Yes you can replace the old defective power supply with the new atx but the problem is the size. It the size it fit to your computer nothing to worry because power supply now is almost the same output only the wattages changes.

SOURCE: use nps-330ab for a normal power supply

You need to ground pin 14 momentarily to turn the power supply on. Pin 10 provides +12v, pin 12 provides -12v. Diagram here.

Remove heatsink on dell NPS-250KB


Here is a Dell NPS-250KB,

http://www.justpowersupplies.com/dell-nps-250kb-b-power-supply.htm

This is a cutaway of an SMPS similar to yours,
(Switched-Mode Power Supply),

http://en.wikipedia.org/wiki/File:ATX_power_supply_interior-1000px_transparent.png

In-between the letters B and C, and C and D, are the Heatsinks.

The shiny rectangular block looking objects, are actually aluminum fins, and put together, have a rectangular shape.
They are connected in a row with a thin metal strip.

[DO NOT open a Power Supply plugged into power!
Dangerous voltages inside that can -> Badly to FATALLY shock you!
(Fatally = Kill)

The Electrolytic Capacitors inside are designed to hold a charge, then release it all at once. Power supply unplugged from power, the capacitors inside can hold a charge for weeks, months, sometimes over a year!
They need to be properly discharged before working on the unit ]

I have a feeling you mean towards a Processor's Heatsink, inside a Dell desktop computer.

There are styles where Dell used a type of Thermal Glue, and stuck the Heatsink to the Processor.
A hair dryer set to medium, and slowly swirled around, and around on top of the Heatsink, will soften the glue.

{The above is AFTER the mounting clips are unclipped, that hold the Heatsink to the Processor}

WITH A GLOVE the Heatsink is gently twisted a little, one direction sideways, then the other direction, until it comes loose.

You can feel when the glue is soft enough, to start twisting on the Heatsink. You can also feel when it is not.

DO NOT manhandle it. The Heatsink will come loose, but so will the Processor. You will have a Processor with broken/bent pins on the bottom. This = No.

Or your reference may be to a particular style that Dell used.
This is one of many. Used on an Optiplex G150 desktop computer,

So what is the Model Number of your Dell desktop computer? Post in a Comment.
