Power Supply

Daughter brought a friends computer home and said it wouldnt boot and she wanted to reinstall windows. I didnt know she meant it dosnt have power no lights nothing. Emachines 700ir. I have an old emachines that runs and I thought I would try a power supply swap to see if this was the problem.
Her 700ir has a ilssan isp 120 si
Mine has a deer dr- a200 sfx
Can give more specs if needed
Will this work ok just to check power supply

 

ok more specs
her 700ir ilssan ps
ac 100-120 vac 50/60hz
200-240 vac 1.5a 50/60 hz
dc +3.3v +5v +12v -12v +5vsb
6a 14a 2a 0.3a 0.72a


Mine deer ps
ac 115/230v 5/3a 60/50hz
dc +5v +12v +3.3v -12v -5v +5vsb
20a 4a 10a 0.8a 0.5a 2a

 

It's odd that your machine only has 4A on the +12V P/S, I suspect that's a problem. Are you sure that's correct?

 

yes thats what it says on ps anyway

 

Ok under her +12v it says 2a under mine it says 4a
Dont know much about power supplies but am I right that hers is a 120 and mine is a 200.
Mines much older is emachines going backwords Wouldnt surprise me.
Ok what do you think about a swap just to check ps Am I right that mine is just bigger

 

Ok after all that I checked the power supply and it worked. It was the power cord which I did try first on my computer and it worked but not on hers. Tried a different one and it worked. Jeez
Now I have a new problem and I will repost
