Okay folks - hope everyone is well.  I've got a new-to-me media PC available which is an Optiplex 7070 SFF with a 240w PSU - according to the gentleman who currently owns it.  I have a LP Yeston Radeon RX550 (http://www.yeston.net/product/details/234/272) that I'd like to be able to use in it.  I currently have an older Shuttle XPC with 300w PSU but it was locking up occasionally when I had the Radeon card in there.  Using onboard video - thing is solid.  I am thinking the PSU wasn't really enough to power things along.

So question for the Dell Power experts (in no order) - @DELL-Chris M , @speedstep , @redxps630 

I'd like to get a hold of one of the following PSUs for the Optiplex 7070 SFF using 6+4 pins and would like some confirmation/advice/thoughts:

I've been scouring the multiple threads and seen different viewpoints from folks on the ability to use different higher rated PSUs on lower tier models...but hoping to find something specific to this need.

This was a good, but short thread too, shoutouts to @stevan1990 @JohnSnow : https://www.dell.com/community/Optiplex-Desktops/Upgrade-7070SFF-Power-Supply/m-p/7681650
