up. I need a replacement power supply for a new graphics card in my dc5750 microtower. This is what my PSU looks like:

The insides of my computer(PSU on the bottom left): http://i185.photobucket.com/albums/x287/evildemon989/Wh...
The frontside of my PSU: http://i185.photobucket.com/albums/x287/evildemon989/Fa...
Backside: http://i185.photobucket.com/albums/x287/evildemon989/Ba...

All of these pictures should be flipped so the left is on the right and right on the left.

So, right now, I need at least a 500W PSU that fits in my comp. Help in finding this would be great.

Here's the thing. Say you manage getting a replacement psu to fit that case without spending a fortune, you are still getting a crappy power supply.

If it were me, I would dump that case, order a new case and migrate everything from your pc to it and get a good quality power supply that cost a reasonable amount of money.

You will break the bond the evil pc manufactures have you bound to and not put any more dollars in their pocket for crappy replacement parts.

I would feel comfortable saying that for what you will pay for the replacement psu to fit your case you can get a new case and better power supply and go thru the drive thru at McDonalds afterwards and maybe take a friend.

Get this psu:

and this case:

This 450 watt psu is 10x the psu that was in your case and will run everything fine. There are other good options but I have used these and they are very quite and sleek looking.

What type of video card are you running in that rig? If its an X2 or something of that nature then you will need a more powerful psu than I suggested.

Thats my 2 centavos...

That's what my friend said. The problem is that I don't have that much money, and I don't know how to migrate a computer to a different case. The GPU would be like this: http://www.newegg.com/Product/Product.aspx?Item=N82E168... just it would be GDDR3, have an HDMI and VGA port.

Its so easy to move the parts. Just take pictures if you need to so you can remember what goes where and take notes.

If you have problems just make another post here and someone will be glad to help you. I would but Im going to be gone until Monday so if its after that I will be glad to assist you if you cant find anyone else to do so.

You dont need a 500 watt psu for that video card. The one I suggested is more than enough.

Im actually running an AMD 940 x4 cpu and an Nvidia 8800GTX ACS3 video card with 5 hard drives on that psu and no issues at all.

What I suggested is what you need to do. If you buy a replacement psu, you will spend too much and also have this same problem again in less than 2 years. The parts they put in these prebuilt systems are crap unfortunately and you dont really have much choice if you dont want to face this again anytime soon...

That thing looks a bit proprietary, under the HSF shroud there may be a set of capacitators that could possibly block the holes for another HSF.

The only real problem you will have is connecting the wires back into the new case to your motherboard from the front panel and the power supply.

Take close note to those items.

Remove your old power supply (unscrew from back case and unplug wires)
Remove your DVD/CD rom(s)
Remove your Hard Drive(s) handle carefully, do not drop
Remove the video card and any other add on cards
Remove the screws that secure the motherboard to the case

You do not need to remove the memory or the processor heatsink to change from case to case. Leave these items in tact on the board and place on an antistatic bag if you have one.

STATIC ELECTRICITY IS THE ENEMY OF PARTS IN YOUR SYSTEM SO DO NOT LAY ON THE CARPET. TOUCH THE CASE BEFORE HANDLING ANY PARTS EACH TIME YOU WALK AWAY FROM THE PC AND COME BACK BEFORE HANDLING!!!

All you have to do after you get the new case is hold the motherboard over the area it is to be assembled so you know where to install the mounting post to screw the motherboard screws to the case. Tighten them down securely so you dont have any issue with removal later.

Seat the motherboard I/O backplate into the new case(the silver plate in the back of your old case where your keyboard and mouse goes.) You will need to remove this from your old case.

Install the power supply next, sometimes you cant get the psu in due to the cpu heatsink in the way. Tighten the 4 screws and lay the wires over to the side out of the way.

Position the motherboard into place and make sure the connectors line up on the motherboard to the I/O plate holes and gently screw the screws in place (loosely) until all are installed. Go back and tighen the screws until slightly snug. YOU DONT WANT TO OVERTIGHTEN, THIS CAN DAMAGE THE MOTHERBOARD.

Install the CD/DVD rom and hard drive(s).

Install the video card and other add on cards next.

Then the final part will be connecting the front panel wires to your motherboard. Sometimes the motherboard will have fine print on what pins are for what. What I suggest is you make a schematic drawing of the pins as a rectangle with dots in it and draw a + and - sign and the ID name on the side of the cable before removal from the original system. This will let you reference this to the new front panel cables in your new case.

Connect the power supply cables to the motherboard, cd/dvd rom, hard drive and whatever else requires it.

Check and recheck everything when you think you are done to make sure its right.

Pictures go a long way so take plenty.

YOU CAN DO IT!! =)

Well, I appreciate your help, but I'd just rather get a PSU that will fit my computer. I don't really have the time to put it all in a new case either. Anything?

Too bad to hear that.

If you really must:

http://cgi.ebay.com/404472-001-HP-power-supply-DC5700-D...|66%3A2|39%3A1|72%3A1205|293%3A1|294%3A50

I dont know where you are located but this is probably as cheap as it gets.

You say you need a 500 watt psu. What wattage was your old one? I only see 240 watt and 300 watt. I would prefer you go with the 300 watt but its quite expensive as I told you before:

http://cgi.ebay.com/HP-DC5750-300W-BTX-PFC-POWER-SUPPLY...

The effort and TIME you are putting into looking for a replacement will end up being enough time to do as I suggested.

I take it you simply don't want to mess with it. That's cool.

Tell me what the wattage was of your old psu...

Right now mine is a 240W. Also, that 300W is in a later model that doesn't fit my computer.

Ok, basically I need to know if this card will work with my PC:

http://graphics.visiontek.com/video/3000/3650_1gb_pcie....

They *recommend* it for 300W or more, not required. Also, my PSU is 240, but it is the power efficient version of the PSU(they make a normal 240, and a 240 active PFC). Would this work? It is the same as this:

http://h10010.www1.hp.com/wwpc/au/en/sm/WF06c/A1-329290...

just it has 1GB of ram and it is gddr3 instead of gddr2. The card listed at the hp website is officially supported by my CPU(Scroll down that page and click "View All Compatible Products". My HP dc5750 SFF is listed.)

Also, in my HP Compaq DC5750, I have the 2.0GHz Athlon Dualcore, not the highest end CPU(3.0GHz Dualcore) you can have in it, so it should take less power from the PSU. I'd really like to know if it would work. Does GDDR3 use less power then GDDR2?
