Good morning wolfman and welcome back

from what I am finding you will have a hard time amazon did show these most are used I think only one company had new ones http://www.amazon.com/s?ie=UTF8&keywords=Dell%20Power%20Supply%20MH596%20OptiPlex%20GX740%20GX745%20Dimension%20C521&rh=i%3Aaps%2Ck%3ADell%20Power%20Supply%20MH596%20OptiPlex%20GX740%20GX745%20Dimension%20C521&page=1

You may also find some at a local PC retailer shop, repair shop etc. Just make sure to match it up. Mike

I have a dell dimension 4600 with flashing light will not start up.

solved the problem by holding in the start button on the ups during this computer hang up until the ups changes over, release the start button, then the computer goes through the normal start procedure.

why is it so? do not ask me I am 72 we only had gas tubes and diodes when i went to school.
