William:

Dell Dimension 4700
System Serevice Tag: 993RC61
Moto: 0M3918, S/N: CN708214B5046A
OS: XP Pro, SP3
Processor: 2.80 gigahertz Intel Pentium 4

Looks like it has a 305w power supply, standard ATX.


Something like this tiny little guy might work with your power supply.

Newegg.com - GIGABYTE GV-N520D3-1GI GeForce GT 520 (Fermi) 1GB 64-bit DDR3 PCI Express 2.0 x16 HDCP Ready Low Profile Ready Video Card

or this

Newegg.com - GIGABYTE GV-N210D2-1GI GeForce 210 1GB 128-bit GDDR2 PCI Express 2.0 x16 HDCP Ready Video Card

If not you can get a ps like this :

Newegg.com - Antec EarthWatts Green EA-430D Green 430W Continuous power ATX12V v2.3 / EPS 12V 80 PLUS BRONZE Certified Active PFC Power Supply

Theres cheaper I'm sure but 5 egg rating and I've always been an Antec fan.

If you have to get a bigger PSU your options for video cards open up as well obviously.

William: You are right. Thank you for the suggestions. I think I will get the higher watts of PS.

Thanks to all the great advice from everyone. Hopefully, I will not mess anything up making the changes and will get this project off the ground and running.

Before you rush out and buy a psu best check that you have a standard atx psu and not a proprietry dell power supply, they are very rare ive never even seen one myself, you can tell them by colour wiring to the m/b connector

looks like it is an atx but i would still check

The answers I saw earlier all said standard ATX.

tbh was thinking of anyone else reading it
