I have a Dell precision 340, and sometimes when I turn it on, the power supply (or the fan in it?) is making a loud noise. Does anyone know how hard it is to replace the power supply oneself? I'm not afraid of doing it if it just involves some screws and unhooking some cables--is there anything to watch out for?

Thanks.

If you can replace the plug on a lamp cord, you can replace a PC power supply. The cables are such that there is only one way to hook them up - unlike the lamp cord where there are two ways (and one of those is wrong).

That said, the biggest deal will be getting the power supply. It is my understanding Dell PCs have non-standard powersupplies and mother boards. So you probably have to get the power supply from Dell.

Dell does a good job at sendding (or putting on the web) instructions.

Thanks for the advice and the links. Do you think it matters whether I get a 250W or a 400W? Would something like this work?

Hey Jim,

I have a Dell precision 340...

Do you think it matters whether I get a 250W or a 400W?


It could, depending on the power needs of the computer. As Bob suggested, use PC Power & Cooling. I've purchased hardware from PCP&C before with no problems. Personally I'd call them and ask them for help finding the correct PS for your computer...
