an 8250 Dell PSU on ebay for $23, but the shipping cost is $53 (!).

the dell dimension 8250 has a generic atx power supply. the propritary
dell power supplies pre-date this model buy perhaps two generations.
dell sell replacement power supplies for about $30 plus shipping.
genuine dell replacements can also be found on ebay starting at about
$22 delivered. i would avoid non-dell replacements despite claims of
high wattage unless it is from a reputable company in which case the
price would likely be over $90. plus the generic ones may have the
socket for the power cord in a different place, or a switch or light
that protrudes and makes it a bit more difficult to fit (may have to
bend part of the opening to make it fit). alternatively you could
simply replace the fan in your current and obviously working unit. it
is a standard 80mm fan that cost under $5 delivered from many sellers on
ebay. but a word of caution before installing such a fan - the pwoer
supply is sealed for a reason - it contains potentially leathal
electrical charges. so if you don't know how to ground electronics then
you should not open it. but if you do then go ahead and get a cheap
replacement fan and install it. and instead of soldering it to the
circuit board you may find it easier to just cut the current fan wires a
few inches from the board and slice the new fan to those wires. before
closing up the power supply note the direction the fan blows air... it
should be blowing air out of the power supply. good luck.

Thank you for the reply. I don't think I want to try replacing the
fan. I think that getting a genuine Dell replacement on ebay is what
I'll be doing.

It's probably for a reason that most of the small sellers of Dell
parts are in Texas. A year ago I called Dell for a replacement power
supply for a Dell office workstation, and the tech rep said that Dell
didn't stock that part any longer and to buy it off Ebay. I went to
Ebay, and lo and behold, almost all of the sellers of that part no. were
based in Texas. Dell must save on warehousing slow-moving small
profit items by unloading them to the small mom-'n-pop sellers.

Looks good, thank you.

more expensive than dell spare parts when you add in the shipping... and
dell has a 30 day return policy on parts and 90 day warranty.

I have a Dell 8250 that started making a buzzing noise a good while
back. I opened it up and did a good cleaning of crud off of the fan
blade, and that helped. It was more quiet but still making some noise,
especially when it got hot enough to rev up the fan over the CPU.
Turned out that the vibration was causing the noise, and I was able to
cure it by squeezing a small piece of rubber in between the casing and
the body of the heat sink shroud.

That's what I thought at first, that it was the CPU fan, but I opened
up the computer and it's definately the power supply that's making the
noise. And it's not the fan in the power supply that's making the
noise, it's the power supply itself.

I bought this:

Yes, that's Dell's Canadian website, I live in Canada,
It cost me $59.99, free shipping. Fast shipping, I ordered it last
Friday and got it on Monday.
I installed the PSU today, everything went smoothly except for the
wire that connects to the video card - it was too short. This wire
comes off from a wire that goes to a hard drive, and there was no way
that both could be connected. So I looked at the old PSU, and saw
that one of the hard drive wires didn't go directly to the hard drive,
but was plugged into another wire that had the hard drive connector
and a long wire that went to the video card. So I took that
"extension cord adapter wire" off of the old PSU and used it for the
new PSU.
