PSU Replacement for a Optiplex Dell GX280

Hi,

I have a out of warranty GX280 dell machine that the LED light on the power button blinks yellow and the system doens't power on. I figure it was an issue with the power supply, So, I had another working GX280 machine I swapped PS's on the one that doesn't power on, and the system booted right up.

 

So, I know the PS is bad on this computer. I found on the dell website of 3 different power supplies that list that the PS will work in the GX280.

 

Here is the link:

My question is, would any of these work on this system?

 

The power supply model is: HP-U2106F3

 

Thanks,

Andy
