Optiplex 7040 sff psu upgrade

Jump to solution

Hey.

I have a optiplex 7040 sff where i would like to have more gpu power. Problem is that original 180w AC180ES-00 psu would be a bottleneck to more powerhungry gpu. I have read at dell vx372 315w powersupply would work whit out any modification. Can someone confirm this to me?

Thank you.

vx372 315w is for optiplex XE2.  if you look at pic of that psu and compare with 7040 psu closely, the psu cases are designed differently.  I am not sure if will fit the 7040 sff case tbh.

if you look at mounting screw holes, they also seem different.

Or you can go the ugly but works option by removing internal power supply and running wires with adapter thru the hole left behind.

Just wanted to say that I just did this with a 7040 SFF. The XE2 fits but not properly. Only one screw hole lines up but I can shut the case confidently. 

I plan to put a 1650 LP in it and stick it behind my bedroom TV.
