Here some information you might need

Note: "Power Supply DC Connector Pin Assignments"

You need one that fits your case. What type case do you have? ATX is standard. Your manual says that you currently have a 300 watt PS. Buy one that is larger 400+. How does it mount in the case rear mount? Side mount? Contact Dell support for additional information. More then likely getting one with the wrong pin arrangement will cause you the most trouble, be sure before you buy. These are only general guidelines.

Dell Power supply
by mew905 / November 26, 2008 8:05 AM PST

Dell supplies a 320 watt 4-SATA, 1 P4 and 1 24 pin power supply. It mounts in the classic rear-top area. Any power supply will do but you will find that as the supplies get bigger you will have less room. I have a Gigabyte Odin GT 550 watt modular power supply and if you have a modular one the same size, I highly suggest plugging in your connectors before it goes in. the only thing to hold it up anymore are the braces at the bottom and the screws in the back. The part where the cables come out wont line up with the old one either. HOWEVER thats a somewhat large power supply. you will end up bending the rear brace down (just slightly) and the top side-panel-rails to get the old one out or new one in.

How to remove the power supply:
Disconnect and move cables out of the way
Unscrew the 3 screws in the rear (or maybe mine is the only one that lacks a single screw) around the power supply.
Pull the supply toward the front of the case until it wont go anymore, then lift up out of the case, and repeat this until the power supply is free, then slide toward the bottom end of the case (should clear the side-bracing) and lift out entirely

You may need to force it and the metal is somewhat flimsy so use firm but constant force (so if it slips out suddenly its not gonna fly off and knock capacitors of your motherboard!)

Repeat in reverse to install the new one, it is tricky, ESPECIALLY if the one is bigger.
